I have owned the Classe CAD-200 for just under a year as an original owner in a smoke and pet free environment. It has served me well and sonically exceptional. Classe is one of the finest sounding amplifier as compared to other class Ds that are out there. It is on top my list. It will drive virtually most speakers on the market. In original box, packaging, papers and accessories.
Priced to go.

Excerpt from TAS: Sonically the CP-800/CA-D200 combo has a character that admirers of top-notch solid-state will immediately cozy up to: tight, crisp, tuneful bass response, a well-proportioned midrange, and a top end that seems to extend skyward. Perhaps its greatest strength is just how clean and fast and focused even the smallest musical transitions that it conveys are. The entrances and exits of individual notes emerge and recede into the recording venue’s inky black silences, pure and unfettered by noise or coloration. Whether it’s a churning beat from a high-hat or the distant slap-rattle of a tambourine, or the articulation of a lightning-fast series of notes coming off a concert grand, the Classé is as sure-footed and nimble as they come. The same traits apply to the low-level transparency of, say, the soft string arpeggios from a concert harp, or the steely peal of a percussionist’s triangle.
CA-D200 200W TWO-CHANNEL AMPLIFIER
The CA-D200 is a new and innovative amplifier design that uses what
are called switching technologies. Switching amplifiers and power
supplies offer many advantages but present different challenges and a
higher degree of complexity than conventional linear designs. Their
potential is too great to ignore, however, which is why the Classé
Design team now includes engineers with over fifty years combined
experience in switching amplifier and power supply design. The result is
the CA-D200, the first of its type from Classé; the first of its
Switching Power Supply
A new Switch Mode Power Supply with Power Factor Correction, provides
over 1,000W of clean, stable power to the CA-D200 amplifier circuitry.
The SMPS and PFC each operate at over 90% efficiency, yielding
impressive benefits for power delivery. The low frequency dynamics,
extension and control of the CA-D200 and its ability to effortlessly
drive difficult speaker loads can be credited in large part to the
powerful and sophisticated power supply it employs. The SMPS with PFC is
ideally suited to the demands of the CA-D200’s revolutionary switching
Some technical limitations have been commonly accepted as inherent in
switching amplifiers—until now. Perhaps the biggest limitation is called
dead-band time, which translates directly to distortion and tempts
designers to employ excessive amounts of negative feedback to
compensate. With its proprietary drivers and DSP tools, the Classé
Design team solves the dead-band time problem with precision and
consistency for each and every CA-D200. On power up, controller
circuitry analyzes and adjusts to minimize the dead-band time for each
pair of outputs. In this way, part tolerances and drift for each
individual amplifier are taken into account. Lastly, the feedback loop
is closed using the least amount of negative feedback required. Our
linear phase output filters are then employed only to filter the 384 kHz
switching frequency, not to roll off the top end of the audio band, as
is often done to try to make amplifiers with high dead-band time more
listenable. The result is a wide and deep soundstage with extended high
frequencies that reveal a musically detailed and open midrange and top
The CA-D200 employs proprietary component parts and DSP technology along
with sound engineering practice to optimize its sonic performance at an
