B&W 801 separate amplifier just for bass drivers

so, why not consider other amps. Does it have to be Levinson? what about Audio Research 300.2, BAT VK600, McCormack DNA-500, Krell FPB?
can't you seel the ML and get a used Krell FPB600 on Audiogon, for example?
I think you may encounter a problem with the 2 different amps like that driving these speakers. You may get a timing issue where the bass will not be always on time with the rest of the spectrum. I don't think you'd like that. My advise is to go with a single amp or a monoblock configuration. This is more rational than using Rotel along with Levinson. What I would do, if I wanted to drive the 801s properly, I'd get one strong amp or a pair of monoblock amps. The 801s can not be underpowered and this is important.

You can use two different amps -- as long as their input sensitivity is the same. I can't recommend specific products as I don't know the cut-off frequency of the mid-highs.
Of course, we assume your preamp has no trouble driving two parallel loads?

Thank you Adp1

You're right. I strongly evaluate other brands. But I still have a prejudice concerning Krell caused by older designs that sounded harsh/bright/brute.

Have they musically improved a lot in the last 10-15 years?

AK, I've heard FPB series amps some time ago and didn't find them harsh. It depends on other equipment as well. McIntosh and Classe amps sound quiet nice with B&Ws as well.

Thanks Audp1

Which of the Amps you name should I try first? What are your favourite products?
