Well thats a good question, I only have Pioneer receivers and amps and an old Sanyo to compare it to, But i would say thats its a little softer than the Pioneer if thats any help. I am using a set of Paradigm Mini 3se that i have used on the Pioneers before so i get an idea using the same speakers. I see that the fellow has tested the amp to 450 at 8 ohms from your post, but i have to tell you that i think its allot lower than that. I have a Pioneer SA9100 that puts out 65 rms and it packs a mean wallop that this amp cant compare to in the lower bass levels. But just the fact that these amps seem to be mysterious it may be worth your time to get one. The nude pics are the same as my amp, it has to be the same one. Like i said i only paid $100.00 for it so dont give him $300.00 if you can get away with it. But i really need to hook it up to my Sound Dynamics SMT1000s and give it a good run to see exactly what it will do. Maybe i just need to open it up to see that much power. Let me know if you get it or not.
Did he give you any other information about it?
