Has anybody tried using single solid core cables?

My entire system is solid core AQ stuff, and it works as advertised. Some things in cable theory make sense, and others not so much (to my addled brain anyway), and spiraled solid core done well does make sense as a noise reduction idea. Anti cables work well for some people, but the fragility of the merely painted bare wire seems dangerous territory so my rig looks like it's being attacked by bungee cords...and that's fine with me.

Type 8...bought used. Haven't tried the DBS stuff but I assume it works well.

I use Diamondback XLRs for balanced runs from my DAC and from the preamp to amp, RCA King Cobras from my phono pre to the preamp (Mogami Neglex from my turntable to the phono pre), a VDM5 silver sp/dif from my streamer and a VDM3 from my CD player. Nothing fancy, just things that seem to work well in my rig, and most all bought on the used market. I also use a cheap solid core AQ IC to my second amp which is a rarely used outdoor speaker driver. All of these cables are beautifully built and finished...but it's bungees...all bungees. I think generally AQ makes well executed stuff, but haven't used any of their newer things.

I could build my own solid core cables, but I might have trouble cramming them into bungee cords so I let AQ do that for me.

Try hooking your cables up backwards...all hell breaks loose, the cat explodes, and music becomes an unlistenable heap of cacophony rendering the listener on the floor curled into the fetal position wimpering, "stop, please stop."
