Bi-amping using RB-1092 (or RB-1090)

[Mark-n-b]

Has anyone had any experience bi-amping using an RB-1090 or RB-1092? I originally posted this in the B&W forum, but it may have been better placed here.

I am building a 5.1 system for 50% movies, 50% music (both 5.1 and 2.0), and I am thinking of 4×802D & HTM1D or 4×803D & HTM2D - I have not decided yet.
I was thinking of running these with 5×Rotel RB-1092 in Bi-Amp configuration - the reason being that I cannot afford the entire outlay in one go - so I will be buying the bits over the course of a couple of years.
This seems reasonable to me, because I can start with 2 channels then add the rest later.
What do you guys think about this? Has anyone heard this setup - i.e. RB-1092 bi-amp to 80*D?
Cheers,
Mark

Why not just bi-wire the 1092? 500watts should be more than enough.

Bi-amping wont provide more watts. The speakers will still "see" 500 watts.

Why do you need 500 watts per channel ? The RB 1080 (200W) is not enough ?

Obviously imbeaujp you have little knowledge of the B&W 800 series - they thrive on more power! The RB-1080 simply won't cut it.

Hello! Do you say that you did try this and did not find any improvement?

Definatly more than 200W, I find my self using the extra power reserves of the rb-1090 often and thats with paradigm studio 100v3's.

You could buy 2 rb-1092's to start off with, see how they go in stereo bi amped then try one on its own in stereo. If you beleive the bi amped configuration is better than buy another 3 rb-1092's, if not keep the 2 rb-1092's use one for your mains and the second one for the surround's and add a rb-1091 mono for the centre.

Hi Mark,

Yes.
I have connect one RB1092 only for the lF and the ohter for HF, RB1091 always for center and one RMB1075 for rear(only SR left&right - 5.1)

No improvement in LF, HF with some 'best in any event not worth it.
I linked in bi-wired and are pleased.

Evidence has to connect stereo test ... then tell me about..

It's hard to imagine a speaker needing more than 500watts and once it reaches it's peak, I doubt there would be anymore audible improvements.

Digital amps need a week of break-in time. Give it a week and see how it performs.

Thanks to everyone who has offered advice and comments - it is much appreciated!

I must admint that I do not know the specs but it seems to be less efficient than my http://www.thevintageknob.org/YAMAHA/NS1000/NS1000.html that are 90db 1W/m.

But I listen to them a couple of times.
