I've recently bought a ca640a amp to pair with my 640c and ae evo 1 floorstanders. It's a great combination with some cds but with others it's far too bright at the top end, painfully so on some tracks. I've tried turning the treble down, moving the speakers round and even bi-wired them, but no difference. So, today as an experiment I wired the hf left & right to a pair of celestion f1's I have and the lf l&r to the evo's. In other words the bass comes out the evos and the treble out the celestions. There's no denying that there's a trade-off in sound quality at the top end, but the brightness is gone and I can play just about everything I've tried at a high-ish volume,between 10 and 12 on the dial.
My question is - am I damaging the amp as it is effectively only driving one pair of speakers? It certainly doesn't feel any hotter after a couple of hours continious play at reasonably high volumes.
