Actually, I was in the same quandary about 6 months ago. I was hot to buy the Nordost Purple Flair based on briefly hearing it a few times, and before some reviews came trickling in.
Unfortunately, I need at least an 11 ft pair and that was expensive even with a local dealer's discount
However, I thought it might be more economical to go with the White Lighting model But I chucked that idea out the window, and like yourself decided to go further up the Nordost's new LE line, and considered the Red Dawn speaker cable
Interestingly, one of customer service reps, claimed that the Purple Flair was the best value for the buck in the new line. So,far, I have done nothing and am still farting around with an entry level pair of Audio Art SC5 speaker cable I bought about 1 year ago. Not bad, but I know my system deserves better.
I was just about to introduce a new thread about the chaos of budget cables popping up every freakin day. So as Danlib1 suggested just relax and listen to the music.
A reputable audio dealer will generally bend on returns, but I have a hunch you will really like the Nordost PF. Let us know what you experience with them is. If you rave about them, I just might buy a pair of the PF's and be done with it.
