So I just picked up an adcom gfa 535. So I picked it up off craigslist for $60 from a guy that had probably at least $200,000 worth of gear spread out through 3 different rooms. Any way this thing is in absolutely mint condition, I mean it is nice!!!! He was selling it for a friend that used it in an office for multi room speakers. Got home and hooked it up and all I can say is WOW!!! 2ch music has never sounded so good in my house. I just can't believe the impact this has made, the sound is better in every way. The highs are soooo much clearer and waaaay cleaner, the mid bass is way tighter punchier and deeper, the sound is just way more accurate. I plan on picking up two more of these for my center and surrounds. Here is a good review on it. LINK
