I'm pretty happy with mine. Here's a video of my Vienna's hooked up to my Bel Canto C5i.

The amp in the C5i, while rated at 65 watts x 2 into 8 Ohms in reality has 30 amps peak current output! (The previous unit while having more watts only had a 12 amp peak current capability.) Plus, the C5is amp is stable to 3 Ohms! Good Stuff!
