Class D and Avalons.
I apologize, this may seem like a boring rehash of-you've heard it all before but...
I didn't expect that I'd be using another class D amplifier to power my Avalon Eidolons but I simply couldn't help myself. The PS Audio HCA-2 with Black Gates served me well until I could acquire my dream, linear solid state amplifier. I admit to being so intrigued by more reviews of a single product than I could recall that I decided to take a flyer on the reasonably retail priced mono blocks. As luck would have it, a pair popped up here for a reasonable savings below retail.
Not having anywhere near the experience Robert Levi has had with different amplifiers I can't attest to all his claims. I can say that these mono blocks sound better, way better than any of the other amplifiers I've had in my system. While our choice of media and our systems differ in many areas the relationship between the Avalons and the NuForce 9se's is as he describes. http://www.positive-feedback.com/Issue26/nuforce9se.htm
Will there ever be a best amp for your Avalons? In any case, if your wallet is hurting from your indirect contribution to the Colorado State Tax Board, you could afford to spend a few dollars more in smelly Milpitas, California to power those wonderful speakers with impressive results.
