Thinking of getting a Krell FBP 600

Thinking of getting Krell FBP 600 to run my b&W Nautilus 801's through B&K reference 30. Any issues I should know about with this amp. Can you leave it on all the time? Have a 20 amp dedicated power line. Is that enough for the amp? Anyone have issue with breakage as I'm not eager to move a 185 lb amp and ship it. In fact I can't imagine that!!!!

Any input is welcome -

Thanks,
