Which Op-Amp???
Has anyone compared the various Op-Amps? I must confess I'm using 1875 in Non-inverting mode, never tried anything else yet but my Brother requires higher power into 4 Ohms, any suggestions? 3886 seems favourite but I am interested in the music first.

My amps are using pretty standard (Rubycon ZL) components but I now have some Elna Silmics as well as BG standard and N (Super E configuration). I cant wait, my current clones are pretty damned good outclassing some very esoteric commercial equipment that I own.

I prefer OPA 549 to 3875 and it is rated at 8A so a good choice for 4 ohms. One of our gurus ,Peter Daniel, said that he preferred 3875 over OPA549 but the difference was not great.I don't think anybody has expressed an opinion on 3875 vs 3886.
