Is this amp sufficient to drive my 803D

Bob, thanks for the response,

Currently I have the amp and blue jeans cables biamped to the speakers bare and banana plugs

Yes I love to listen to music very loud
but, most of the time due to constraints
low,
most of the time im 14 feet away

Would a bigger amp open up the speakers at lower listening volumes?

Thanks

Bob sorry should of clarified this better

currently I have the Krell 400xi hooked up to the B&w 803D biamped 20 inches from the rear wall

I'm using a Yamaha receiver for the fm tuner purposes only!

Im just curious to hear if there are better alternatives for amps given the size of the room im in for listening

I will definitely check out those ATI amps! lots of power!

Yes correct Bob, Bi wired, not Biamped

Would biamping be better, I have a Sony Tan 9000es power amp lying around, would this be usable?

An AVA FetValve Ultra 550 would work well for you. Over 250wpc and stable to 2 ohms. And sounds fab with B&W with stock tubes (though cannot recall if I heard it driving 803 or 804). (Disclaimer - I have one for sale.)

you're fine...no need to bi wire either

Jaybo,

I have noticed a big difference when bi wiring to the speakers, bigger base, and stage,
even improvement when using banana plugs, instead of bare wire these speakers are very revealing ,let you know your components your using!!

Bob,

Your very correct, its probably is better to go with matching amps,that have identical voltage gain

makes a lot of sense,

I should have known that I took a little electronics at the College lol
