I doubt you would hear any differences between the two. I for one, have never been able to tell different amps apart from each other. Just make sure that what ever you go with, has enough current and can handle low ohm loads. If I were you and in the market for a new amp, I would go with a used Rotel or a used Parasound as both of those have high current, can handle low ohm loads, and are generally built like tanks. I see no reason to pay $2,500.00 for a new amp. Although I can't tell differences between good amps, I can, however, tell the differences between preamps and source components. Upgrade your source or preamp, or even your speakers. That will net the biggest gain in sound quality.
