Sfar is correct in that the 520's need some warmth upstream. With solid state gear, I would recommend heavy copper cabling throughout. If a subwoofer is going to be used, it would greatly balance out the range so the upper end will not come across so hard.
Regardless, the Usher 520 is one of the best mini-monitors I have ever heard. The midrange will make you melt in your listening chair.
