I have been with Alex since he started, I was in the beta program 8 years ago?
Now all updated to current 'Silver" series, it can get very expensive quickly. Everything here is all Wywires must be a bit over 5K, I don't even want to think about the "Diamond" Series.
Yes I also have all the usual suspects in the arsenal here too. Belden 8402, Duelund and, WE 16 Ga and the 20ga Duelund Interconnects, Mogami 2549 and more. These are very good cables of course all flavored different.
Very personal and too tough to really recommend because they need to be tried in the system.
For instance, depending on the wire, speakers need to be re-positioned, a tube change may be in order too. On and on to your taste. You have to stop sometime.
