Newbie -- expert thoughts on PA2400 vs GFA5400?

Saru,

I've tried the low power & high power route.
If your system is in a small room & doesn't ever clip,
you're fine.
If your in a larger room, and you want to play loud,
you'll want more power.

I'm currently using a PA2200 which surprises me considering some of the amps I've had in my system. I purchased it on ebay, one of those accidental buys. After it arrived I rewired the AC input and installed IEC socket. Then I rewired the output and installed some Cardas binding posts. Great little amp for what I paid.
A few years ago I owned both the HK PA2100 and the Adcom 535II at the same time. The HK was the better amp IMO. Quieter, smoother, and just more fun to listen to. As I am one of those who always removes the cover to see what's going on inside, I'd say the Adcom looked like the better amp. Seemed to have much more going on in there. Then again, there is something to be said for simplicity.
Also owned the Adcom 5400 a while back, but don't remember it much.
I agree with Danielk141 in that more power isn't needed if conditions don't require. My room is small and I rarely listen at high volume so 100 watts per side is plenty. Good luck.

Hi folks,

Thanks for the great advice. This helps a lot and is probably saving me much needed funds. Thanks for helping me not waste funds for what likely would have been a lateral purchase at best.

It's small room so perhaps what I have now is sufficient.

I meant to make a simple suggestion if you want to compare the sound between HK and Adcom. Pick up a PA2200 on ebay, I got mine for $105, and listen. It's an inexpensive experiment.

If you can snag an H/K Signature 2.1 for $500, do it! It is a very high-current design and sounds marvelous. You could easily use that amp for a year and then sell it for what you paid...

Happy New Year!!
