Darren Myers, Parasound’s new Vice President of Research and Development, explained that “the goal of this design was to create an amplifier capable of 100W of class-A operation into 8 ohms. To accomplish this, the voltage rails on the output stage were lowered, reducing the maximum voltage swing into 8 ohms compared to a stock JC 1+. This allows for a manageable amount of power dissipation on the output stage while having adequate quiescent current to achieve the 100W class-A power specification.

“To optimize this class-A operation, there are several internal modifications applied to the circuit, including transformer and component value changes. John Curl worked directly with the Parasound design team for over a year to design and optimize the modification process. John and the entire team at Parasound are so proud of what we’ve come up with. The outcome is truly something very special.”
