2. cables

Possibly dumb question: can I use two cable runs for each channel, not bi-wired?

I'm moving my components into another room, in order to shorten the existing 30 foot cable runs to about 10 feet,
and will run the cable through the wall between adjoining rooms. I'm wondering if I can make use of the resulting "left-over" lengths of cable by doubling up each run, utilizing one pair of binding posts for each side. Has anyone tried this? Question #2: should the pairs be jointly terminated,or should I use bananas coupled with spades, so that there are 4 terminations at each post? I haven't sen any references to this in the past, so it may well be in violation of some basic rule of physics, but I thought I'd ask, anyway.

Simply doubling wires to the same terminals does not double the impedance. It halves it. However, since he mentioned he was using shorter wires, for example say to half the original length, the impedance would be the same as before.
Dan, I’m not sure I follow the last quoted sentence. Cutting the length in half would cut the resistance, inductance, and capacitance in half. If the wires are then doubled to the same terminals (i.e., paralleled) that would cut the resistance and inductance in half again, to 1/4 of the value of the original single run that was twice as long, while doubling the capacitance to the original value.

I've been a member of Audiogon for many years, but don't usually follow the forums. Recently they started sending me weekly updates on " Top new discussions ".

Maybe you all know, or the OPs system is posted somewhere, I looked, couldn't find it.
I'm surprised nobody asked what cables they are and what speakers. Depending on the cables this would be simple to give a reasonably definitive answer.
So, if this topic is still active, could you answer those questions?

Hello there,

I did try bi-wiring my speakers with a combination of different cable brands (VdH C122 with bananas and Kimber Cable 8TC with spades)
While the Kimbers worked fine by themselves and were my main cables for almost 4 years, the addition of the VdH´s gave the mix a bit more body and calm.   There is certainly a sonic effect by bi-wiring. It all comes down to your system and personal taste I believe.  Trying cost nothing and can be lots of fun! Enjoy

2 cables to each post is called Shotgun  Very worthwhile

I've done it for yrs with very good results. I have two pairs of the same gauge, same maker. Bigger,cleaner sound with out it beine bloated or heavy soundind. Seems to work best with big power amps,200 wpc or more.
