FOR SALE: On pair of PASS LABS ALEPH 2 amplifiers.

Visually, there are in nice shape with multiple TINY blemishes on them. They look good.

Operationally, the sound sensational, and possibly closer to a tube amp than any solid state amp I have heard recently.

They are also quite powerful.

They are rated for 100 Watts each into 8-Ohms and 200 Watts each into 4-Ohms, and they sound even more powerful than that.

They are very compact, at about 12-inches on all sides, so they are easy to place near speakers, if you want.

They do run very hot, being Class-A MOSFET in design, but the massive heat-sinking keeps the transistors within their safe operational area.

Someone who wants most of the sound of tubes, combined with fairly high power and massive current capability for great, tight bass, will be very happy with these.

When new, these sold for about $6800/pr. That was a bargain, in my opinion!

THE RESERVE IS $2188.00 for the pair.

• The following is from the owner’s manual…
  

The Aleph 2 is the second of the newest generation of amplifiers from Pass Labs. This design results from my commitment to create the best sounding product, a simple circuit having the most natural characteristic. The Aleph 2 integrates power Mosfet devices and pure single ended Class A operation in a simple two-gain-stage topology with the sole purpose of recreating subjectively natural sound.

The Aleph 2 is unique in a number of ways:

Unlike the earlier Aleph amplifiers, it operates in pure single-ended mode over its entire operating region, and does not incorporate a “pull” stage for additional current beyond its bias point. When the single-ended output Mosfets (six in parallel) reach cutoff, the amplifier clips.

Most amplifiers on the market have between five and seven gain stages in series between the input and the output. The Aleph 2 has but two, and enjoys a very direct path from input to output, further enhancing the purity of the circuit and the resulting sound. Earlier Aleph amplifiers have three gain stages.

The output stage of the Aleph 2 is a unique blend of traditional design and innovation addressing the unique requirements of loudspeakers. Previous methods of loading the output stage have used networks consisting of resistors, coils, transformers, and active current sources, all of which offer an optimal load line based on a resistive load. The Aleph 2 has a current source topology which optimizes performance for a wide range of impedance and reactance in the load, improving all aspects of performance into real loudspeakers. Pass Labs has a US patent pending on this output stage topology.

The Aleph 2 is unique in that there are no adjustments of any kind in the circuitry. There are no potentiometers to adjust. The operating parameters of bias currents and DC offset and so on are defined by physical constants, and will not go out of adjustment.

Most important, the Aleph 2 brings a new dimension to the recreation of subjective sonic reality. The amplifier delivers detail and subjective space rarely found in semiconductor circuits, coupled with the authority and clarity rarely found in tube amplifiers.
