SDA Perfection

Thanks to some great posts on here concerning the importance of component interconnects, speaker wire and the sda interconnect cable and then after reading Matt's white paper on SDA and the Surroundbar, I'm getting ready to try one more upgrade which I hope will perfect the sda imaging to it's greatest potential.
Theory: To get the crosstalk cancellation that Matthew intended, my SDA interconnect cable must be constructed of the exact wire that my speakers wires are constructed of!
Why? The signal/sound that the opposite speaker is trying to cancel out must be as exactly inverse as possible to effectively prevent the sound from the right speaker from being heard by the left ear and vice versa. Thus when I went from stranded speaker wire to solid core and heard it's effect on clarity, preciseness and separation, a little light bulb went off in my little head. I was still using 10 guage stranded for the SDA cable which meant the inverse signal that was getting to the left speaker was not the clear precise signal that was coming out of the right speaker and vice versa.
To remedy this, I have to construct a SDA interconnect cable made of solid core wire just like my speaker wires are made of.
Has anyone tried this already? I'm going to try it as soon as possible.

The placebo effect alone should show you great things. Good luck.CTC BBQ Amplifier, Sonic Frontiers Line3 Pre-Amplifier and Wadia 581 SACD player. Speakers? Always changing but for now, Mission Argonauts I picked up for $50 bucks, mint.

I haven't done it yet. That signal is midrange only. If there were any differences my guess is it might clean up placement of instruments? Who knows. It sounds reasonable to want a similar wire as your cables though. Let us know if you try it.

Avantgarde horns, 300b tubes, thats the kinda crap I want...

It surely isn't going to hurt anything, and you will at least get a better connection.
I am using the same cable as you have mentioned in my set up, same length as both speaker cables as well. Can't really say for sure if it actually made a huge difference, as I didn't have the pin/blade cable to do a side by side.
But it made me feel better

It makes sense to me to have the IC constructed of the same wire as your main speaker wire, let us know how it works out...Source: Bluesound Node 2i - Preamp/DAC: Benchmark DAC2 DX - Amp: Parasound Halo A21 - Speakers: MartinLogan Motion 60XTi - Shop Rig: Yamaha A-S501 Integrated - Shop Spkrs: Elac Debut 2.0 B5.2

Only on certain SDA's is it midrange only. My SDA2's have the SDA tweeter in each cabinet as well, so it would have to be a full-range signal.Ludicrous gibs! -
Correct. The older 1st & 2nd generation SDA's utilized an SDA tweeter.CTC BBQ Amplifier, Sonic Frontiers Line3 Pre-Amplifier and Wadia 581 SACD player. Speakers? Always changing but for now, Mission Argonauts I picked up for $50 bucks, mint.

Sounds like fun. Don't forget to change the wiring inside the box.
