I'm thinking of upgrading my hi-fi amplification, current set up is rega p3, arcam alpha8 integrated + alpha 8p power (bi-amped) monitor audio 5i, alpha 7 cd, Van Den Hull speaker cable. I would still like to keep it bi-amp, if it was worth it. However, a friend has recommended Music Fidelity A5 and not bothering bi-amping for now. i listen to my turntable more than my cd player and enjoy detail in my sound. Any suggestions?
