Supra wire impressions vs. WE/Dueland wire

I have been using Mogami 3103 cables for my 25' speaker runs and have had no complaint with my McCormack SS amp and Spatial Audio M4 speakers.  Intrigued with the extensive reviews of the WE/Dueland wire on Jeff Day's blog, I had my pal wire me up a pair of 1 meter IC's with the vintage 20 ga WE stranded and tinned copper cloth-covered wire.   While they don't quite eke out the inner detail of my $600 Von Gaylord Lemaa IC's, for 1/10th price, they are very musical and I could live with them in my system happily.     

I recently got 50' of Supra Ply 3.4 speaker cable to compare to my Mogami wire.  The Supra cable is similar in construction to the WE/Dueland wire, but with a PFTE jacket, which I need because I run the cable in the crawl space under my house.  Both cost ~$4.00 a foot.  My take is that this Supra wire really is a worthy SQ improvement in my system.  Before I hooked up the Supra wire, I felt I needed the LF of a subwoofer, but not with the Supra cable.  It is overall well-rounded and very detailed, with excellent extension. It is clearly more involving than the Mogami cable.  It is far more lively.

So, if you are interested in checking out this "old school" tinned copper wire that Jeff Day has written so extensively about, you might find the various versions of the Supra wire similar in performance to the more expensive Dueland/WE wire.  The pedigree is quite similar.
