Parasound JC 1+ Monoblock power amplifier

Parasound JC 1+ Monoblock power amplifier Parasound's monolithic 83-pound JC 1+ can kick out the jams with absolute authority. It delivers a whopping 450 watts into a single channel at 8 ohms, and it's stable down to 2 ohms, offering flexibility to drive even the most demanding speakers. Class A/AB operation for smoother sound The JC 1+ uses Class A/AB amplifier technology, which we don't see every day. So let's talk about what that means. Engineers and audiophiles generally agree that Class A designs offer the purest sound, but they tend to run hot and take up a lot of space. As a result, home audio amplifiers often use a compromise known as Class AB, which hands off part of the audio signal to a different set of output transistors at high power levels. AB can sacrifice a bit of signal purity, but it lets the amp run cooler and more efficiently.  So this Class A/AB amp operates in pure Class A mode up to a higher power level than most other amplifiers in its price category, befo
