Many amps have been in my system (VTL, Simaudio, Krell), but
the Classe Omegas are the best I’ve owned. They offer an amazing balance of utter
power, resolution, delicacy, neutrality along with the convenience of solid
state. They include a pair of manuals and the original Cardas Golden power
cords (8-ft). Only a blemish on one face plate that is not easily recognizable
until close examination.

SPECS:

Solid-state monoblock power amplifier with unbalanced (RCA)
and balanced (XLR) inputs and two pairs of 4mm output binding posts. Rated
output power: 500W into 8 ohms, 1000W into 4 ohms, 2000W into 2 ohms, 4000W
into 1 ohm (all 27.0dBW). Sensitivity: 2.25V for rated output, balanced or
unbalanced. Voltage gain: 29.0dB. Input impedance: 100k ohms. Output impedance:
0.017 ohm. Frequency response: 20Hz-2kHz, ±0.1dB. THD+noise: 0.002%. S/N Ratio:
135dB ref. rated output.

Stereophile REVIEW SUMMARY:

The Classé Omega monoblock is an extraordinary
amplifier—extraordinary in its appearance, its engineering and construction,
and, most of all, in its sonic performance. But despite its over-the-top power
and energy reserves, it is in the handling of details that the Omega is most
impressive. However, in spite of the apparent incongruity, I think that it is
precisely because of the Omega's prodigious power, and its ability to precisely
control a speaker's motion, that it could do such an incredible job with the
subtleties. Prior to the Omegas' arrival, my system's tiniest details had been
lost in the slight blurring that arose from the speakers not quite keeping up,
or in the faint overhang and back EMF resulting from the drivers' momentum overmatching
the amplifier.

The Classé Omega is not only the best power amplifier I've
ever auditioned, but in many ways it exceeded my ability to evaluate it—I found
myself instead evaluating associated components, setup details, the system's
response to changes in the weather, even characteristics of a recording itself.
The Omega simply got out of the way, providing a clear conduit, a straight wire
with gain—a lot of gain—between my system's front-end and loudspeakers. And
because of its ability to absolutely control a loudspeaker, a finer level of
detail was able to pass through this conduit than through most other
amplifiers. The result, for me, was a level of system performance and musical
involvement beyond my previous experience.

Excellent working condition, tested before listing, sound
fantastic. Serials numbers 1300173 & 1300182. Photos show actual items for
sale. Serious inquiries only please. Local pickup available. If shipped will be
shipped in custom foam lined crates fully insured. These amps were two of some
30 monoblocks owned by the billionaire

These are widely recognized as the best amplifiers Classe
ever built. They don't come up for sale very often - they're so good owners
rarely sell them. I’m selling to downsize and buy an apartment in Germany. Classe
made improvements over time without changing the name, model number, or
appearance - this pair of Omega Monos is the most recent and best sounding
version which have the CAN Bus and related features that were also included in
the Delta series.

 

I’m the 2nd owner (Nov 2018), having bought them
from the estate of Darryl Ellis Rubin, the original owner (2004). They were
minimally used by him as they were in a guest room of a massive mansion and he
had multiple audio setups. Literally he had purchased some 30 monos. Purchased
from the Pacific Northwest’s premiere dealer (Definitive Audio). Maintained in
a smoke-free and pet-free climate controlled environment.  I’ve used it infrequently, also being the
owner of several setups.

Shipping arrangements will be made after sale. These amps
are large and HEAVY (230lbs each in shipping cases). Freight with lift gate
service is recommended. Paypal or Bank wire are the preferred methods of
payment. Paypal will add 3%. Purchased items will have a handling time of up to
3 business days from time of cleared payment.

Power supply regulation: 
The Omega Mono has the most substantial and sophisticated power supply
regulation of any Classé product to date. 32 bi-polar transistors (the same
quantity and type as the audio output transistors) are bolted onto a colossal
heat sink. These transistors form the basis of the power supply regulation circuit
and provide a totally stable supply for all the sections of the power
amplifier. When reproducing powerful energy such as deep organ notes or driving
bass, the power drain on a conventional system can be great enough to starve
other parts of the audio circuit. However, in the Omega Mono power supply, even
under the worst possible conditions, the voltage can only drop by one volt. As
the audio circuits under full power never call for maximum power supply
voltage, the result is a totally stable supply to all the audio circuits under
all operating conditions.

Circuit board:  The
circuit boards are constructed from four bonded layers of epoxy resin,
achieving an extremely strong, rigid and non-resonant foundation for the audio
components. This construction keeps the signal path very short with the added
benefit of containing the signal track within the sandwich of layers and
preventing the ground plane from picking up any noise.
