MC402 vs FPB 300cx

I would choose the Krell.

I heard the MC402 with B&W 803S and it was pretty good, but nothing I would buy though.

If you want speed, detail and bass slam, then go for Krell.

Since you're using tubed pre, I think you will be good with the Krell FPB amp and B&Ws.

Thanks Audphile1....Thats what I think too. It's funny, I read around the forums here and elsewhere, and I can't believe how many Krell haters there are out there. The stuff sounds awesome, and one of the few I have listened to or owned that balances the full spectrum properly. Alot, and I mean alot, of very good products out there roll off on the bass. I am not a bass head, but it makes no sense to me to own something not capable of producing a tight punchy bass note. Bass is obviously interpreted differently among manufacturers I guess.

Would love to hear from more people with experience with this amp. thx!

Since you seem very concerned with bass, you should stick with the Krell. However, if you really want awesome bass, the 804s are not a very good choice to begin with. I have a pair right now and they can't hold a candle to my 926s in bass performance. You would get a bigger bass improvement by changing speakers than by changing amps IMO. Not to mention it could cost you a lot less money too.

The 402 does have rounded bass which I interpret as a 3D sound rather than 2D slam but everyone sees it a bit differently. From what you've said, I think you will be happier with another Krell.

It sounds like bass is your main priority. In that case, stick with Krell.

I also agree with Arthur about speakers. N804 by nature don't go low in the bass. Krell will definitely help to bring out some bass impact, but ultimately, if you like B&Ws, you should go hear the 803D. IMO these speakers are a big improvement over the previos series. They have detail, are smooth sounding and with bass performance that is on par with the 802s. But since you are going with Krell, it'll drive most any speaker you will get in the future.
