Can you share more on the parenthetical "icing on the cake" part please?
I'm currently down the rabbit hole, looking up, and optimizing my streamer==>DAC==>BHSE==>009 system, with psvane and stock tubes.
I have 'meh' cables right now (belkin usb, low end audioquest balanced interconnects) and just took the PSAudio power conditioner out of the loop to get back to a baseline.
Over the years with testing a number of high end cables in speaker and headphone systems, I ended up really liking the Stealth Indra and Sakra cables, especially in the bass, where there is a transparency that I haven't heard in any other cables.
They also seem to remove some level pain from the upper highs, making them rounder and fuller. I tried this on several speakers like Khama 3.2s and Harbeth SHL5s and SF Cremona Auditors.
But they are neutral cables, and in some situations, I like Cardas Golden Cross ICs to subdue, maybe even roll-off, the highs. The Cardas is refined and still keeps things tight and controlled, and just sounds musical.
Synergistic Research cables are also nice, but not as refined as the others.
For some reason, I like RCA over XLR ICs on my 007t / SR009 combo (more mellow).
My favorite power cable for digital is the older Shunyata Anaconda VX (still around used sometimes on audiogon) (the Anaconda Alpha Helix from later on is also very good).
The Shunyata power conditioners also remove fatigue in all systems I have tried. The Hydra 8 and especially the Triton are what I like.
I didn't like the PS power conditioner (regenerator) I tried -- it was too hyped up. (A PS300, but that was 10 yrs ago.)
