Signal Ultra vs. Straight Wire Symphony w Tubes

Recently moved forward on some upgraded entry level speaker cables. Purchased a used pair of bi wire Signal Ultra cables. Unfortunately, they are shorter that advertised and I have to send them back.

I did try them out first and it was a huge upgrade from the makeshift bulk cables I had been temporarily using. Better detail more bass and a big warm sound stage. 12-1 o'clock gives me the volume that 2-3 did before.

I've heard the Signal can be a little veiled but it just sounded warm and really nice, especially compared to what I was using. I'm considering ordering a new pair in the right length.

Wanted to see if anyone can compare the sound of the Signal's to the Straight Wire Symphony? I like a slightly to the warmer side of neutral without losing detail. Hate real bright or harsh.

Have a Rogue Cronus Magnum and LSA Signatures.
