Classe CA-D200 Delta Series Stereo Power 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 type—period.

Product Description

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
amplifier topology.

Switching Amplifier

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 feed
-back 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 end.


The CA-D200 employs proprietary component parts and
DSP technology along with sound engineering practice
to optimize its sonic performance at an affordable price
of admission for a Classé amplifier. Listen and hear for
yourself how beautiful great value can sound.
