Mark Levinson No. 23 Vintage Dual Mono Stereo Amplifier - 200W!

$3,599

Wonderful amplifier from Mark Levinson's golden era when they were at their highest quality, craftsmanship, and musicality.  

This incredibly built amplifier is in amazing condition and came to us from the original owner who took amazing care of it. 

There isn't a single noticeable scratch or ding which is hard to do in an amplifier of this weight. Moving a heavy amplifier around often results in a slight scratch or broken toe.  

On the bench this piece passed with flying colors. There we no indications of leaking capacitors or under performing components. 

The back features both balanced inputs and CAMAC inputs, which are a more sophisticated version of an RCA jack.

In case you don't have a matching ML preamp, we have some CAMAC adapters available for purchase separately. They're not included in this listing so please contact us before your purchase if you'd like to add.

Ideally however this amp would be connected with balanced cables for best performance, removing the need for the CAMAC adapters.

You'll also find a standard set of speaker terminals, plus removable electrical plugs and fuses for each channel reflecting its true dual monaural amp status.

200W of output will allow you to power most speakers, vintage and modern, with authority and ease.

The SkyFi Testing Process for Solid State Amplifiers:
We 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.

We 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.

Final testing involves pushing actual music thorough the amplifier. We've learned over time that some issues are only noticeable to a trained ear while listening to familiar source material. Our test bench has reference vintage KEF speakers that we're very familiar with which quickly reveal any discrepancies. Some amplifiers will then move into our listening room where they are tested with our in-house reference speakers of choice.
