Just bought, B&W 804s RCD 1072, RB 1070 amp and RC 1082 Pre,
Just wondering if anybody is BI amping the 804 and does it make a differance?

Welcome!!
I've got a similar set-up (703, RCD 1072, RC 1070, RB-1080). I don't have any experience with bi-amping, but I'm sure others will pass on their opinions. Just curious, instead of spending more money on another amp, did you consider just getting a 1080 instead of the 1070? Also, there are a lot of fans on the 1092 and I would imagine the 1072 soon too (even though it is only 100 W, a lot of users swear by their 1077 over their previous 1095, so I'd expect the 1072 to be similar).

Again, welcome and have fun with the system!! :T

I've been dealing with the same store and the same staff for more than 20 years and they believe that Bi-amping will be the way to go with 2 1070s. I bought just the one for now, you know the, WAF(wife acceptance factor).I'm just trying to see if anybody has gone the bi-amp route.
Thanks for the reply..

Using one 1080 will probably give better results than 2 1070's.

Welcome to the club!

You'll find a few people who find passive bi-amping worth the money, but the general consensus is it barely makes a difference.

Truth of the matter is the woofers in the 804 are going to require more power then the 1070 is capable of producing, never-mind the mid and tweeter. Even when you run a single 1070 on just the woofers (bi-amped), you're still going to need more power. Going with a single RB-1080 will allow more power to go to the woofers when needed. Most people find the 1080 sounds a lot better then the 1070, so that's another benefit.

Heres a link to a website that explains how and why passive bi-amping is the correct way to bi-amp.

However since the woofers are taking the lions share of the power, going with a bigger amp would be the best choice. One major benefit of bi-amping though is that the woofer amp can be driven into clipping, which most likely will not be audible or necessarily harmful, its not a good idea though. Since you're using a separate but identical amp for the high frequency section of the speaker it most likely will never clip and therefore there is no chance of damaging a tweeter.

Thanks So much, I will take a second amp home for the weekend, and give it a try.
