If you spend that kind of money on those speakers and the Slimdevices is your primary source you are doing them disservice.
speakers similar to Magico Mini's
What other speakers are available that are sealed box with first order crossovers and high quality drivers? Either stand mount like the Magico or a floor stander but with a price tag a good deal south of the 22K. I have not heard the Magico's but I always seem to prefer the sound of sealed speakers. I have original B&W CM1's which are infinite baffle but not first order crossovers which sound very good and Triad 3's which have first order crossovers and are in my second system and I always am taken with the sound.
