At first I was a bit skeptical of the wattage rating, yet it can drive most anything I've tried...makes the big DeVore X's and Vandersteen Treos sing. And stellar with the DeVore Orangutan series, and even my beloved lil Falcons.
Like the turntables/cartridges the Haven is now demoing, the integrateds now here are all at the top of the heap, and the Riviera is certainly a contender. Schedule an appointment for a listen. But be warned, this AIC-10 is addictive.
