I'm going to chime in with my personal opinion regarding cables. I am not playing on the same level as many on this site, but my system is decent and transparent enough that a power cable change for example is obvious. I believe a system is about synergy and balance. I don't believe in the full loom idea too. Play and choose, if you feel you need more bass, add a bassier cable. If you feel the sound is slightly veiled and dark, try a more resolving cable. To think that there is a perfect cable for all equipment on all systems is wrong imo, and on top of that, incredibly boring.
FYI, I am using Dave's DSR XLR interconnect (the silver ribbon one) and I had some a/b demos from more well-known brands (Tellurium Q, Chord, Wireworld and one more can't remember). Some had more 'bloom' and darkness, you might prefer that. Or shall I say, your system might benefit from that if your equipment is going in a more resolving direction than you might want. For my ears and in my current system, this was the cable I chose because it was the one that I felt delivered the best experience for me. From the ones I tried though, this was the one that felt like the 'veil' had been lifted the most. It brought me closer into the music. My T+A integrated is slightly on the warmer side, as well as my Holo May dac. My speakers are the Focal Sopra and I don't get any high-frequency problems with Dave's silver cable and beryllium tweeter. Do I feel this is the perfect cable? No, because I don't believe there is an ultimate 'be all end all' cable. Listen to your system after taking a break from listening for a few days, and you will know if you want a 'fuller' or more 'resolving' sounding cable. Chef in the kitchen, as they say.
