I would second the recommendation on the Belles Aria which I now own. I tried the Ayre AX-7E and the Hegel H160 in my system driving my Harbeth SHL5+ speakers and the Belles bested them both in my opinion.The Belles is rated at 75 watts per channel and may not have enough power for you but it drives my Harbeth's very well. I have heard it with the Ryan R610's, the Vandersteen Treo CT's and the Magnepan .7's and it drove them all very well.
