Recent experience. I have a Linn Lp12 with Kore, Cirkus and an Ekos 1 with sticky dial issue. It sounds wonderful, in tune now for almost 2 years. I spend alot of time on setup. I was using the old vintage tonearm cable as the sound was excellent saw no reason to change.
While at my local dealer saw a trade in Revelation DIN cable at a decent price. Purchased it. I can only say change of cable made such a noticeable difference. i am a believer in cable effects and have several upgrade cables. But I wasnt expecting the magnitude of the difference the cable made.
Thats something you might want to try.
