hey man have you ever used any Adcom amps in the past? My buddy just came accross an old amp it is model # 4404, I read a few reviews on it including the review on ecoustics about it and they are all amazing. it does 600x2 @ 2ohms and is described as being sonically superior to all amps of its time so let me know if you have heard anything about them at all.
I haven't had a chance to test that amp, but it does sound like one of those quality "old school" amps. The model 4404 is a 4 channel amp. So it won't be that useful in sub application. It has good damping factor (600), SN ratio (100db), and wide bandwidth. The only thing I couldn't find was the slew rate. I'd recommend the amp for anyone needing 4 channel amps for components. I am not 100% sure if it's 2ohms stable bridged. At 4ohms it's 150w rms x 2 bridged.
well the reaon I thought it would be worth trying in a sub application is because of this statment.
"Its impedance handling capability is very low, and allows the user to patch it into a multitude of subwoofers or mids and highs." He said I can have it so I am gonna check it out. I will let you know how it sounds, compared to art series, and Orion HCCA g4.
