Parasound JCM250 Monoblock Power Amplifier (each)

A 250 W, ultra-high-bias class A and AB amp designed by John Curl.

With circuitry designed by the legendary John Curl, the flagship Parasound Halo JCM250 is a world-class power amp. It offers 5 W of class-A power before switching into class AB operation. A new John Curl driver stage employs a cascode circuit for greater open-loop bandwidth and superior linearity.

Parasound's Bybee Music Rails offer active high-frequency filtration for the input stage. Gain can be set to 29 dB or 23 dB gain for optimum compatibility with high-gain preamps or extremely efficient speakers.

A separate R-core transformer for the input stage suppresses noise on the power line. The direct coupled signal path means no capacitors or inductors get in the way of great sound. The JFET input stage is connected to a MOSFET driver stage. The 42 lb. amp uses a heavy shielded toroidal transformer. Full power is rated all the way down to 2 Hz for unrestricted low-end bass
