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


Increasingly, one can buy 12-inch 45 rpm LPs. Theoretically, they provide a wider dynamic and frequency range, but I come across a strange effect... Yes, the bass strings seem to be tightened stronger, but in general ... Imagine you have two cars with a power of 250 hp, but one is equipped with an honest atmospheric V6 or V8, and the second has 2 liters turbo. 

Tell me, is it just my impression? Or maybe I need to change the cartridge or settings (for example, impedance) of the phono preamp?

More dynamics. Better by a large margin than LP. When I was heavily into vinyl I would only buy Japanese pressing and also any 12” 45 rpm versions or singles of my favourite hits. Living in Canada our vinyl quality was garbage. Imports is what most serious Canadian collectors bought. Germans may have fared better with local quality but Canadians got garbage quality vinyl.

There has been a lot of discussion about the MM reissues (either in 2x45rpm or 33.3rpm) versus the RVG originals. The issue will never be resolved, because they are sonically so far removed it's almost like comparing different recordings.

I always seem to get the impression that the MM's are more faithful to what's actually on the master tape, although I obviously never heard or will ever hear what's on those tapes. The MM's sound incredibly clean and free of distortion, while still having realistic dynamic punch. This is often how people describe master tape sound and each time I hear one I think it can't get any better.

But all that sanity is thrown out the window the moment the needle hits an original. Yes, these records were cut 'hot'. They're very loud and can be a bit uncivilized, sometimes harsh and even shouty. I can imagine this being too much for a high efficiency horn based system. But in terms of sheer exitement nothing really compares.

Oh, and top grade NM copies of the originals are not really noisier than modern vinyl. But finding such copies has become almost impossible, unless you're prepared to pay a small fortune. Actually, in my experience even 'well used' copies can still sound quite good, try that with 'modern' vinyl. Thanks to the loud cut the music will easily overpower any surface noise.



Chakster, do you mean to tell me that one 45 RPM record sounds different from another? That the difference in the diameter of the record makes a difference in the sound?

I think you are uncomfortable with what I'm talking about because you don't know what I'm talking about; they evidently didn't have lounges with state of the art jukeboxes where you are. How about "Malt Shops", did they have them? Now you're going to tell me that the sound of one 45 RPM record is drastically different from another 45 RPM record. Is one 33 1/3 drastically different from another if the records are of a different diameter?

It all boils down to the fact that you can not relate to what I'm talking about, so you think that others don't know what I'm talking about, but I believe they do and can relate to what I'm talking about, and understand the relevance.

Chakster this is the same "Sidewinder" that was on the 33 1/3 LP that was on the juke box. I could go on all day long with 45's that were on LP's as well as 45's on jukeboxes; what more do you want?

Ok from my research on the net 12"45 rpm records produce better highs and midrange. 12" 33 rpm records have better has response. I just jumped in and didn't read all the posts like I always do.
