i have a chance to hear them recently. i had 2 on hand, but the power switch on one was broken.
sonically speaking, it is very warm in the midrange and a little soft in the bass. a little distant in the soundstage department. the detail was a little lacking. not a bad amp, but nothing special imo.
please keep in mind it is a 50 wpc class a amp and i was using it alon II which are 87 db efficent. when briged, they are 200 watts rms.
i think you can do better.
alot depends how much you want to spend, what speaker are you u using it with, power requirements, system matching etc...
hope that helps !!
