It will sound different, but not sure if it will sound "better".
As @zlone stated, you're going to have to try it to find out. Generally speaking, a full loom of cables tends to have more synergy than mixing/matching.
Basically happy, but…
I’m pretty well set with mostly Transparent Gen 5 Ultra speaker cables and Ref pc’s However, I still have a legacy Syn Research Copper Element RCA between my Chord DAVE and Pathos Heritage MO ii Intgrated. It was a great cable “in its day” but I’m wondering if an upgrade will have a noticeable impact on my sound. I would probably go with a used Transparent Gen 5 Reference if I make a change. Any thoughts?
