I have one of the later (TOG) Cyrus Ones.
It has been “upgraded” before I got it, back in 2008 or so.
However whilst we’re all under lockdown, and as the front panel badly needed repainting anyway, I decided it could do with a look over, including having a proper look at the electrolytics. The onboard polarised caps were all Panasonic FCs and looked in good order, so I left them alone.
The original PSU caps (which I believe were rather nice slit foils) had been replaced at some point by Nippon Chem Con KMG ones. Since Cyrus spec’d slit foils, I decided to return it to spec.
The original NP electrolytics had also been replaced before I got it, by ones from SJE (Sang Jing Electronics).
I decided to replace the main PSU caps (with 10,000uf slit foils from DNM) and replace the NP electrolytics (with a mix of Nichicon Muse and Elna from HiFiCollective). I did think of replacing the lower value NP caps with Poly caps, but I would have been tight for space on the board, so stuck with NCs.
Results are spectacularly good. I’m delighted and would thoroughly recommend these components to anyone looking to keep their old Cyrus One running.
