Boxer:
I assume that you have read my recent posts above. I stopped listening to records in 1992...after about 32 years of my life of that being the best media around. I do not have to spend thousands of dollars to buy
turntables (again) and music (again) that I already have on digital (mostly CD) in order to be fairly certain that vinyl is merely a current fashion.
Yes, I have auditioned vinyl on modern ultra-high end equipment. Sounds great...like well recorded records always did. Different than digital? You bet. Better than digital? To my ears, no. Convenience? No contest.
My main issue with vinyl, in addition to a long list of other inconveniences, is that you are stuck with the song selection and order pressed onto the record. And you have to flip the damn record. As in the old days, albums (with many exceptions) are typically two or three really good tracks and seven or eight of filler. Even if analog discs were scientifically capable of providing a better than digital playback, I could not tolerate being forced to listen to tracks I don't like to accommodate a out of date (albeit cool looking) media. Makes zero sense to me...and I've been around a while.
To your question....it has been 27 years since I've had a turntable. Audio memory is so perishable (a fact) it wouldn't matter what turntables I had back then...I'd be unable to compare that analog playback memory to present day digital playback of a well recorded CD or FLAC flie.
In recent memory, a number of digital "systems" failed though they were supposed to be better than CD's - DVD-Audio, Digital Tape, SACD and others. I fell for SACD. Was it better? Yes it was. But it failed because it wasn't better enough to buy all your music again. I dumped SACD after three years but I can still play my discs on my Oppo 105. Vinyl, I suspect will eventually fade away in the same fashion.
When the absolute sole "proof" of the superiority of records comes from vinyl aficionados, who tout that system as "sounding better," I'll take my ears, experience and science any day.
A sorta long-winded answer to your very polite question. My apologies.
