Well, I ditched those Mooks. You know the ones.
And one or two tweaks I've tried recently sounded v nice initially but became apparent they were euphonically coloured, e.g. IsoAcoustics Gaias.
Some were really useful in my old room but only marginal here, and JUST deserve to stay in ie Entreq grounding.
Some are great on some gear and marginal on others ie SR Black fuses.
Others are just slam dunk crazy good and my system just loses magic without them ie Stacore, Sablon cables, Westwick balanced power w Oyaides dedicated lines/Furutech sockets, RevOPods under my Zus.
And my newest discovery, a "simple" Tubulus Argentus DB-25 cable that connects my pre to its psu, just strips out so much noise that microdynsmics and ambient detail brought to the fore.
Every so often I progressively strip these out (only my Stacore stays put 100%, it's part of my tt now), and the result is a shrunken, harder, hazier, greyer sound.
