The only other thing I have to suggest within my experience is to replace the CMOS battery, a 2032 from memory.
I set my dad up with an MD600 and a couple of MS200s - which he loves, so I have a bit more experience of MD600’s than my single unit might suggest. I have a spare one in the attic in case of a failure. A few years back the one my dad has started failing to boot up so we replaced his CMOS battery and I did my two units as a follow up “preventative maintenance”. He had a hard drive fail recently, he had smaller drives fitted to his MD600, effectively his CDs and a curated selection of my collection. I thought I’d made a separate back up of his MD600, maybe I did and it’s on one of the old HDs that’s in my spares box! But I couldn’t find it so we bought a new pair of 4TB drives and he now has a clone of my MD600 with the full spectrum of music. Quite what he thinks of the wilder and heavier choices in there he hasn’t said….
I’ve replaced power supplies on a few bits of Meridian kit but never had to do my MD600 which has probably been powered up, pretty continuously, since I got it about 12 years ago having very rapidly outgrown the MC200 I had before that. Do you remember if it’s the same as in the G series units, a quick look at the
Picture on Duncan’s website looks similar but perhaps not the same one.
Good luck, I think if you have a decent collection of your own music this is a fabulous system. If I didn’t have 1000’s of CDs I might be more interested in streaming as a starting point but at the moment I’d be paying to listen to music I already own, yes I know all the good things about HD formats and the metadata etc that Roon throws at you to follow links to other artists etc…
