I'm not sure STUDIOS use this stuff, but recording engineers and roadies use it all the time for monitoring, as it's easy to work with and sounds great. I too have an EMC-1 SE, but probably will NOT blow another $1400 to have it tweaked by Empirical. Nonetheless it has such exquisitely natural top octave detail that I heard an improvement in going from Red Dawn to SPM on my Verity Audio Parsifal Encores. Yes, yes, I realize that 25' is a longish run, as I have 30 footers on my HT system surrounds, but there's a difference between applications here that makes me think twice about your options. Certainly you want enough copper to push the VR4 SEs from 25', with NO loss in rez or top octave detail provided by the EMC-1. Try the Canare, but I suspect that other high-current LINEAR cables MIGHT give you more life up top.
I very highly recommend the CANARE for budget systems, all HT, and for long runs for surrounds in any system. If you try it as an inexpensive first shot I suggest that you'll find it RELATIVELY very dynamic, but slightly softer on top than the most open, linear (Nordost, et al) cables, resulting in a neutral-to-laidback soundstage. It's indeed perfect for my Spendors in a HT setup, where most programming is too bright anyway, but with your (and my) 2 channel ref system just keep in mind its limitations. When I'm setting up friends' budget systems I start with it, then try Blue Heaven when more "life" is desired, but NOT at 25 feet. Keep in touch. Ern
