Parasound HCA-1000A Modifications


I recently completed some modifications to my Parasound HCA-1000A a few weeks ago, and HOLY COW!!! Now my $300 amplifier sounds like I spent easily 10 times that amount. It's amazing what can be done with a stock amplifier--especially one as good as the HCA-1000A.

Anyway, my question is this: I am thinking about writing a manual about modifying the HCA-1000A and offering it for a small fee--maybe even putting together a "kit" containing the manual and all necessary parts. Would anybody out there be interested in such a manual or kit, or should I not waste my time?

the Parasound HCA series is still a very good amp in 2017.
Happy Listening!

A older thread yes but these older parasound amps are special and I'm certain with mods there even better. I also have the HCA-1000a and a HCA-800 that I upgraded my self with all new Nichicon caps. Wasn't expensive at all and made an Audible improvement plus extended the life of the amp. Still have both amps and I am enjoying them. It is important that you keep the replacement caps at the same values except you can use a cap that is rated at a higher voltage but the capacitance should be as close to the same. Only use exact replacement caps and pay attention to whether they are non polarized caps or polarized caps.

Avilex ! Did you ever end up making these guides/kits? I would be interested in 1. Or  if you or anyone in the group can send me some info, that would be lovely. I know this is a super old thread but figured I'd give it a shot. I think a series of these guides/kits for different "mid fi" amps would be a great idea. My nad 2200 comes to mind as well! 

@south43 , was not an amp I did. I did not use solen caps. Have to be careful with the solens, they can end up sounding lean and thin in the midrange. 

I was looking at one of these with modifications in mind - Did you mod and test as you went? I would be willing to bet a capacitor refresh and wire made the biggest difference. $100 all in on parts, I was considering $100 on new cable alone - signal and speaker. It's a shame on this model that signal runs to pots and back.
