I can’t find a single pair in the US for sale.\u003c\/p\u003e\n\u003cp\u003eThese particular units were sold new ($65,000) to one of our clients many years ago and were well cared for. A move and downsizing prompted this client to return them to us and we were happy to get a chance to hear them again. And wow, they are as nimble and powerful as we remembered. These are capable of over 118db mostly due to their 5 internal amplifiers (150W for each pair of woofers, 100W for the tweeter, and 100W for the mid).\u003c\/p\u003e\n\u003cp\u003eWe have a matching DSP5500 in case you’re looking for a killer home theater system. Drop us a note for details.\u003c\/p\u003e\n\u003cp\u003eThe current version of these speakers (DSP8000SE) retails for $80k. There is an upgrade available from Meridian which brings these original speakers up to the SE designation by replacing the electronic pack and the tweeter resulting in an updated DAC as well. This upgrade is available for $20k, but we would be willing to upgrade them for you for an additional $15k. Drop us a note if interested.\u003c\/p\u003e\n\u003cp\u003eCondition is very good for its age. The gloss black paint is super clean and most buyers (except for the super critical ones) will be pleased. There is a ding on front lower corner of one of the satellites but it’s not very noticeable. All the drivers are absolutely perfect and the amplifiers all work as they should. The grills are also perfect (not pictured).\u003c\/p\u003e\n\u003cp\u003eWhile most people will use these speakers as part of a Meridian system, they will work very well as a stand-alone system. They feature two digital inputs and come with their own remote so it would make for a great, super simple digital system. Connecting a simple media streamer would result in a complete system capable of outperforming just about anything out there. We recently auditioned these with a Mytek Manhattan connected directly to the digital input and got amazing results. Simplicity at its best! A pairing with a Meridian Zone Controller would also provide a simple and powerful solution. Of course, you can also choose to integrate them with a full blown Meridian system as most will do.\u003c\/p\u003e\n\u003cp\u003eThis listing includes the 2 speakers, 2 power cords, 2 Meridian Link cables, user manual, and new remote.\u003c\/p\u003e\n\u003cp\u003eThere are many glowing reviews for you to read on the internet so I won’t go on and on about these. Keep in mind this is a flagship product from an amazing and innovative UK based company and they don’t come up for sale very often. So if you’ve wanted a set this may be your best chance. While the price tag may be high for a set of speakers, keep in mind they essentially include an internal amplifier, preamplifier, and DAC which in my opinion makes them a great audio bargain.\u003c\/p\u003e","brand":"SkyFi Audio","offers":[{"title":"Default Title","offer_id":9156856447020,"sku":"Meridian DSP-8000","price":0.0,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0003\/3275\/9084\/files\/meridian-dsp8000-powered-speakers-629.jpg?v=1770235159"},{"product_id":"benchmark-adc1usb-analogue-to-digital-converter","title":"Benchmark ADC1-USB Analogue to Digital Converter","description":"\u003cp\u003eBenchmark ADC1USAB \u003c\/p\u003e\n\u003cp\u003eHighly reviewed ADC from Benchmark.\u003c\/p\u003e\n\u003cp\u003eThis unit will convert analogue to digital, not the opposite.   Perfect for digitizing LPs or tapes.  Capable of 16 or 24 bits with USB output.  \u003c\/p\u003e\n\u003cp\u003eComplete and perfect condition like the day it left the factory.   Includes all packaging cables and paperwork.  \u003c\/p\u003e","brand":"Benchmark","offers":[{"title":"Default Title","offer_id":9326603010092,"sku":"Benchmark ADC1-USB","price":0.0,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0003\/3275\/9084\/products\/benchmark-adc1-usb-analogue-to-digital-converter-amplifier-638.jpg?v=1673887611"},{"product_id":"dynaco-pas-4-tube-preamp-and-stereo-400-series-ii-solid-state-amp-combo","title":"Dynaco PAS-4 Tube Preamp and Stereo 400 Series II Solid State Amp Combo","description":"\u003cp\u003eGorgeous \"almost vintage\" combination tube and solid state amplifier from Dynaco.\u003c\/p\u003e\n\u003cp\u003eIncredible construction and attention to detail make these a match made in heaven - that’s why we are listing them together.

Capacitors are checked for telltale sings of bulging or leaking, resistors are checked for signs of overheating or cracking, and transistors are checked for signs of stress or damage. \u003cbr\u003e\u003cbr\u003eWe then power up the unit carefully and run a simple 1k sine wave while monitoring the output on an oscilloscope for signs of distortion or noise. Finally, we run the amplifier to its full rated power into the appropriate resistive load provided by our Sencore amplifier tester. If there is an issue, it will usually be noticeable at this point. If everything reads clean, we will often test for THD (Total Harmonic Distortion) measured by our Keithley distortion meter, and compare it against the original manufacturers specifications. The amplifier then remains powered on to \"burn in\" on our test bench for a few hours to make sure there are no heat related issues. If there are balanced inputs available they will be also be tested.\u003cbr\u003e\u003cbr\u003eFinal testing involves pushing actual music thorough the amplifier.

The tubes were carefully chosen—a pair of EF86 miniature pentodes for voltage gain and phase splitting (in a single stage), a pair of KT66 \"kinkless tetrodes\" for output power, and a GZ32 full-wave rectifier—and the output transformer was designed and made with painstaking care.”\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eOur Testing Process for Amplifiers (Tube) at SkyFi:\u003c\/strong\u003e\u003cbr\u003e\u003cbr\u003eWe start with a visual inspection of all internal components to make sure there are no signs of stress or aging.

Finally we run the amplifier to its full rated power into the appropriate resistive load provided by our Sencore amplifier tester. If there is an issue, it will usually be noticeable at this point. If it all looks clean we will often test for THD (Total Harmonic Distortion) measured by our Keithley distortion meter, and compare it against the original manufacturers specifications. The amplifier the remains powered on to \"burn in\" on our test bench for a few hours to make sure there are no heat related issues. If there are balanced inputs available they will also be tested.\u003cbr\u003e\u003cbr\u003eWe also test all tubes for output gain and leakage on our calibrated B\u0026amp;K 747 tester against the original manufacturers specifications.

Having worked at Bell Labs in engineering physics he had access to superb lab resources as well as lots of help from electronics engineers who had received their degrees during the golden age of tube electronics. It's obvious to me that Mark has learned his craft well. It starts with the monoblock layout. It's nearly impossible for me to accept an amplifier as Reference class unless it is of monoblock construction. Two totally independent and isolated power supplies and separate signal paths result in ideal channel separation and stable imaging under dynamic drive conditions.\u003c\/p\u003e\n\u003cp\u003eBoth the single-ended (RCA) and balanced (XLR) inputs are connected to a wide-bandwidth Jensen input transformer. Although it's strictly not necessary in the case of the RCA input, Mark believes that it does a neat job of eliminating potential ground loops and smoothing out the top end. One leg of the secondary is grounded, so that only the positive going portion of the balanced signal is used. The signal is then fed to a long-tailed pair phase inverter consisting of a 12AX7 dual triode. The driver stage is more sophisticated than what one typically sees in a 1950s vintage amp. It's a series-regulated push-pull circuit, also known as a Mu follower or totem pole, which uses a pair of 12AU7 dual triodes. The output stage is comprised of two pairs of KT88s operating in parallel push-pull configuration. The output transformers are quite beefy and feature an ultra linear connection. They use E-I laminate cores of grain-oriented silicon steel and are custom wound to a frequency response spec of 10 Hz to 50 kHz (+\/- 1dB). The windings are bifilar and are interleaved to reduced leakage inductance. The output stage mode may changed on the fly from UL to triode by the mere flick of a switch on the back panel. Of course, maximum output power is reduced by about one half in triode mode.\u003c\/p\u003e\n\u003cp\u003eInstead of the more common cathode bias, a fixed bias scheme is used. There are no cathode resistors, a dedicated –100 VDC bias supply is provided. This is a far more efficient biasing scheme than self bias since the entire B+ voltage is useable as plate voltage. A very nice touch is the built-in current meter. The quiescent current of each output tube may be adjusted individually using a set of pots located under a plate near the meter. A special tool is provided for that purpose. The entire process only takes a couple of minutes to complete if there are a few pots that need tweaking. Note that the bias is set on the low side at the factory as a precaution because it is a function of the AC main voltage. The recommended bias current is 40 mA and it should be set accurately only after each amp has been running for at least one hour. One knock against self bias is that it is not self-regulating as is cathode bias with tube aging. I found it necessary to tweak the bias a couple of time during the first week of use. After that, there was little drift; I would recommend a once-week bias check under heavy usage conditions and a bimonthly frequency for the average user.\u003c\/p\u003e\n\u003cp\u003eThe power supply is solid-state rectified and features voltage regulation for the front end preamp tubes. The other important feature, mandatory really, for a fixed-bias amp is the soft start circuit which ensures that high voltage is applied slowly while the bias supply kicks in. Each output tube is individually fused as an added safety feature to prevent runaway currents should the bias supply be interrupted.\u003c\/p\u003e\n\u003cp\u003eBoth 4 and 8-Ohm impedance taps are provided. These ratings should not be confused with the amp's internal source impedance which determines its damping factor. The source impedance is said to be about 0.4 Ohm — quite low for a tube amplifier with moderate levels of global feedback (about 18 dB) — and resulting in a damping factor of 20 into an 8-Ohm load. I'm so fed up with insulated EU style binding posts that look fancy but are difficult to tighten. Hence, it was really nice to see good old US style un-insulated posts of hexagonal profile that I can really tighten down on with a nut driver.\u003c\/p\u003e","brand":"Rogue Audio","offers":[{"title":"Default Title","offer_id":9388283559980,"sku":"Rogue Audio M-150","price":0.0,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0003\/3275\/9084\/files\/rogue-audio-m-150-tube-monoblock-amplifier-pair-844.jpg?v=1770325160"},{"product_id":"audio-research-d-110-classic-amplifier-in-perfect-condition-tested-and-certifier","title":"Audio Research D-110 Solid State Amplifier","description":"\u003cp\u003eIf you like late 70’s industrial design then you’ve found a perfect amplifier.\u003c\/p\u003e\n\u003cp\u003eProbably the most over built 110W amplifier I’ve seen.

Not just two separate signal paths in one box, but actually two completely separate unconnected boxes. One for each channel. It was common to have a two piece reference preamp, one housing the power supply and the other the preamp section - but a 4 box version was unheard of.\u003c\/p\u003e\n\u003cp\u003eIn addition, the KRS-1a uses the highest quality components available at the time. It is fully analogue without any complicated integrated circuits or proprietary components. This makes the unit super easy to service and likely to last for decades.\u003c\/p\u003e\n\u003cp\u003eWhen the unit arrived at our shop we quickly got to replacing every single capacitor in the preamp section. That is no small feat as there are over 120 capacitors. Unfortunately most capacitors will age, bulge, and leak over time and this unit showed some signs of it being a problem in the future. So, we went all out and replaced them all. We even serviced the phono boards.\u003c\/p\u003e\n\u003cp\u003eThis is a laborious and tedious endeavor but well worth the investment for a piece of audio history of this caliber and rarity. Do not buy a unit like this that has not been fully serviced as you will cringe when you get the bill for service. We used the highest quality Nichicon capacitors we could get our hands on.\u003c\/p\u003e\n\u003cp\u003eAs expected this unit comes with super high quality Krell phono modules internally installed. There are micro switches located on the boards that allow for no less than 10 loading values. There are also adjustments for a feature we have never seen before on a preamplifier. Internally you will find micro switches to select the correct type of CD player that is being connected. They call it a 3-pole phase correcting filter which is set to match the type of CD laser used in your unit like Phillips or Sony. Very cool option.\u003c\/p\u003e\n\u003cp\u003eAfter service the unit was thoroughly tested on the workbench before making its way into our dedicated listening room where it blew the doors off any preamp we have ever had the pleasure of using. Yes the dual volume adjustments take a bit more effort than a single potentiometer, but the extra trouble results in the best imaging and channel separation we have ever experienced.\u003c\/p\u003e\n\u003cp\u003eCosmetically the unit is in amazing shape considering the age. There are no noticeable or deep scratches or dents. There are a few light marks here and there but nothing worth mentioning and only visible upon very close inspection. All the writing and engraving is in perfect shape and there are no signs of use or abuse. The gold plated connectors are super clean and the knobs all operate precisely and responsively.\u003c\/p\u003e\n\u003cp\u003eDon’t miss the opportunity to own this piece of history sure to appreciate over time as more and more audiophiles realize the benefits of a full analogue preamp.\u003c\/p\u003e\n\u003cp\u003eIncluded are the 4 pieces as pictured, the two umbilical cords, two power cables, and original manual.\u003c\/p\u003e","brand":"Krell","offers":[{"title":"Default Title","offer_id":9388646793260,"sku":"Krell KRS-1a","price":0.0,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0003\/3275\/9084\/products\/krell-krs-1a-4-piece-reference-preamp-with-phono-module-preamplifier-139.jpg?v=1673888614"},{"product_id":"california-audio-labs-sigma-mkii-tube-dac-wonderfully-warm","title":"California Audio Labs Sigma mkII Tube DAC","description":"\u003cp\u003eThis little box was quite a unique piece when it hit the market as few companies made a highly acclaimed DAC with a tube output stage.

It has been designed to reproduce music as accurately as present day knowledge of acoustics and electronics permits. In addition to incorporating the 305mm (12in) bass driver with which AR introduced its acoustic suspension systems to home listeners, the AR-3a was the first speaker system to use two miniature hemispherical speakers developed by AR to give better midrange and high-frequency response. The new miniature speakers offer an unprecedented degree of accuracy in their respective ranges.\u003c\/i\u003e \u003c\/p\u003e\n\u003cp\u003e\u003ci\u003eThe design of such small speakers – one is only 19mm (3\/4 in) in diameter – although technically difficult, allows the laws of physics to operate to the listener´s advantage. While larger speakers must beam high frequencies straight forward, AR´s hemispheres instead spread these frequencies through a wide angle, considerably improving the realism of music reproduction for listeners in all parts of the room.\" \u003c\/i\u003e(Quote out of my old AR-Manual, 1970ies)\u003c\/p\u003e\n\u003cp\u003eAcoustic Research AR-3a

Finally, we run the amplifier to its full rated power into the appropriate resistive load provided by our Sencore amplifier tester. If there is an issue, it will usually be noticeable at this point. If everything reads clean, we will often test for THD (Total Harmonic Distortion) measured by our Keithley distortion meter, and compare it against the original manufacturers specifications. The amplifier then remains powered on to \"burn in\" on our test bench for a few hours to make sure there are no heat related issues. If there are balanced inputs available they will be also be tested.\u003cbr\u003e\u003cbr\u003eFinal testing involves pushing actual music thorough the amplifier.

Finally we run the amplifier to its full rated power into the appropriate resistive load provided by our Sencore amplifier tester. If there is an issue, it will usually be noticeable at this point. If it all looks clean we will often test for THD (Total Harmonic Distortion) measured by our Keithley distortion meter, and compare it against the original manufacturers specifications. The amplifier the remains powered on to \"burn in\" on our test bench for a few hours to make sure there are no heat related issues.

Finally we run the amplifier to its full rated power into the appropriate resistive load provided by our Sencore amplifier tester. If there is an issue, it will usually be noticeable at this point. If it all looks clean we will often test for THD (Total Harmonic Distortion) measured by our Keithley distortion meter, and compare it against the original manufacturers specifications. The amplifier the remains powered on to \"burn in\" on our test bench for a few hours to make sure there are no heat related issues. If there are balanced inputs available they will also be tested.\u003cbr\u003e\u003cbr\u003eWe also test all tubes for output gain and leakage on our calibrated B\u0026amp;K 747 tester against the original manufacturers specifications.

A new microprocessor controls all functions. The rear panel also includes a 12V trigger and a 15A IEC connector.\u003cbr\u003e\u003cbr\u003eThe LS27 is a pure Class-A design with zero feedback, and the massive power supply is fully regulated. Gain is provided by twin 6H30 triodes.

Capacitors are checked for telltale sings of bulging or leaking, resistors are checked for signs of overheating or cracking, and transistors are checked for signs of stress or damage. Special attention is paid to the power supply which is the most common source of failure for preamps.

This 'Double-Star Quad' cable doesn't look normal on the outside, and it isn't normal on the inside, either. AudioQuest Rocket 88 offers amazingly clean and effortless performance, thanks to a combination of extraordinary materials and extremely refined design.\u003cbr\u003e\u003cbr\u003e\u003cstrong\u003eDielectric Bias System (DBS)\u003c\/strong\u003e\u003cbr\u003eGreatly improved performance is made possible by a constant 72 volt charge on all Rocket 88's insulation. Similar to how the earth's magnetic field makes all compasses point north, the AQ DBS system creates an electrostatic field which causes the molecules of the insulation to all point in the same direction. This minimizes the multiple nonlinear time-delays. Sound appears from a surprisingly black background with unexpected detail and dynamic contrast.\u003cbr\u003e\u003cbr\u003eBecause DBS battery packs are attached when Rocket 88 cables are assembled, Rocket 88 does not require any additional run-in period. Because there is no \"load\" on the easily replaceable batteries, they will last for years. A test button and LED allow for occasional verification of battery performance.\u003cbr\u003e\u003cbr\u003e\u003cstrong\u003eSolid Conductors\u003c\/strong\u003e\u003cbr\u003eAll eight of Rocket 88's conductors are solid. Solid conductors prevent strand interaction, a major source of cable distortion. Electrical and magnetic interaction between strands in a conventional cable is the single greatest source of distortion, often causing a somewhat harsh, dirty and confused sound.\u003cbr\u003e\u003cbr\u003eSolid conductors are the most important ingredients enabling Rocket 88's very clear sound. Whether a conductor is solid or stranded, skin effect is a prime distortion mechanism in speaker cables. Rocket 88 very simply keeps this effect out of the audio range by using conductor sizes that are below the threshold for audible distortion.\u003cbr\u003e\u003cbr\u003e\u003cstrong\u003eExtreme High-Purity Perfect-Surface Copper\u003c\/strong\u003e\u003cbr\u003eExtreme high-purity Perfect-Surface Copper (PSC) minimizes distortion caused by grain boundaries that exist within any metal conductor, eliminating harshness and greatly increasing clarity compared to all other conducting materials. PSS has an astonishingly smooth and pure surface. Proprietary metal processing technology protects the wire's surface at every stage of drawing and fabrication. When high-purity low-oxide copper is kept as soft, pure and smooth as possible, it becomes the wonderfully low distortion PSC conductor used in many AudioQuest models. PSC's extreme transparency is made possible by applying Perfect Surface Technology to ultra pure solid copper. PSC is the ultimate example of how far this remarkable technology can take us.\u003cbr\u003e\u003cbr\u003e\u003cstrong\u003eSpread Spectrum Technology (SST)\u003c\/strong\u003e\u003cbr\u003eAny single size or shape of conductor has a characteristic distortion profile. Even though radially symmetrical conductors (solid round or tubular) have the fewest discontinuities, each size still has a sonic signature. Rocket 88 uses a precise combination of four different size conductors in order to significantly reduce the audibility of these character flaws.\u003cbr\u003e\u003cbr\u003e\u003cstrong\u003eDouble Star-Quad Geometry\u003c\/strong\u003e\u003cbr\u003eThe relationship between conductors defines a cable's most basic electrical values (capacitance and inductance). However, even when those variables are kept in a reasonable balance, the relationship between conductors can be varied in ways that greatly affect the sound. The Double Star-Quad construction of Rocket 88 allows for significantly better dynamic contrast and information intelligibility than if the same conductors were run in parallel.\u003cbr\u003e\u003cbr\u003eThe specific 4-cross geometry used in each half of Rocket 88 maximizes this advantage. In addition, Rocket 88 is an exceptional Single-BiWire cable. When the halves are separated at the speaker end, the Double StarQuad design turns Rocket 88 into a true Double-BiWire set thanks to the magnetic autonomy of each star-quad. When separated the Dual Star-Quads let Rocket 88 be a maximum performance Double-BiWire in a single cable.\u003cbr\u003e\u003cbr\u003e\u003cstrong\u003eCold-Weld Terminations\u003c\/strong\u003e\u003cbr\u003eSuperior AudioQuest connectors allow Rocket 88 to be securely attached to any type of equipment. AQ ends are dull looking because there is no harsh sounding shiny nickel layer underneath the silver (or gold). The connection between the plug and conductors is made using AQ's Cold-Weld system which provides a superior connection that ensures that the structural integrity of the conductor is kept completely intact.\u003cbr\u003e\u003cbr\u003eA controlled amount of pressure is used to essentially make the conductor and connector mechanically \"as one\" without the use of heat. The copper bearing paste acts as both a copper oxide retardant, and as well as a very effective contact enhancer.

The midrange\/tweeter head is electrically connected with the lower cabinet via a short umbilical and an XLR connector, and is secured b y a very long bolt that runs completely through the head, down into the bass enclosure. There are two sets of speaker terminal connectors on the bottom rear of the bass cabinet, in order to allow the listener to bi- wire the speakers (these connectors are normally internally bridged, so in order to bi-wire, the bottom cover under the bass cabinet must be removed, and two very short jumpers removed...a less-than-ideal setup).\u003cbr\u003e\u003cbr\u003eThe cabinet construction is excellent, showing a great deal of attention to assembly and aesthetic detail, except for the quality of the speaker terminal connectors. Rather than utilizing standard five-way binding posts (as B\u0026amp;W does with their less expensive 802 speakers), they have opted. for some rather poor-quality, screw-type terminals that just don't belong on a product of this quality. Except for the round port vented on the front of the bass cabinet directly below the woofer, the new Matrix 801 is visibly similar to its predecessor. The casters mounted on the bottom are nice to have when moving these behemoths around the house or studio. But since the speakers really need to be placed on stands in order to operate at full potential, this otherwise practical addition is somewhat useless.\u003cbr\u003e\u003cbr\u003eThe internal design and components represent a clear departure from the earlier 801. By using their effective Matrix technology of incorporating an internal system of honeycombs within the bass cabinet, the engineers at B\u0026amp;W claim to have reduced low-frequency enclosure resonances and colorations to a significant degree (I agree). Additionally, but using a sixth-order Butterworth alignment through the addition of an outboard equalizer, they have been able to achieve extraordinary low-frequency response (-6dB at 17.5Hz) without compromising bass attack and clarity. Although the speaker can operate without this optional equalizer (thereby effectively representing a fourth-order Bessel filter with a -9dB point at 19Hz), the addition of this device clearly enhances its overall musical accuracy.\u003cbr\u003e\u003cbr\u003eThe midrange fibercrete head assembly and Kevlar-coned driver remain basically unchanged from the earlier 801. The high-frequency driver (the TS26 tweeter), on the other hand, represents an entirely new design, incorporating a metal-domed diaphragm. This design was arrived at partially through B\u0026amp;W's computer-aided design (CAD), and is a modified version of the metal-dome tweeter used in the less costly Concept 90 series of loudspeakers. B\u0026amp;W claims that this new tweeter \"exhibits perfect piston-like behavior to frequencies well beyond audibility.\" The newly redesigned bass driver has a cone of specially formulated plastic compound, is heavily damped to remove sonic colorations, and employs a 13lb, 13,000 Gauss magnet.\u003cbr\u003e\u003cbr\u003eIn order to protect the drivers from over load, B\u0026amp;W has upgraded the already existing Audio-Powered Overload Circuit (APOC) by incorporating two such units: one operates on the bass section, the other on the midrange! tweeter, allowing complete protection even when the system is bi-wired.\u003c\/p\u003e","brand":"SkyFi Audio","offers":[{"title":"Default Title","offer_id":9527894278188,"sku":"B\u0026W Matrix 801 Series 2","price":0.0,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0003\/3275\/9084\/files\/b-w-bowers-wilkins-matrix-801-series-2-speakers-524.jpg?v=1770235151"},{"product_id":"balanced-audio-technology-vk-250-solid-state-amplifier-250w","title":"Balanced Audio Technology VK-250 Solid State Amplifier, 250W","description":"\u003cp\u003eCosmetically this 250W amplifier looks brand new and will not disappoint even the pickiest of buyers.
