Revel Studios- amplfier suggestions please


Hello everyone
interested in people's experience with amplifiers for these awesome speakers.
i am driving them currently with a cal audio mca 2500 (500 wpc)
wondering if any "audiophile amps" either monoblock or stereo would give me a significant improvement?
also how do you all like these speakers?

Tubes are good, but I ended up with an interesting alternative harmonic precision. These are 110 wpc mono amps that are over 97% efficient. Incredible sound with my Revels. Very tubelike, but with advantages of solid state. Check out audiopoints.com. The levinson 400 series amps are great as well as conrad johnson.
I still like the SF Power3 amps with them although the Classe monoblocs come close.
i agree the sf power series
the power 3 are hard to get on audiogon though
i have seen a power 2 but just feel that it alone may not have enough power for these little monsters
any thoughts on older krell mono's or high power amps?
also, how many of you out there are bi-wiring?
I am bi-wiring with MIT CVT 770 speaker cable. It is very neutral, and it really lets the bass come through, something my old Tara cables did not do.
I biwire my Studios with Audioquest Dragon cables and power amps are Krell FPB 250M monoblocks. Interconnects are AQ Amazon. So far I am happy with my setup.
