jafant,
In response to your question about my StraightWire cables, I was using Encore speaker cables and Rhapsody II (RCA) interconnects in my system until just a few months ago. After switching to a PS Audio Stellar stack in early 2019, I decided to try several moderate-priced balanced interconnects in my system. Using XLR's from the Cable Company lending library, I decided that the Cardas Parsec XLR sounded better in my system than the Rhapsody II RCA I already owned (2nd place), Shunyata Venom XLR (third place), or Synergistic Research XLR (fourth place). I'm now using the Cardas XLR between my Gain Cell DAC/Pre and my M700 monoblocks.
When I replaced the interconnect, I did not replace my StraightWire Encore speaker cable. Based on my room configuration, I have speaker cables that are 24 feet long and run under my living room floor. This arrangement makes replacement of the speaker wires quite expensive for reasonably good wire, so I'm keeping my StraightWire cables for now. Fortunately, the folks at StraightWire tell me that the Encore cable remains a very solid choice for my Thiel 2.2s and that even spending quite a bit more money would only get me small improvements in sound quality for my investment.
