well, i'm back, and measurably better equipped with a topping e70, which recorded a better sinad than the khadas tone 1 it replaced
and at risk of chastisement, sounds better
anyway, having just read the comments of the cable guy, i wonder if i am doing my current chain a disservice by having to swap the hefty pair of canare 4n rca connectors (too short for the situation) for a pair of rca's on a thinner set of wires terminating in a 3.5mm stereo plug?
from prior advice here, i expect i should just shut up and enjoy the music, but is there any likely benefit in having separate shielded left and right connections versus the Y connection described?
no, this isn't trolling, but my profound lack of understanding of the differences in routing of those 2 options once they get to an amplifier (in this case a nad d2030), and indeed, intertwined or physically separate en route
thanks for any learned comment, or please bounce the question to a more relevant thread if that's appropriate
