Here is some discussion of my experiences with digital amps, along with other bi/tri-amping topics: Clarity and accuracy in tri-amping monitors?
There are links to outside reviews of older Bel Canto models in that thread as well, if you are interested. And of course plenty on the web for the newer models. Generally quite favorable.
In short, the Bel Canto eVo 200.2 digital amplifier is the finest sounding (or rather, lack of sound
ing) amplifier I've used. I've tried with Paradigm Reference 3-way floor standing speakers (similar to several B&W models in my experience), SLS ribbons, and PMC TB2+ and had positive results with all of them.
When using the Bel Canto with PMC TB2, the treble, midrange, and bass are more perfectly balanced than with any other amp/speaker system I have ever experienced.
Certainly no "veil" here -- exactly the opposite. The resolution of detail is almost holographic in this combination.
After a lot of experimentation over the years, I now have no desire to even consider any other amplifier or speaker.
