33rpm vs 45rpm - which is better

There are plenty of nice sounding modern jazz recordings too.  They are almost exclusively available in digital formats.  I don't think sound quality for jazz or classical has gotten worse since then, it just hasn't improved much despite all the supposed technical improvements.

                                             So Many variables!

     I own half-speed mastered, direct to discs and 45s, that all take me to to the event, as well as the same that don’t.

     Much depends on the recording techniques, who did the mix and master, quality of the vinyl, who built/adjusted the cutting lathes, amps, etc.

     Thus far: no vinyl tech I’ve personally heard, has outperformed the stuff that Sheffield Labs, Nautilus, Crystal Clear and MFSL produced, back in the late Seventies/early Eighties.

     Then too: Brubeck’s ’Take Five’ on Columbia, was my first Jazz album (conventional, bought around 1970) and it still sounds phenomenal.

     Crystal Clear’s ’San Francisco Limited’, D to D, 45 RPM album, is one of my favorites for evaluating a system’s sound.    White vinyl and (funny with that title) really good New Orleans Jazz.

12 inch 45's are King. I have this and it's my go to demo. You can watch the stylus and cantilever move....like a bee in a bee hive.

Never dived into the 45 vs 33 question - but I always found 78's were the best compared to a 33 of the same song. I assumed this was because faster speed = longer groove = the ability for more information to be captured in the cut. Applying that logic to your question, 45's ought to have the edge.

@aewarren Agree on the orange disc. Bought a Soft Machine Vol 1 to replace my 30 year old copy - amazing packaging compared to my original - working dial and all. Then, I pull out the record to see colored vinyl. Somebody need to tell them to stop doing this - just stop.

@zazouswing Actually I started a discussion on colored vinyl a couple of weeks ago (check it out) and was amazed at the number of respondents who actually like the colored and clear vinyl records. To each his own, I guess I’m a dinosaur.
