What is "biwiring"?

In my world, using two separate cables for biwiring is better. I tried the single cable/double pair speaker termination approach. It was clearly not as good as utilizing two pair of cables.

Doesn't matter, spades or bananas. If there's four leads you can double up either one on a termination. With Bananas, you may need a couple plugs like Audioquest's double banana plug, to accomodate all four leads. Then, run one Audioquest double banana into the other.

Budget may decide which way you have to go, though.

If you have the cash, do the job right and run two separate cables, i.e. one for low freq. and one for mid/high.

And, while you're at it, buy another two channel amp, to feed these new wires! ha Now it's getting expensive. But WELL worth it! To achieve truly great results, biwire AND biamp each of your main speakers! I found that the combination of biwiring and biamping Maggie 1.6qr's makes them another creature altogether!

I'm currently using Harmonic Technology cables, and find them to be quite open and detailed, far more so than the Audioquest dbs cables.

Put a serious percentage of your speaker cable dollars to work on the mains. You can always upgrade your sub, satellite cables later.

OK, another question:
Biamping - do the 2 amps must have the same power rating?
For example, I have a NAD T753 receiver (6x70W) and an old NAD (2x25W) - does it make sense to biamp?
Thanks!

Plamenz, Your amps would have to have the same input sensitivity to function properly. If they are different you would have to use a crossover or some form of attenuator for the more sensitive amp. Not as simple as it sounds unless you use identical amps.

Newbee: "Plamenz, Your amps would have to have the same input sensitivity to function properly."

Well, sort of. The input sensitivity has to be the same for the same power output. Some reviewers (but virtually no manufacturers) test and publish input sensitivity for 1-Watt output, and high-power amps tend to have less voltage gain. If one looks only at published sensitivities at rated outputs, 2 amps could be different but the same. They're different in that one is rated 0.5 volts in for 50 Watts out while the 2nd is rated 2 volts in for 200 Watts out. They're the same in that they both have the SAME voltage gain--which means they'll have the SAME output voltages--for the same input, until, of course, the 50-Watter runs out of power.

If the 25-Watter is a receiver, it has volume controls so it sort of doesn't matter what its input sensitivity is, simply adjust the volume to have the treble balance you want.

Personally, this sounds like an exercise in futility to me, as the 25W. amp probably won't SOUND any better than the 70W. amp, and you'll be introducing the impurities of another pair of interconnects to the treble, but it won't cost you anything.

Good luck.

Thanks, this is helpfull - I think for now I will use the 302 for multi room purposes.
