Wrapping power cords and interconnects with copper foil.

Ok..not sure other people have done what I tried recently but I’ve found a night and day difference in sound quality after I wrapped my tube power amp power cord (rogue Zeus) and my cheap audio quest interconnect cables with copper foil. I even wrapped by phono cable coming out of my turntable to phono pre-amp. The detail retrieval and pin drop silence after doing this has made by jaw drop. Cost was $40 worth of foil wrap. What do you audiophiles think? Have I changed the sound signature in a negative way somehow?

If it works for you…..it works for you.   IMHO, a properly shielded cable will not benefit from additional shielding.

How’s it work for a hat?

You have discovered one reason why better cables matter. Proper shielding makes a big difference. I recently acquired a new to me power amplifier that only supports RCA. I tried several cables on hand, none expensive, one had hum, one was murky, the others okay. I plan to replace them with something commensurate with the rest of my cables. I would start with an investment in a good pair of interconnects.
