Power amp for Audio Research SP16L pre-amp

Well I will be using it with some Proac Reference 8 signatures.
The sound I'm after would probably be a neutral sound.

I would also consider the ARC 150.2 or the 100.2. Both have more than enough power for your application. I'm using a 150.2 with my SP16 currently and am very pleased. It runs cool, is so reliable and sounds great. I had a 100.2 which had a bit more texture and body in the midrange and slightly more natural highs. It is widely regarded as one of the best ss amps ARC ever built. It will cost you though--they come on the A'gon infrequently and sell quickly at asking price. For $500 less you can get a 150.2 that will last forever and sounds nearly as good.

Dodgealum, I just found your post and am curious -why did you replace your 100.2? I've been looking for an amp to go with my AR LS 16MkII and was told the 100.2 is more musical than the 150.2. Would appreciate input from other Agon folks who are familiar with both amps.

Oops, I apologize! I'm relatively new to Agon and forgot that I should not be directing attention away from the issue that started this thread, but should instead start a new one to get responses to my question.

Stutz:

Your "diversion" is less so than most and therefore I think warrants a reply. Basically, I sold my 100.2 because my equipment is stored in a cabinet with little room for ventilation. You can see my setup by clicking on "system". The 150.2 is a digital switching amp and therefore develops very little heat (and also uses very little energy--call it "green" hifi. I really feel you give up very little sonically between the two amps. Is the 100.2 better? Yes. Is the 150.2 very close? Yep. If you have the room to breath and can afford the 100.2 that would be my recommendation. Otherwise, the 150.2 will match up very well with your preamp. Hope this helps.
