Do 45 rpm 12" LPs really sound better than 33 rpm?

Chakster, "Music Direct" offers Charles Mingus "Mingus Ah Um" as a 180g 45RPM 2 LP set; other than a different diameter, are we still talking about 45 RPM records?

I also have noticed a lot of DJ dance single mixes are 33 rpm. Maybe for better bass or so the DJ doesn't have work as hard. Just me thinking a slower turning record would be easier to produce a bass signal. Please don't knock me. I'm no engineering wit.

Chakster, all record players played both 45, and 33; the same 45 that was on the jukebox; it's just that jukeboxes produced state of the art sound while most record players were below "midfi"; have you ever seen a 1 box record player.

Since jukeboxes relate to another time that you and younger enthusiast can not relate to, I will refrain from mentioning them; will that make you comfortable?

But jukeboxes relate to 45's that sound better than 33 1/3 LP's, and I hope to find some in mint condition.

Yes, we’re

But this is a NEW trend to offer re-issues on double LPs recorded on 45s. First of all those records are re-issues, not the originals.

The original LP is on 33 1/3 rpm

I can’t remember any LPs from the golden era pressed that way and they are all fine, some of them are better than those modern 45 rpm re-issues on LPs.

What is definitelly better is a classic 12’inch singles with one track per side, from the golden era. From the fresh mastertape to the stamper, deep grooves. Those singles are fantastic in terms of fidelity on regular vinyl (not 180g).

When modern labels like Analogue Productions working on a re-issues it’s all about restoration, since the tapes are old, so they want to make the best possible to re-issue 40 years old music today. In this case they need all those vignin vinyl formula, 45 rpm pressing, 200g vinyl, half speed mastering etc. The price for their re-issues also very high.

P.S. I have thousands of rare original 45s and LPs, i don’t care about re-issues much, but i have some of those from Analogue Productions. Most of the modern re-issues on 7 inch 45s are crap comapred to the originals. 

I think it's not correct to say that 45 rpm is better, it depends on each particular record and the source (digital or analog master, cutting engineer etc). 

I have Eva Cassidy's Nightbird on 33 and 45 rpm.. I did a comparison with 4 of my friends some time back.. all of us agreed the 45 rpm had more details and a bit more dynamic.. However 1 of my friend said he preferred the 33 rpm version .. as he felt it sounds more natural.. So all things being equal... most will prefer the 45 version .. but there will be some who prefer the 33 rpm version.
