Ron,
I was able to demo the sort fut, and as I said it did make a significant positive difference. The downside is the price. I have sort kone TC under my amp and preamp.
I did not try the other Nordost speaker cables before purchasing the Tyr 2. I bought a trade-in pair, which I did take home and try, then kept them.
The pricing on the trade-in pair was too good for me to consider another Nordost speaker cable choice.
I jumper the speaker cables per my dealer's recommendation with the Nordost Reference bi-wire jumpers.
I have 2 pieces of Valhalla 2 in my system, a tonearm cable on my primary turntable and the AC cable from the wall to my QB-8. The interconnects are Tyr 2 and the other AC cables are Frey 2.
Thanks for the comment on the album wall. My wife helped me with that and we both like to look at it. The lady on the cover of Whipped Cream is still around and lives in Seattle area according to an article I saw a while ago.
I hope you enjoy you Proac speakers as much as I enjoy mine.
Best Regards,
Jim Perry
