So i'm doing my daily craigslist browsing and I came across an Elan z-660 6-channel home theater amp, which can be be bridged to 120watts rms @ 8ohms. Originally I was considering purchasing this to run my fronts but what little info I could find says the sound quality sucks and it wouldn't be an improvement from my Rxv-1800. However after e-mailing the guy I got him down to $75 and it's still in the original box and plastic wrap. The "retail" price is $820 and I found a few used in the 250-300 range. So should I just scoop this and ask questions later, try to use it, or buy it and try to throw it on fleabay? Any advice or opinions on these amps would be appreciated. Thanks.
