My Brooks Berdan custom modified SME IV tonearm. Both fortunately and unfortunately, he fitted it with the thinnest silver Cardas wiring, shot closed foam in the armtube for elimination of resonance and epoxied both ends of the tonearm and RCA box so it may die one day.
Also, I don’t anticipate upgrading my speakers unless I become wealthy (Von Schweikert VR9....to an Ultra 9 or 7).
Also, I don’t anticipate upgrading my amps, Westminster Labs REI or CD transport Jays Audio CDt3 Mk3.
Everything else is open to change without any date or really desire at this time. Dumped most of the tweaks as unnecessary with high end equipment.
