I'd go for the new Spectral DMC30SL + DMA 150 Series II.
Awesome combination with the Amati's. It's what I'm listening to right now -- fluid and quick, with soul.
MIT Oracle V2 speaker cables mate perfectly with this trio.
If you live in the Bay Area, go hear this combo at Music Lover's Audio in Berkeley. Ask for Jae or Hugh.
