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.

If you have questions about how an SET or other 'current source' amplifier will drive a speaker, maybe this link will help in understanding what is going on:

Thanks for the read Ralph! It would seem that the distortion spectrum or bandwidth is more important with respect to the preceived loudness then the intrinsic acoustic power? EG: to make a rig sound less forward one would strive to minimise odd distortions in the presents range ( 1500 Hz).

The Almarro 318B can drive some difficult speakers.I use one to drive Gale 401a speakers and most 100 watt SS amps struggle with these speakers.A 3.5ohm load and 88db sensitivity.

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.
