Anybody have any experience with these? I have read some reviews and most of them talk about how muddy these interconnects can be.
I use two pairs in my TV setup (not home theatre, just TV). When I tried them with my hi-fi rig I thought that they were surprisingly very warm, but not muddy. A smooth tube-like sound. It was really great on one of my tuners. For $20.00 used what do you want? They would really be a great alternative to Kimber PBJ for instance. The character is so completely different. Either one or the other would work, but probably not both.
