biwire trick

Good for you for experimenting and trusting your ears.

As long as nothing blows up, or now has a reason to, why not (thanks Al)? I was piqued by the Nordost write up -- to attach the leads to treble and mid from a single cable. In their case they fill the gap with their jumpers, but it seemed like they were essentially balancing the current load. Biwire, in principal, should do an even better job since it would be truly balanced.

No idea. I wouldn't have posted it if it didn't make a difference. Even Nordost doesn't know why it works. IOW, theory can kiss my axx.

Oh, and always, YMMV

Forgot to mention that all 4 runs are identical in length and type.

Tvad is absolutely right about education - knowledge certainly does instill principles about the right way and wrong way to hook up electronic equipment.

All I am saying is that from a "best practice" perspective it is wrong to use speakers wires with a large + and - wire separation to create excessive induction in a part of the system circuitry that is supposed to be as transparent and loss-less as possible.

Of course you are all free to do whatever you want. If an odd way to hook things up happens to work and you like to do it then great - it is not wrong from your individual perspective with your system as it just happens to sound better.

However, on the whole across all the many systems world wide, your approach is not best practice and I would not recommend it (and that is what I was trying to say). The global standard of selling speaker cables in jackets with two closely adjacent + and - wires is still the current best practice and the "right" approach to get the equipment to perform according to the manufacturer's intent.

I know Al will agree with me on this one, as he is a EE and all audio equipment is designed to be hooked up with connections that are as transparent as possible.
