i dont see how, emergingsoul. i see what you describe and exactly what you name all the time. if ur looking to spend money theres no shortage of dealers lookin to help, many specializing in the audio you describe. some of em, the rare times they carry less expensive stuf, overprice it according so it wont feel out of place! haha. skyfi audio keeps comin to mind.
aside from dealers, the usual places continue to provide what you ask.
"I have never been able to find used cables that are what I’m looking for from transparent, cardas, ect, or other.."
that makes no sense at all. i see that stuff all the time. i dont know what tiers it occupies, but here are the brands u ask for
