Last week , I changed a PS Audio perfectwave AC5 Power cable for a Puritan Ultimate on my LuminX1 . Very very pleased with the result.
New power cable for streamer.
I did not think it possible, but when I replaced the stock cable on my Cambridge CXN V2 streamer with a new Audioquest power cable the difference was startling. I didn’t imagine a change of cable on a streamer could make any difference at all, but I took a chance.
