Classé Audio's achievements are reflected by our worldwide reputation for unsurpassed musical performance, reliability, consistency, and overall value. Classé's philosophy is one of technological evolution, not revolution. Building on what we know works. The new Classé CA-401 was developed using the knowledge gained during the ressearch for the spectacular OMEGA Series amplifiers.

We knew we were embarking on a great adventure when we started the cost-no-barrier design exercise which culminated in the development of the OMEGA Series of amplifiers and preamplifiers. Through the exercise we discovered the revolutionary OMEGA circuit designs, with the result that each product in the OMEGA Series has no sonic equal.

The new CA-401 benefits greatly from a trickle-down of technology from the OMEGA Series, and represents on its own a long step forward in amplifier design. Each channel of the amplifier is balanced from input to output, much like an OMEGA, and the amplifier has an oversized, superbly regulated power supply, again much like a OMEGA

The CA-401 is balanced from input to output, resulting in a greatly enhanced signal to noise ratio, lower induced common-mode distortion, lower distortion overall, and freedom from grounding problems. The power supply of a CA-401 includes a massive, shielded toroidal transformer. For each channel we use a large collection of small power supply capacitors. Small capacitors "drain" and "refill" extremely rapidly and completely, supplying all the power required when the source demands it, with no bounce or overshoot. The fast, clean power supply allows us a higher degree of accurate voltage regulation at all stages of amplification. Thus no matter what program material is being played, at no matter what level, the voltages at all amplification stages remain completely stabile.

The oversized, fast, very high current power supply allows the amplifier to deliver the full current and voltage required to even the most difficult speaker load. The CA-401 delivers sound which is clean, liquid and effortless. Imaging, with the better recordings we all enjoy listening to, is both wide and deep. In fact, imaging seems real and human, without the artificial hard edges so common in lesser amplification.

The Classé CA-401 will open your ears again. It will give those favorite recordings, the ones you've gotten used to, that same ability to surprise and delight they had when you first heard them. Just sit down and listen, you will be delighted.
