Hi there. I use a 30+ year old Meridian CD player. I love it! But it certainly has its quirks. It does not play CD-Rs (which sometimes I burn from Bandcamp downloads) and occasionally it refuses to read some CDs (usually ones from small, boutique labels). That said, it does play about 95% of the CDs I throw at it. Anything it doesn’t play I rip and add to my Roon library or I play in my second system that has an Oppo player.
I purchased the Meridian from the original owner and it came with original box/paperwork, etc.. The seller gave me a one year guaranteed and if I had problems they were willing to take it back. I’ve had it for over two years now. I love the industrial design of the Meridian and think of it as a fun, unique piece on my rack. It does have its quirks, but I’m willing to put up with them since I have other ways of playing music. My point basically being, if you want vintage, then go for something you really want because you enjoy the brand, the history and influence of the component. Perhaps its legacy. And make sure you feel confident with with who you’re buying from. If you want trouble free and want to know it’s going to play everything, then consider new.
As for SQ, I have my Meridian player running coax into my BorderPatrol DAC SE and am very happy with the sound. No complaints — it equals my Stack Audio Link II Roon endpoint going into the same DAC.

[EDIT] Just read your comment about purchasing the Metronome AQWO 2+. Congrats and very nice! Disregard what I said above :)
