Description :
The Coda S5.5 power amplifier is designed in an effort to provide the listener with unmatched sound quality, design, and construction. The S5.5 is very similar to the famous well reviewed S5 with significant improvements to the thermal tracking which allows the amplifier to become even more efficient and an increase in reliability. The circuit topology is still identical to that of the Coda S5. The engineers of Coda Technologies say that the Coda S5.5  was essentially everything they could think of wanting in an amplifier. Like the Coda S100, the S5.5 is DC-coupled, using a FET input, MOSFET voltage-gain stage, high-speed bipolar current-gain stages, no repeat and no overall feedback. FETs are inherently better at voltage gain and their transfer function is better.

The Coda S5.5 also sports what Coda has dubbed Precision Bias topology. It provides a more efficient and elegant implementation of class-A amplification by fine-tuning and precisely calibrating circuit parameter control to yield an exceptionally smooth cooperation between the positive and negative output banks. The front end of the Coda S5.5 is designed to operate without ever entering Class B operation as is common in many other designs. This combined with excellent high frequency design insures linear operation at high speed, and translates into a sonic reproduction which is extremely transparent in character. The sound is remarkably clear and detailed. Very few amplifiers convey the snap and forward momentum of music the way the Coda Technologies S5.5 does. Listening to music through the S5.5 is a delight and a sensation. If your response to music, or life, is to dance, swing, and sway, then the S5.5 just might be the power amplifier you've been looking for.
