hifikrazy:OK, so I just concluded a listening session, the main purpose of which was to determine if biwiring works on my system or not, thereby determining my choice of single wire or biwire when I upgrade my cables.
The sad result (for my wallet that is) is that biwiring is clearly better. If you recall, I'm currently running QED Silver Anniversary XT Biwire, so all i did was to remove one pair of the connections from each speaker and connect the links. .
Based on my experience* you should retry this test, using first your bi-wire configuration, then connect up you cables to make single runs of parallel line & connect the jumpers at the speaker end. I doubt you will hear much difference between bi-wire and doubled-up single run.
If this is the case, don't worry about bi-wiring, just get some really good quality OFC wide-gauge cable for a few quid per metre and bask in your achievements. Honestly, you might be amazed.
When I got my first system (second hand) it came with some pretty ugly Linn K-20 speaker cable. This is heavy gauge, unshielded copper stuff and I felt compelled to get some decent 'hi-fi' cable. After reading a lot of reviews I settled on QED SA XT with airlocks. 50 quid for a couple of metre stereo pair! The best way I can think to describe the difference is that the Linn stuff was bold, easy and full, whereas the QED was squeaky and lean. Lo-tech won out over hi-tech.
I would be interested to hear how you get on.
* Caveat: limited, biased & possibly ill-informed; but it works for me and took an age of trying this 5* product and listening to that 5* advice before I actually did some research on this. Then sense prevailed and I started to enjoy hi-fi again!
