I too am a year late coming to this thread but FWIW, about a year ago I pulled out my 10 meter QFil XLR between amp and pre and plugged in the Paragon Enhanced. It's still there. A little over two months ago I swapped my Valhalla bi-wire for Paragon Enhanced. Unlike Brainwater, there was no initial serious shortcomings... the speaker wires sounded awfully smooth and detailed ROOTB. However, last weekend I slid the Valhalls back in. The Verdict...the Paragons were easily 90% as capable as the Dost. The only performance area the PEs lagged in was three-dimensionality, and not by much and if I hadn't had the Valhallas as a longterm reference, no dissatisfaction would have been noted at all. We're talkin' a smidgeon here guys...no biggie. If I had to do it all over again I would definitely go with the Pure Notes. Value-wise, it's not even close.
BTW, the PEs couldn't possibly have more than 40 hours on them so I've probably prematurely judged them based on what others have reported here so I just might revisit them soon. I knew I was going to keep them all along so I didn't go into perpetual disco mode to beat out the 30 day ticker.
