With bi-amping we are talking mono blocks or if you figure two amps to work so that one works as a pre-amp so each amp is sending a different signal but with a single amp I can see why people are sceptical as to it's benefits of bi-wire as both cables are coming out from the same amp speaker turminal. When I first got into HiFi I will admit to thinking that you needed two sets of turminals to bi-wire your speakers as I thought at the time that was the only way you could do it and also I couldn't see how two cables coming from the same turminal could split the signal, I now know better.

So the differences are down to the impedance/capacitance/inductance changes. With my kit LS3/5a a few years ago, I connected them conventional. Then I unscrewed the backs and connected both drivers to the same binding posts. With my more recent 12PW/7P combo several months ago, I bi-wired with the same cable type and length. When I pair the 11MS and CHR-120, I will bi-amp with two pairs of Proprius so that I can alter their levels independently without resistors and so the inductive effects of one coil don't affect the other coil. Can then double-DAC if I want to do digital filters.

Interesting what you say Jon about your speakers, I have Silver 100s I wounder if it would work them, as in the past I have read that certain brands of speakers do respond well to Bi-wiring and others don't, the artical I was reading did touch on this subject. I think first I will look at bridging as my priority on spending is going towards the turntable up grade and new glasses which I'm probably going to need after my eye examination next week.

I found my MA Gold speakers sounded better bi-wired for about 4m but then decided to move the amps close to their respective speaker and I used 1m cables.

Thanks Graham. I need 7 metres to reach my speakers due to the way the room is laid out, so doubling up probably wasn't helpful.

I have heard a system with & with out Bi-amping and there was an improvement with two amps but saying that it was not big and the cost of the 2nd amp was well into four figures and the man demoing the system said to us that Bi-wiring would probably get you near not by much, to the improvements that it made, when asked would you get an improvement on a system costing a lot less than this set up he said on a more budget friendly set up you were better off bi-wiring but as with bi-amping not all speakers respond well to it, he said that he had heard speakers that to his ears sounded worse with bi-wiring. The demo was worth the few hour that I was there as I leant a lot from him as he just didn't demo equipment he showed us how to improve on what we have like speaker placement, stands & racks.

Agreed. And, notably, all of the best speakers that I have heard here have only offered a single pair of connectors. Bi-wiring was only possible on a few models at the (shall we say?) more value-orientated end of the market.

The LS50, as discussed elsewhere, is a good case-in-point. IMO it is in a different class to many "value-orientated" speakers I have heard in the past. It is not bi-wirable. No amount of bi-wiring (or even bi-amping) on less well-designed speakers is going to get equally good results, but bi-amping is likely to be more expensive.
