Is Bi - amping worth the trouble?

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?

You are currently getting almost everything your speakers can provide. Someone suggested moving up in the VS line. I suggest moving beyond it. Both ideas are going to give you more future upgrade options than you will see by trying to squeeze your current speakers for the last two per cent they might have in them. Bi-amping your current speakers means driving into a cul de sac. The only way to go from there is back out.
Besides that, it's a little like putting a spoiler on your Neon.

Blindjim, I have the VR5 SE's and just finishid biamping them, I have a Vac Phi 110 driving the tops and a Spectron Musician III driving the bottoms. Was it worth it? Absolutely! I love the Vac amp but it just didn't have the bottom end I wanted.I bought the Spectron and tried it by itself with the 5's "great bass" but it couldn't touch the Vac in the mids and high's. One thing I noticed when running them seperate was that the Vac played a lot louder at the same volume setting, later checking gain I found the Vac to be about 10db louder.I put a pair of Rothwell 10db attenuators between the pre and the Vac and that seemed to solve the problem. Maybe I was lucky but I found no other problems and the system never sounded even close to what I have now.
