Need Advice on Amp Setup w Vandies--Arcam/Bryston


Hi,

Here's the scenario. I have been using my pair of Vandersteen 2 Sigs with a 2W for stereo listening for some time in my "nicer" system, with a more modest 5.1 setup running in a different room off of a receiver. I am moving soon and will be combining my 2-channel and 5-channel systems into the latter for the time being. I have a VCC Sig for the center and will pick up some VSMs for the rears. Right now, I am using a Bryston 2B-LP for my 2-channel amp. While it is very good, I have been wanting to upgrade it anyways. Long story short is that I am in the market for a multi-channel amp.

I have yet to run my 2 Sigs bi-wired, as they are truly meant to be (or so says Richard), instead having single runs of Transparent Ultra with jumpers. I am looking at either a Bryston 9B SST/SST2 (as money and availability on here will dictate), which would put me back into the same realm of using single-run cable unless I switch. Alternatively, I was considering a 7-channel amp (Lexicon GX-7, Cary Audio, or the like) and bridging or bi-amping the L/Rs (but neither lets me do this unless the answer to the following question is yes). Question--do 7.1 processors allow one to do a 5.1 setup and send the same signal as L/R to the extra set of outputs (to have bi-amp channels)? Looking at an Arcam P7 or P777, however, with their loop-throughs, I could feed it from a 5.1 processor (the outs of my receiver) and move to a true bi-amp and bi-wire setup for the Vandersteens (I will get new cables but not on the level of the Ultra, probably just good wire). I am looking for input as to which setup, the 9B or alternatively good 5-channel amp with single run Transparent cabling) would compare to a perhaps not quite as good but still very decent amp with a bi-amp and bi-wire setup with lesser wire.

I know that listening is everything, but my local dealer probably will just have an A38 available that I could then feed out to a 3B for comparison. I know the A38 won't be as good as a P777 would be. I actually did the same many years ago, and that is how I decided on the 2B, as opposed to using Arcam amplification (used their CD and preamp instead). Kind of long-winded, but I appreciate the advice more on how the Vandersteen will perform in the bi-amp and bi-wire scenario. 9B=150W jumpered to highs and lows; P777=150W to each high and low driver via separate cable. Thanks.

Using 4 channels of your multichannel amp is a vertical biamp. The idea is to work the amps the same amount. With a horizontal setup the amps are under a different load because they are powering different parts of the speaker. Under those conditions, the amps sound different from each other.

As far as double biwiring goes, I'll tell you about the results I got in my system. I use The Cable Co. for all of my cables and accessories. They sent me a pair of internal biwire of Audioquest Mont Blanc and some cables other than AQ. After listening to them all, I chose the Mont Blank. I think they went for about $1600-1800. I had a question about the type of spades they used so I called AQ and told them what I was going to do. Audioquest recommended I use 2 separate runs even if I went with a less expensive cable. I ordered 2 pairs of CV-8. (About $1200 for both sets). AQ messed up my order and sent me 2 runs of type 6 instead. (about $400 for both runs and only because they were factory terminated. Type 6 is a bulk cable). They let me keep them until I got my CV-8's. The 6's were much better than any of the other cables, including the Mont Blanc. It wasn't even close. The CV-8's were a little better, but had I heard the 6 before I committed to the CV-8's, I would have kept them.

Albind recommends the Audio Perfectionist journal. I agree 100%. Its a must have.
I agree with ZD.... I found that separate cables for Bi-Wire work best with my Vandersteen 5A's
Yep, just got a pair of 2ci's last week (sellin them this week, that's just they way I am) and experienced first hand that bi-wire is the way to go. Big big difference.
