I sold my Odyssey Stratos amp and bought criverjr's ATI 1502 amp to power my front speakers (Rega Naos). I also bought another ATI for my rear speakers. I didn't have any reason to change out amps -- I just wanted to try something different. Anyway, as most of you know, the Odyssey is a very highly regarded amp. Both the Odyssey and the ATI are rated at 150 wpc. The Odyssey is HUGE, whereas the ATI has a "small" rectangular shape (a bit taller with half the depth). I prefer the smaller amp because it conserves cabinet space. I've got both ATI amps resting where the big-ass Odyssey used to reside. The ATI amp can also be bridged for 450 wpc.
OK, so I hooked up the ATI and popped in my demo DVD. At first, I wasn't overly impressed with ATI's dynamic ability relative to the Odyssey. I felt the ATI could do better, so I changed out the speaker connections. The ATI doesn't accept spades, so I only had one-half of the spade tightened into each connector. I found a couple of pair of banana plugs and attached the spades to the bananas. Then I popped in the demo DVD again and BAM!!!! Oh, how sweet it is. Both the Odyssey and ATI appear to be equally powerful, but the ATI is so much more realistic than the Odyssey. While the Odyssey seemed to over emphasize certain sounds, the ATI delivers sound in such a well-rounded, life-like manner. Great detail, man, and it ain't even broken in yet.
I'd love to try this amp on music with a 2-channel system someday. I'll bet if you paired this puppy with a tube pre, you'd be in sonic heaven. So, once again, I have "upgraded" my system by purchasing a less expensive amp. I certainly did not expect the ATI to best the Odyssey, which is an awesome amp as well. I'll say it again -- price don't mean a damn thing in the hifi audio world. Because of this, I highly recommend the ATI 1502 amp. For $350 - $400 on the used market, it's hard to beat. IMO, it'll probably destroy the usual suspects at this price point -- Parasound, Rotel, Outlaw -- I've had them all and I'd choose the ATI without hesitation.
