Do cables really matter?Yes. They transmit the signal.
What are your thoughts.
Do you really want to know the answer? Your original post is somehow, in advance, dismissive of those who say the cables don't matter.
I find them, to some irrational level, increasing the pleasure of overall experience without changing the sound. Of course, provided that they are not cracked with loose contacts, or something like that.
My hearing is fine. My experience with multi-thousand-Dollar cables very limited.
