Tom- I’ve been using Strait Wire Serenade speaker cables in my system since before I had Thiels. I actually first used them with a pair of Meadowlark Kestrels. When I got my 3.5s I noticed how much larger and more dynamic they were over the smaller Meadowlarks but still retained a certain familiarity and naturalness to my ears. I attribute this in part to both manufacturers design philosophy of time & phase alignment. Later when I acquired my 3.7s and to this day I continue to listen through my SW Serenade speaker cables. I like the fact that these cables have been with me so long and have always allowed me to hear the sometimes subtle differences when making changes to my system. It makes perfect sense now that I know the history between Thiel and SW, that these speaker cables have been such a synergistic match with my Thiels.
Cheers!
