I've had great luck with a BelCanto SET40 (stereo amp using single ended 845's) driving my Dunlavy SCIV's which are 91dB and a stable 4-5ohm load. Dynamic, extended at the frequency extremes, huge soundstage, great body/harmonics/detail and provides the single ended "majic" people crave. A great option for speakers that are not friendly to the 45/2A3/50/300B amps.
SET Amp question
I'm interested if anybody has experience using a SET amp with certain harder to drive speakers, like the Dynaudios and OHMs in my system, or others. What might one expect from such a combo sound wise? Could it work well say in a smaller bedroom system that will not be played too loudly in general.
