VK-P12 uses the same amorphous core output transformers employed throughout Balanced Audio Technology’s premier line of phonostages Complementing the unit’s all-tube zero-feedback design, a unique Flying RIAA circuit maximizes accuracy, brings the benefits of fully differential operation to the critical equalization stage, and delivers standard-bearing fidelity to the original recorded signal.\u003cbr data-mce-fragment=\"1\"\u003e\u003cbr data-mce-fragment=\"1\"\u003e\u003cspan style=\"text-decoration: underline;\"\u003eBALANCED ARCHITECTURE\u003c\/span\u003e\u003cbr data-mce-fragment=\"1\"\u003eThe VK-P12 is fully balanced from input to output. For the best possible performance, the phono cartridge should be used in a matching balanced configuration. Many turntables and tonearms allow for such a termination. In some cases, even if only RCA connectors are present on the arm, the cartridge can still be used in a balanced configuration by using a specially designed cable.\u003cbr data-mce-fragment=\"1\"\u003e\u003cbr data-mce-fragment=\"1\"\u003e\u003cspan style=\"text-decoration: underline;\"\u003eTEN-TUBE, ZERO-FEEDBACK DESIGN\u003c\/span\u003e\u003cbr data-mce-fragment=\"1\"\u003eThe VK-P12 features an all-tube zero-feedback design that combines the benefits of balanced operation with complementary vacuum-tube current sources. Dual-mono construction and enormous energy reserves are matched by extensive flexibility in cartridge loading. Equipped with a new aluminum top cover, this incredible music instrument boasts high-quality input step- up transformers for greater flexibility in handling the lowest-output moving-coil cartridges as well as a Six-Pak of custom oil-filled capacitors in the output stage.\u003cbr data-mce-fragment=\"1\"\u003e\u003cbr data-mce-fragment=\"1\"\u003e\u003cspan style=\"text-decoration: underline;\"\u003eFLYING RIAA NETWORK\u003c\/span\u003e\u003cbr data-mce-fragment=\"1\"\u003eAmong the benefits of the VK-P12’s differential RIAA network are ease of adjustment and improved common mode noise rejection. This circuit is also completely passive and has fewer components than a more traditional implementation. The ease of factory adjustment translates into improved matching of the RIAA curve to specification, with an RIAA error typically not exceeding 0.1dB! With the BAT Flying RIAA network, you can be assured that all of your records sound the way that the recording engineer intended.\u003cbr data-mce-fragment=\"1\"\u003e\u003cbr data-mce-fragment=\"1\"\u003e\u003cspan style=\"text-decoration: underline;\"\u003eVACUUM-TUBE CURRENT SOURCES\u003c\/span\u003e\u003cbr data-mce-fragment=\"1\"\u003eVacuum-tube current sources further improve the linearity of any gain stage to yield a more open and textured sound than a simple resistor-based solution. In the VK-P12, dual 6SN7 vacuum tubes act as current sources for the second gain stage. They complement the inherent strength of vinyl playback in that the finest texture and harmonic structure of musical instruments are portrayed with greater delicacy.\u003cbr data-mce-fragment=\"1\"\u003e\u003cbr data-mce-fragment=\"1\"\u003e\u003cspan style=\"text-decoration: underline;\"\u003eSELECTABLE STEP-UP TRANSFORMERS\u003c\/span\u003e\u003cbr data-mce-fragment=\"1\"\u003eThe VK-P12 features second-generation step-up transformers that provide as much as a 20dB improvement in signal-to-noise ratio in comparison to direct mode operation. This allows the customer to successfully use even the lowest output moving-coil cartridges. With up to 80dB of gain available, no signal is too small!\u003cbr data-mce-fragment=\"1\"\u003e\u003cbr data-mce-fragment=\"1\"\u003e\u003cspan style=\"text-decoration: underline;\"\u003eSUMMARY\u003c\/span\u003e\u003cbr data-mce-fragment=\"1\"\u003eThe whole of the engineering of the VK-P12 is greater than the sum of its parts. Such synergy will pay countless dividends on your investment in vinyl. And, of course, all VK-P12 phonostages can be further upgraded to VK-P12SE or VK-P12SE SuperPak status, maintaining the commitment to a rational upgrade path that has earned BAT tremendous customer loyalty.\u003cbr data-mce-fragment=\"1\"\u003e\u003c\/p\u003e\n\u003cp data-mce-fragment=\"1\"\u003e\u003ca title=\"BAT (Balanced Audio Technology) VK-P12 - Sales Brochure on SkyFi Audio\" href=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0003\/3275\/9084\/files\/BAT-VK-P12-Sales-Brochure.pdf?v=1596764953\" data-mce-fragment=\"1\" target=\"_blank\" data-mce-href=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0003\/3275\/9084\/files\/BAT-VK-P12-Sales-Brochure.pdf?v=1596764953\"\u003eBAT (Balanced Audio Technology) VK-P12 - Sales Brochure\u003c\/a\u003e\u003c\/p\u003e\n\u003cp data-mce-fragment=\"1\"\u003e\u003ca title=\"BAT (Balanced Audio Technology) VK-P12 - Owners Manual on SkyFi Audio\" href=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0003\/3275\/9084\/files\/BAT-VK-P12-Owners-Manual.pdf?v=1596764953\" data-mce-fragment=\"1\" target=\"_blank\" data-mce-href=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0003\/3275\/9084\/files\/BAT-VK-P12-Owners-Manual.pdf?v=1596764953\"\u003eBAT (Balanced Audio Technology) VK-P12 - Owners Manual\u003c\/a\u003e\u003c\/p\u003e\n\u003cp data-mce-fragment=\"1\"\u003e\u003cstrong data-mce-fragment=\"1\"\u003eThe SkyFi Testing Process for Preamplifiers (All):\u003c\/strong\u003e\u003cbr data-mce-fragment=\"1\"\u003eWe start with a visual inspection of all internal components to make sure there are no signs of stress or aging. 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. We then power up the unit and run a simple 1k sine wave while monitoring the low voltage output on an oscilloscope for signs of distortion or noise to get a baseline. \u003cbr data-mce-fragment=\"1\"\u003e\u003cbr data-mce-fragment=\"1\"\u003eAt this point we will lubricate and clean all switches and potentiometers (that are not sealed) with a high quality contact cleaner, and then re-test all functions for any signs of noise or scratching. \u003cbr data-mce-fragment=\"1\"\u003e\u003cbr data-mce-fragment=\"1\"\u003eFinal testing involves putting actual music through the preamplifier We have learned over time that some issues are only noticeable to a trained ear while listening to a familiar source material. Our test bench has reference vintage KEF speakers that we are super familiar with which will quickly reveal any discrepancies. Some preamps will then move into the listening room where they will be tested with our in-house reference system.\u003c\/p\u003e\n\u003cp\u003e\u003cb\u003eThe SkyFi Testing Process for Preamplifiers:\u003c\/b\u003e\u003c\/p\u003e\n\u003cp\u003eWe start with a visual inspection of all internal components to make sure that there are no signs of heat stress or damage. Capacitors are checked for telltale signs of predictive failure including bulging, shrunken wrappers, or physical leakage. We also inspect the PCBs for discoloration from resistors or transistors that may have been running hot. On vintage units we often spot check select capacitors for value and ESR.\u003c\/p\u003e\n\u003cp\u003eWhen we first power on a preamplifier we connect its RCA output to a Sencore PA81 Power Analyzer which simulates real world loading conditions and gives us an oscilloscope interface. The first order of business is checking that the volume control works smoothly throughout its entire range with acceptable channel balance. This is accomplished by feeding a 1KHz sine wave into one of the preamp’s line level inputs while monitoring the preamp’s output on an oscilloscope. We then switch to a 1KHz square wave to test the tone controls, loudness function, and filters where applicable. During this step we are watching for equal alteration of the test signal by both channels. This also helps us identify dirty controls that will need treatment. Once the basic line stage functions are verified, we test each input individually. This is especially important for devices that use relays to select their sources. If the preamp is equipped with a phono stage we test that as well. We use an inverse RIAA filter which allows us to feed a reference test signal into the phono input with the proper RIAA equalization and level. A square wave or sine sweep is used to verify that the device’s phono stage is faithfully reproducing the RIAA curve. If the preamp under test has balanced inputs and\/or outputs these are tested as well.\u003c\/p\u003e\n\u003cp\u003eWe finish up our bench testing with a listening test with our bench amplifier and reference speakers. During this test we check for hum or hiss that may not have shown up in earlier testing. We also check that all of the tone controls and filters perform as expected. If the preamplifier has remote control functions these are also tested.

These are ‘passive” components (like resistors, capacitors and inductors) as well as ‘active’ ones, in this case, transistors. The opposite of this would be an integrated circuit with operational amplifiers (op-amps) in the signal chain. Countless hours worth of listening tests and years of experience have shown us how to make a neutral, natural, dynamic, and vivid sound. Standard phono pre-amplifiers with integrated circuits have tens or hundreds of components, but discrete designs employ hundreds or thousands of components by comparison. That makes for an extended and more costly design process but results in the best sound for your money.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eFully Balanced\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003ePhono Box RS2 employs a true fully balanced design principle.

A truly balanced amplifier can now extract the final musical information out of the +\/- signals and subtract (remove) all noise that could potentially be added along with the transmission. In a true, fully balanced amplifier like Phono Box RS2, the + and – sections of both the left and right channels are treated individually, which doubles the amplifier sections as a result.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eSplit Passive EQ\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003ePhono Box RS2 uses split passive equalization for both its RIAA and DECCA curves.

Split passive equalization allows for better impedance matching and lower deviation from the ideal RIAA or DECCA curve.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eNumerous Cartridge Loading Options\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eNo other phono preamp in the world offers the gain flexibility of Phono Box RS2. A huge range from 40dB (voltage amplification by 100x) up to 70dB (voltage amplification by 3690x) is possible. Load impedance can be set on the fly via a potentiometer – a system invented by Pro-Ject Audio Systems. It allows you to seamlessly adjust impedance during playback and immediately assess the impact of various loading options. By nature, cartridges suffer from small imbalances between the left and right channels. To correct this, Phono Box RS2 also introduces a new feature that is rare in this price category. A potentiometer allows you to adjust to the exact center of the sound stage in a range of 2dB to the left or right.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eSteel\/Aluminium Chassis\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eThe Phono Box RS2 has a steel chassis that is covered by aluminum panels.

Its upgrades include circuit enhancements originally developed for the acclaimed TL-7.5 Series III Reference Preamplifier, as well as newly designed, more robust power storage for the active MC stage.\u003cbr\u003e\u003cbr\u003eThe original TP-6.5 Phono preamplifier complemented the top of the line VTL TL-6.5 and TL7.5 Linestage Preamplifiers, matching them in sonic performance, user interface and cosmetics. The new TP-6.5II pushes the analog envelope even further, utilizing the latest innovations from VTL. The result is a phono stage that substantially improves upon the performance of its predecessor.\u003cbr\u003e\u003cbr\u003eThe phono stage employs hybrid JFET\/tube circuitry for quiet operation, multiple low-noise cascaded regulators and shielded power supplies for increased dynamics, accurate 4-corner passive RIAA equalization and 68dB of gain from the balanced outputs, all in a single chassis unit. A wide selection of load and gain settings as well as other input functions are easily accessible via both front panel and remote control.\u003cbr\u003e\u003cbr\u003eOne of the design breakthroughs in the TP-6.5 II is the use of the shunt regulator in the power supply, which offers superior regulation and ripple rejection and minimizes the sonic impact on the audio signal due to lowered amplification in the regulator. The result is a noticeable lowering of background noise contributing to stability and better delineation of midrange and midbass. There is more air around the voices, more finesse, extension, and nuances – giving an overall more lifelike impression. Especially noticeable improvement in the active MC Stage is its speed and dynamics.\u003cbr\u003e\u003cbr\u003eFurther improvement in the TP-6.5 Series II comes from the implementation of massive low impedance power supply storage in the active MC stage, fed by multiple cascaded regulators and capacitance multiplier circuits. The resulting rigid, low impedance power supplies prevent power supply ripple and other noise from affecting the sensitive MC signal. The new gel capacitor technology, which offers dramatically higher capacitance in much smaller packages, is key to the breakthrough in the TP6.5 II’s active MC stage directly contributing to its remarkable lower noise level and ability to handle very low output cartridges.\u003cbr\u003e\u003cbr\u003eThe TP-6.5II also offers a high quality transformer Moving Coil step up option, both to offer a low-noise MC step up, and a second MC stage. This second MC input replaces the original MM input that is normally standard in the TP6.5 Phono Stage, and uses the existing MM input to provide access to the transformer MC step up.\u003cbr\u003e\u003cbr\u003eThe addition of the step up transformer allows both for appropriate loading for very low-output cartridges, and the flexibility of handling different cartridges with different step up methods, as in some cases certain cartridges can sound substantially better with transformers than they do with active gain stages. The transformer also allows the cartridge to be loaded via the transformer, instead of via the loading resistor, retaining as much of the signal available from these cartridges as possible.\u003cbr\u003e\u003cbr\u003eSwitching between the inputs is done only after the signal has been amplified, avoiding signal losses inherent in switching the fragile MC signal straight from the cartridge.\u003cbr\u003e\u003cbr\u003eThis option offers the maximum MC cartridge handling flexibility, and also accommodates multiple arms and multiple MC cartridges, as both inputs can be connected simultaneously.\u003c\/p\u003e\n\u003cp\u003e\u003cmeta charset=\"utf-8\"\u003e\u003cb\u003eMSRP:\u003c\/b\u003e\u003cbr\u003e$18,000\u003c\/p\u003e\n\u003cp\u003e\u003cb\u003eSkyFi Cosmetic Notes:\u003c\/b\u003e\u003cbr\u003eSome light scratches on the chassis, overall good.\u003cbr\u003e\u003cbr\u003e\u003cb\u003eSkyFi Technical Notes:\u003c\/b\u003e\u003cbr\u003eThe MC phono input is loaded with two NOS RFT 12AU7 tubes.

Capacitors are checked for telltale signs of predictive failure including bulging, shrunken wrappers, or physical leakage. We also inspect the PCBs for discoloration from resistors or transistors that may have been running hot. On vintage units we often spot check select capacitors for value and ESR. \u003cbr\u003e\u003cbr\u003eWhen we first power on a preamplifier we connect its RCA output to a Sencore PA81 Power Analyzer which simulates real world loading conditions and gives us an oscilloscope interface.\u003cbr\u003e\u003cbr\u003eThe first order of business is checking that the volume control works smoothly throughout its entire range with acceptable channel balance. This is accomplished by feeding a 1 KHz sine wave into one of the preamp’s line level inputs while monitoring the preamp’s output on an oscilloscope.\u003cbr\u003e\u003cbr\u003eWe then switch to a 1 KHz square wave to test the tone controls, loudness function, and filters where applicable. During this step we are watching for equal alteration of the test signal by both channels. This also helps us identify dirty controls that will need treatment.\u003cbr\u003e\u003cbr\u003eOnce the basic line stage functions are verified, we test each input individually. This is especially important for devices that use relays to select their sources. If the preamp is equipped with a phono stage we test that as well. We use an inverse RIAA filter which allows us to feed a reference test signal into the phono input with the proper RIAA equalization and level. A square wave or sine sweep is used to verify that the device’s phono stage is faithfully reproducing the RIAA curve. If the preamp under test has balanced inputs and\/or outputs these are tested as well.\u003cbr\u003e\u003cbr\u003eWe finish up our bench testing with a listening test with our bench amplifier and reference speakers. During this test we check for hum or hiss that may not have shown up in earlier testing. We also check that all of the tone controls and filters perform as expected.\u003cbr\u003e\u003cbr\u003eIf the preamplifier has remote control functions these are also tested. Preamps with tube circuits or complicated power supply topologies are connected at our long term test rig for extended stress testing under real world conditions.\u003c\/p\u003e","brand":"VTL","offers":[{"title":"Default Title","offer_id":46996087111934,"sku":"106664","price":11990.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0003\/3275\/9084\/files\/vtl-tp-6-5-series-ii-signature-hybrid-tube-phono-preamplifier-complete-set-with-upgrades-136.jpg?v=1753470379"},{"product_id":"leben-rs-30eq-mm-moving-magnet-phono-preamplifier-new-pre-order","title":"Leben RS-30EQ MM (Moving-Magnet) Phono Preamplifier - New - Pre-Order","description":"\u003ch5\u003eSKYFI IS NOW A LEBEN DEALER\u003cmeta charset=\"UTF-8\"\u003e\n\u003c\/h5\u003e\n\u003cdiv class=\"feature-list\"\u003e\n\u003cp class=\"feature-detail\"\u003eThe Leben RS-30EQ is a beautiful tube phono preamplifier.
