your postulate of asymptotical closing of the gap between vinyl and digital seems counterfactual: vinyl suffers from distortions simply not present in digital, e.g. tracking angle on conventional tone arms, warp and flutter depending on pressing quality, imperfect reconstruction of the RIAA curve in the analogue domain, tonearm, step-up and analogue cable distortions to name but a few. Admittedly harmonic distortions on vinyl are euphonic and therefore often preferred to the ‘cold glare’ of digital, that however doesn’t mean they aren’t distortions. I fully agree with @lalitk that digital needs lots of work and am well aware of your state of the art setup on both vinyl and digital.
i guess i’m cursed with this whole listening thing. i find the best possible digital and vinyl sources, develop my system to tell me the truth without compromise, then listen to both every day. and draw my conclusions.
all the rest is noise, obfuscation, and rhetoric.
you are welcome to join me anytime for listening and point out where i’m wrong. seems obvious.
certainly there are good, better, best recordings too. so each digital and vinyl event has variables. the media is 'more' variable with vinyl.
