Audio research 100.2 any good ?????

WOW! ARC will no longer repair them!

I would pass on this one!

Does ARC still repair the D240, D400, D300????

They were good in their time.

I would contact arc to confirm, they are very responsive in my experience 

The early transistor ARC amps were dogs.....I wouldn't touch it.  Grainy, no depth, no air, no good.  The one you're speaking of may be different, but the one I know was not a good amp.

ARC SS amps from early 80's were dogs, but not the SS ones from the 90's.

I never cared ARC SS digital switching (DS) amps though.

+1 @stringreen .....I agree.  I owned the ARC 100.2 and although it was quite good in the day, I think it resting on its laurels now and has a nostalgia attached to it.  There are better amps out there now IMHO.   Ayre, Belles, Blue Circle to name a few.  That being said, I've always liked their preamps and tube integrateds.  Regards.....
