I'm looking at getting 2-3 Adcom GFA555s used.

What other power amps should I be looking at? Haflers?
 
I currently have a 545 II. I think I could use more power for some of the more intense scenes.
HT.
 
the 555 is a really good amp if you need the power. really good.

i might say look into Rotel, maybe a 991, ive always like their sound and super clean, but they can be tricky on price. sometimes you can get really good deals on their 90s stuff, sometimes its expensive.

Well the two brands for amps I'd most recommend are Emotiva and ATI.

Emoitva makes very good, quite cheap, amps. You want lots of power for not lots of money, they got your number. They aren't the kind of people who hind behind BS either, they publish their Audio Precision test graphs of their amps.

If you want something higher end, ATI is a good choice. Make sure to search for "ATI Amplifier" as to not get nothing but the GPUs. They make big, fairly expensive, heavy hitting, extremely well designed amps. They actually build amps for a number of brands, but the ones they sell under their own name are exceedingly high quality. Nothing fancy to look at, these are the kind of things you install when sound matters not style.

If you want dedicated amps, those would be the two I would look at first.
 
I like Sycraft's advice. Note that Emotiva's 5-year warranty transfers to later owners. ATI offers a 7-year warranty, though I'm unsure if it transfers. However, you do get it on B-stock from their factory outlet.

Might also look at Parasound when buying used. There's a lot of it on Ebay, and some of the prices are REALLY reasonable.
