collection. I had the SA250 Mk2 in my system and it was truly a great class A and A/B piece that can be toggled when you want to go from 1 to the other. The SA250 MK2 was very musical and holographic with great bass but suffered a tad in detail in the upper mids and highs. Of course that was maybe due to having it connected to my Sonus Faber Olympica Lilly's at the time more known for there silk dome tweeter or me maybe not playing enough with cables etc.
My setup today his will include Focal Sopra #2's with a titanium tweeter and bigger more detailed midrange.
Please keep me posted if you have any comments regarding this amp as I don't have a near by dealer where I can audition one.
Cheers
