Anybody try doubling different cables?


It seemed logical to me,to try to get the most cable between the amp and speaker for best performance, so have double runs of Clear Day solid silver and Acoustic Zen Double barrel - an effective awg of about 5 or 6? - and they sound spectacular - better than each individually. Interested to hear the experts' opinions or anybody that has tried similar set-ups with copper plus silver of different manufacture and design and resultant increased gauge wire?
Not hard to connect with a combination of spades and bananas on both ends- double spades and one banana per amp side and 4 per side on the biwired speakers.
System: EAR 868 preamp, SOTA 4 turntable, Bel Canto mono 1000 ref amps, SP Tech rev III speakers, Mcintosh MR 67 tuner (better than my ss CDP!!) KCI silkworm +, GG reflection, Cardas GC, Mogami neglex gold ics, Pangea 9 AC SE pcs.
Thanks for your input.

Last year,member Nonoise wrote a post about using the Clear Day speaker cables with other(cheaper) brands of copper speaker cables.

I have used the Clear Day Doulble shot-gun speaker cables with a DIY 14awg copper speaker cable. The two speaker cables used together were the best I have had in my system by far.

The combination of Silver Clear Day cables with almost any copper speaker cable will sound outstanding to very good.

The Doulbe Shot-Gun Clear Day cables were better sounding then the single shot-gun Clear Day cables when combined with the DIY copper cables.

BOTH WERE VERY GOOD SOUNDING.

But the Doulbe Shot-Gun Clear Day's were much better in every aspect of sound.

The short of it, I lent my son a set of Audioquest Flex 4 cables, about 8 ft. This is a quad run of stranded cable for custom install, nothing fancy but sounds nice. He wanted to upgrade and I convinced him to try GBC cable from HCM Audio, essentially soild copper Audioquest Type 6 wire now sold in custom lengths. Out of the package, GBC had more detail but less musical than the Flex 4 wire run as internal biwire. I suggested he run them both at the same time. Wow, sounded a lot better than either wire alone, more of everything, even volume (controlling for this effect, still sounded better). Remember this only 8ft runs. In this case, more wire and a combination of stranded and solid cable sounded better than single runs of either.

In my pre-2010 system, I have AR9's with Synergistic Research Resolution Reference X shotgun cables, which I jumpered together at the speakers (effectively making a double run). This greatly improved the sound and was better than a Telsa Precision Reference cable I purchased/compared/sold.

In my post-2010 system, I have Quintessence Summit speakers with SR Tesla Apex. With a single cable run, the sound was a little veiled. I added a second run of Apex and it made a huge difference.
