I haven’t tried lifting my cables for well on 25 years. When I did, I heard a small difference and thought nothing of it. After reading this thread with all the usual suspects and sides, I tried doing it again, using some Yoplait Oui glass jars.
All it took was 7 of them to lift my speaker cables off the carpet. All I needed to hear, to hear a difference, was about 10-20 seconds into a well known CD to hear the difference, and ended up listening to the whole thing. Cleaner, clearer, period. Removing the Oui jars brought back the veil I had prior to using the jars. More of a smearing, actually.
No cost. Simple to replicate. Trust your ears and leave the arguments to the know it alls.
All the best,
