I have B&W N801s and am currently driving them with Krell FPB600 amp, and they sound terrific together. Amp has no problem in handling N801s whatsoever. Also, FPB600 has a standby mode, so you don't need to leave it on like the older models. Another feature I like about the FPB600 is that you can change power cords.....
One caution though, I would suggest that you buy a dedicated 2-channel preamp if you want to hear what FPB600 can do. I used to use Lexicon MC-1 processor as my preamp, and didn't know what a horrible 2-channel preamp it was until I changed to Krell KRC-3 and realized what I was missing A LOT all along.... I had read a lot on Audiogon and heard from many audiophile friends that a digital processor just can't deliver 2-channel audio, and I didn't believe it. So, it seems your B&K Ref 30 is also a digital processor by design.
Regarding shipping, I found my amp from a seller in my neighborhood, so I went over an personally hauled it over. But if you have the original FPB600 packing, I can't imagine that one can't ship the amp. You might want to check with Krell on how they handle amp shipments and whom do they use, since they probably get a lot of amps back for checkups and updating. Krell service is absolutely SUPERB!!!
Hope this helps!
