” If anything the gold pins make the sound slightly warmer by a fraction of a percent, but it’s really splitting hairs.“
My findings also in the last ARC gear incumbent in my system REF 10 into REF 250SE altho the Electro Harmonix that I tried were Cryo’d as well as gold plated pins.
Were I to rate the variants with NOS DR’s as a 10 imho
DR’s - 10
Elecrto Harmonix Cryo Gold pin’s - 7.5
Current production Sovtek - 7
