What ICs, power cords and speaker wire are you using? These may make a bigger change in your system than the amp or preamp depending on what you are usig now. I compared 12 amps over the past four months and there wasn't that big of an improvement over better cables.
should I upgrade my amp
My system contains Spica TC-50 speakers, Velodyne F series servo subwoofer, sony scd ce775 player, Adcom gfp 710 preamp and Adcom 545 mkII amp. Should I upgrade by replacing the amp with the Musical Fidelity Acr3 amp which can be bought for around a grand? Should I not even consider this unless I also change my pre-amp?
Thanks in advance for the advice
