Vintage DACs. Do they hold up over time?


I'm talking about Dacs from the 90s that were well regarded like the Timbre tt-1, Sonic Frontiers SFD2-MkII, Threshold DAC 2,
Wadia 25, Altis Reference, Levinson 36, Meridian 566-20, EAD9000,
Kora Hermes tube dac etc.

You surely forget the JADIS JS1 MK1 (tubes unit in 2 pieces), FORSELL DAC REFERENCE and also on a budget CALIFORNIA AUDIO LAB ALPHA. I am pretty sure they are still in the game despite they are nearly vintage ...
I'm still using my Muse Model 2. I do wonder what it would take to better it, other than a better Muse.
