What sounds best: Vinyl or CDs

Sorry about the repeats but my mind is not what it was!

Have had brain tumor!

I’ll chime in with my first impression when I read your speakers list. Twin def tech 800’s with ML ESL’s. IMO those subs are no where near fast enough to integrate well with electrostats. They are pretty decent for HT, and maybe even with some loose sounding box speakers, but they can sound very flabby and muddled when used with planars or electrostats. I can guess your ESL panel sounds pretty good with the NAD but even the ML bass section must be a bit behind and doesn’t integrate well with the subs either which just makes matters worse. Just an educated guess as when I was looking for a fast sub with lots of control to work with some Maggie’s a while back I tried the def tech and it just didn’t work at all in my room. With vinyl it just sounded sloppy as hell. Just an fyi.

I have a lot of vinyl that I've collected at thrift stores, garage sales, even record shop over the years. Most of my records cost about a dollar but some I've paid somewhat more. I listen to mostly classical and the cheap ones from thrift stores are often in pristine condition. I have a quite good analog setup: Michel Orbe TT, Graham 1.5 arm, Lyra titan cartridge retipped by Soundsmith, Lehman Decade phono preamp. My best records sound wonderful on my Electrostatic speakers. I have digital remasterings of some of the great recordings that sound good on my better than average but not world class CD player. However, the records sound better (Reiner, Scheherazade, Also Sprach Zarathustra, Bartok's Concerto for Orchestra). I have a lot of records that don't sound very good, not well recorded. Most of my CDs are less awful but still not as good as better records. Since I am a classical musician I listen to the great recordings but also listen to average recordings often because I'm into the music as much or more compared to the audiophile experience. 

When exactly will my vinyl, some I bought in the 60s, start to sound bad?
