I have a 7 channel system with d-sonic's ICE amps powering an MK150 system and they're excellent. Everyone that watches on this system, which has an 11' wide screen loves the sound, especially my girlfriend. I have been thinking of selling my Adcom GFA7707 for another ICE Amp. Right now I don't have an absolute need, but if I were to buy a 9.2 preamplifier, then that might be the time. I highly recommend listening to an ICE with your favorite speakers if you get a chance.
