Bi-amping for me?

Hi Russel; do a search under bi-amp. I just checked and there are about 30-40 threads on bi-amping-- probably a lot of good info. there. I'll just say here that Richard Vandersteen recommends passive (no external X-over) vertical bi-amping as an improvement over just bi-wiring with his speakers. His owners's manuals say nothing about horizontal bi-amp.

I'm going to passive vertical bi-amp my Vand. 3A sigs. next week when my amps are returned from up-grading. As you note, this is a controversial subject, as for instance, you would have four separate amplifier channels driving four different sections of your speakers, and this has potential for introducing "unwanted colorations". Ideally, your amplifiers should be carefully matched to avoid these potential varying colorations. During up-grade, SMc is matching my DNA-2 amps, and I'm just hoping for the best. I just made the decision that I wanted to do it and proceeded.

I believe it was A71spud who was very pleased with bi-amping, especially when he used an external X-over. Good Luck. Craig

.....as to amps with same output. With a vertical biamp the amps must be as nearly matched as possibe, and therefore, yes, they must have the same output. In horizontal bi-amp, ie where one amp drives the upper frequencies and the other drives the bass, the amps can be totally different, ie tube amps for the mids/treble, and SS for the bass. But be aware that these are difficult to match, and I know I'm not ready for it. Again good luck. Craig
