I am using the Panasonic SA-XR 700 in all digital to drive my Emerald Physics CS2's. I believe they are an excellent value. Will be really hard for you to beat them for at least 2-3 times the price. Now, I have not compared the Panasonic to other set-ups specifically with my speakers. I have heard high end amplification from Classe', Burmeister, McIntosh etc through completely different speakers so this is not really a far comparison. All I am really saying is that the digital section of the Panasonics are awesome.
