KRELL FPB 650M MONO BLOCKS ..?

Hi..
I'm currently using a pair of krell fpb 350m (mono blocks) to run my B&W 801N. I would like more power for my pair of B&W 801N. And I have located a pair of krell fpb 650m (mono blocks) near by and is available for me to purchase. I would like to know will that be a great upgrade for my pair of B&W 801N. Any advice and opinion will help.

Thanks

"I would like more power"

I don't think you would gain anything at all, can't believe you don't have enough power already.

What are you trying to get that you can't get with what you've got already, better bass, sweeter mids and highs, change in tonal balance?? list your source and preamp as well.

Cheers George

I have no experience with Krell and cannot comment on your specific question, but when I bought my 801Ns I had an MC7300 that at 300W/channel I thought would be fine. It wasn't. Replacing the MC7300 with a pair of MC1000 monoblocks made a big difference never regretted.

As tested by Stereophile your 350M's can give.

"maximum power delivery of a monstrous 475W into 8 ohms (26.8dBW), way above the specified power. 850W was available into 4 ohms (26.3dBW) and while I measured 1060W into 2 ohms (24.2 dBW)"

I cant see any improvement happening by going to the same topology even more powerfull 650M's driving your 90db speakers, as both amps would drive the 801n speakers on their ear.

This is why I ask what are you trying to get that needs to be different, and what is your source and preamp?

Cheers George
