Is Bi - amping worth the trouble?

Zormi- Try to see bi-amping as a remedy. That is, something you apply in an attempt to overcome some shortcoming or failure in your system. You have brand new equipment ready to install in an unfinished room. Why not put it all together and see what you have before introducing change? You may not need or want to do anything at all.
Not all changes (mods) are improvements. And audio is not purely additive. More can be worse and less can be better.
Take your time and alter things gradually and, above all, one at a time. Fast changes make for slow progress and slow changes make for fast progress.
The only places where bi-amping is really useful are in powered speakers where the amps are onboard and dedicated to their assigned drivers OR in speaker systems specifically designed for use with an active crossover and multiple outboard amps. The rest of this stuff is just toyboy nonsense.

Hello Zormi,

Though I always recommend biamping I would agree that it is best to finish your room and listen to your new system enjoy each step of the way....
I am also finishing my audio room these days! and am also waiting to try new things I have a pair of subwoofers I want to try as a biamping alternative and probably a new better transport! But the first thing will be to listen at my system as it was when I took it apart.

Thanx for inputs guys,

It seems the best to try all options, step by step... And I would do so, surely. My main concern was the UNSPECIFIED (in specifications) gain factor of both power amps. I am curious can I derive somehow the gain factor basing calculation on other available specifications...

Halo A21 mated with Primare PRE30 achieved stunning results driving a pair 803S. I consider my new 802D as much more difficult task for the power amp - that's why a new RB-1090 reinforcement in my place.

I'd say the 802D's eff is greater than the 803's eff... 92db vs. 89db (?)... so it would seem an easier load just by that account. I had several pairs of BW units and thought the Bi amp path with them a slam dunk. Seeing the above postings about the various paths to that end, tells me differently. I also spoke with the Tech support head honcho across the pond about impedances and such... BW does things a bit differently in how they measure things along those lines according to him. You may want to get in touch with him via the BW USA WEBSITE SUPPORT TAB. TO GET A BETTER UNDERSTANDING...

I do know of at least one tech rep for an entirely different company that was using a 60 wpc CJ tube amp to drive the 802N's, and he said he loved the sound.

Though what has been said about bi amping being a task to remedy a problem may well be sage advice... then directly afterwards is another take opposing the previous one. Finding out what one has first is a slam dunk common sense thing. Fashioning a system the way you want is your own choice. Always. In this thread alone, there is significant info for your task, and it's not the only resource. There are some quite worthy efforts posted here so I do hope you enjoy your pursuit!

Read the entire thread, still need advice from the pro's here.

Short and sweet...Running VR-4 Gen III's, Aesthetix Calypso, Parasound JC1's.

I may have the opportunity to purchase another pair of JC1's at a very reasonable price.
VSA does not discourage passive bi-amping using the speak's xover, in fact, Albert seems to encourage it. This may seem like total overkill to some, but I like my music to grab me by the throat and nuts at the same time.

So, four identical amps, vertically and passively bi-amping VR-4's.
Is it worth it, should I try it?
