I don't think it's the cables, IDKW but single wiring with good quality jumpers has always sounded better in my systems. Doesn't make sense I know.
Maybe ask Townshend if they'll take the cables back and change them for Fractals.
Townshend Isolda Speaker Cable BI-WIRE issue
I recently tried the Townshend Isolda speaker cable and I was blown away. I love it. So much I bought a second to Bi-Wire them together as that is how I had my last cable setup.
However, when Bi-Wired, the system breaks down in audio quality. The bass extension is lost, and the music feels like something is missing. Almost like entire frequencies are missing. It's strange.
I did try both cables separately, to confirm that both cables were good on their own, and they are. But when Bi-Wired, they don't sound anywhere near as good. For the record, I am using PS Audio BHK mono Amps with Revel f228be speakers.
Does anyone have experience bi-wiring the Townshend Isolda speaker cables? Any ideas why this could happen? Any suggestions? Any science?
