Mancub1,
I vote for Emotiva xpa 1 monos!I use a pair daily on a pair of Thiel 3.7’s,which can dip to 2 ohms!Amps don’t even get warm,sound good and are affordable.Sure you can spend more for marginal gains but I believe it’s not worth it !If they break,that’s another story.Someone once posted that I shouldn’t have such expensive speakers on Emo amps!Im getting great sound and I’m happy!I have heard more of a difference changing preamps than amps.Working on the source helped more that anything so far.Emotiva amps are always easy to sell if you don’t like them!I say get the best speakers you can.
