Years ago I heard a spectacular system which was a gold plated turntable connected to a pair of 300B triode mono-bloc amps and some lovely speakers. It sounded magnificent. No, it really sounded spectacular, it just that the recording didn't sound like the mastering engineer intended it to. As far as sound, it had a lovely warm sound with plenty of harmonic distortion but it was not what the record was intended to sound like.
If I wanted to listen to a distorted recording, I could do it far cheaper. When I listen to a recording, I want to hear what the mixing engineer heard in the studio at final mixdown. The mastering engineer tries to take this and massage it so it sounds as close to that as possible on the systems we mere mortals use. Single ended, transformer coupled triodes are not those systems.
Gold plated cables, stickers designed to absorb negative energy and interconnects with electrically biased insulation don't help.
