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

I used to have a pair of the Spicas with matching Hercules stands...and an older Class A MF intergrated...and this was the best combination I came up with...huge soundstage,and ofcourse...legendary 3-d imaging which the Spicas are famous for...dont know if this helps...a tube pre would be a nice addition as well...
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.
I agree and second bob bundus's comment concerning the pre-amp it is the most important component in your system.

I don't know for sure whether I would go preamp or amp. If I were to change the amp I would consider going with a Forte 4a and maybe even two of them.
I use a Jolida 1000a integrated tube amp with Spica TC 50’s. Give tubes some thought, I find tubes takes some of the glare out of the Spicas.
