Most importantly I've found that the ICs between the turntable tonarm cart leads and phono stage/SUT to be the most critical in terms maintaining distance from PCs in order to reduce noise. There are less noise implications I've seen with ICs related to DACs and linestages and amps....especially when using XLRs.
“supporting cables cannot possibly make any difference.”......what a BS!
Yeah forgot the doc said double up on the Xanax before reading audiophool forums. According to him, if audiophools blather blather it works, and also works equally well when they miss obvious sarcasm.
Audiophools are like Drax in the first Guardians movie: "Nothing goes over my head. My reflexes are too fast. I would catch it."
Thanks for starting this thread. One can be in this hobby a long time and forget some of the dos and dont’s.
Case in point (no, I’m not Rod Serling), I raised my cables a short while ago and heard the benefits. Then, I sold my beloved Barcelona chairs with matching ottomans for a recliner I could get in and out of easily, and fiddled around some more behind the audio stand.
Listening while trying out my new recliner, I notice the soundstage was lower and the lows were weak and not as focused compared to before. I checked everything with my laser and my head was only about 2-3" higher and just couldn’t settle on that being the answer. I could slump down and nothing improved. It was after reading this thread that I took another look behind the rack and saw that two pairs of ICs were now sitting directly atop two PCs, but at right angles.
I got some of that insulation made for tubing with the slit down the side and fashioned some short pieces to wrap around the PCs, raising and isolating the ICs from them and viola!
The soundstage is now as tall as it used to be and the lows are back and impactful as ever. To quote Billie Eilish, Duh.
All the best,
Re: OP When back on its support, the IC is about 4" apart from the PC.
I doubt if there’s a formula for separating cables. As much as possible within the limitations of your rack. Also, if an IC is on top - or underneath - a component, be sure it isn’t laying adjacent to the power supply inside the casing. That’ll affect the SQ, too, (I assume that most know that IC’s should not be run parallel to PC’s. That could cause hum or some other weirdness.)
The rat’s nest behind my rack has a variety of supports for keeping the cables separated. Primarily, I use clothespins. Also, very small C-clamps on the rack shelves and assorted rubber doodads from Home Depot.
For supporting the speaker cables off the floor in front of the rack, I found a pair of decorative props from TJ Maxx/Home Goods.
