I am selling off my Parasound amplifiers from my home theater (others are listed on as wel) . These amps have been workhorses! This amplifier is super quiet and very powerful. The do run warm but dont seem to care. All 3 of the amps on here have volume pots on them for channel volume. Interestingly, the only issue I have had is that the pots have become noisy over the years. If I was keeping these I would bypass the pots (simple soldering job) as I have never needed to turn them down from their THX setting which if full volume.If you are interested in these amps and want me to do this for you, I would be happy to assuming they sell for a few bucks so its worth my time to do this. I have this amp and 2 of the HCA2003s listed as well.I have 2 surround processors available on as well.Info from Parasound below.
HCA-1200II is designed by John Curl, one of the world\'s most renowned circuit designers.
It is among the elite of the finest power amplifiers ever made. You have made an outstanding investment in your musical and home theater pleasure for years to come.
Every part, every direct-coupled circuit, has been painstakingly selected for optimum musical quality on the finest and most challenging music and loudspeaker loads. Take a look at the special features found near the end of this manual to fully appreciate its considerable prowess.
