This is a very competent amplifier! These monoblocks sounds like $10000 amps.
I have sold my Krell FPB 300cx because these amps sounded more musical and warm than the Krell. A impressive soundstage and very relaxed sound.
I was very positively surpised when I got them home and had them burned in over a couple of weeks
