I'm using a PS Audio Trio C-100 ICEpower integrated amp with my LSi9's in the living room. My previous setup was a Transcendent Grounded Grid tube preamp with a gainclone amp. That setup sounds better to me at lower volume than the C-100. I live in an apartment so this is important. At those times when I can increase the sound level, the C-100 sounds nice and the remote control is convenient.
