If Bi-Wiring is an option, should I choose Bi-wiring over single banana with free jumpers
Hello All!
Newbie here : ) I have a pair of speakers (MartinLogan Motion 40i) that have, according to the website, "dual five-way binding post speaker terminals which allow bi-amping or bi-wiring." As you can see in the top right photo of the speaker terminals in this link, the speakers came with free jumpers (the jumpers look like just a sheet of conductive metal) between the 4 terminals.

So when purchasing speaker cables, placing the best quality connection over cost, should I:
1. (Cheapest) Get single banana plugs and use the included free jumpers, or
2. (More costly but will it be WAY better?) Get Bi-wire speaker cables and remove the free jumpers.
3. Get single banana plugs, and find some high quality jumpers to replace the free included jumpers.
If it doesnt matter much to sound quality, it seems option #1 is best as its cheapest. However my goal is to get the best/most efficient connection so i suspect options #2 or #3 might be the way to go?
Many thanks for any advice!
As your speakers are around the same price as entry level speaker cables I would find the speaker cable that works sonically and compare the supplied bi wires from ML to a pair that is made by your speaker wire company. For any speaker at say 20K and up with associated complimentary amp I would always bi wire as sonically it is easy to notice the improvement.

@jsalerno277 "The reason is that an effectively larger diameter has less inductance since it has a larger cross-sectional area” - more important is how close positive and negative wires are, the closer wires are (twisting helps), the lower loop inductance of speaker cable is. |
@westcoastaudiophile Exactly. The specific product was a biwire Goertz Alphacore MI 3 Divinity, a 0.8” x 0.04” solid copper ribbon. The space between positive and negative conductors was only 0.4”. The dielectrics were Polyester Terapthalate and Teflon applied around each solid rectangular conductor. No twisting. They specify two things. They are a low impedance design. They state a Zobel Network may need to be installed in each speaker cable to stabilize the capacitive and sell this as an option. The network still created instability with the Krell/Apogee combo. I moved on to WyWires Platinum and have a completely new system. |
