I have a cyrus system including cyrus 7Q cd player with psx power supply,cyrus ca7.5 pre amp set of pa7.5 monoblocks with spender s8 speakers. Iam considering adding two further monoblocks which would give me a total of 4 monoblocks so my speakers will be bi-amped will this be the best way forward or should i look at my source cd setup? Or should i consider a change of speakers. Or do all three to get the best performance. Any readers got any suggestions re the way forward with my setup.

Yours Mike Byrne.
