Hi. I am running a cd62t cdp and a pair of wharfedale diamond 9.1 speakers and I am looking for an amp to compliment these. I have auditioned an alpha 5 from my father in law and whilst that dos offer some magnificent staging and mid-presence, I do feel that in the mid-bass area I am losing presence (even sections of bass arguably). I am looking to buy second hand so was wondering if an Alpha 8, an Alpha 9 or a Diva A65 would be my best bet? Any other ideas welcomed. Thanks. Phil.
