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?

They do but I am not sure it is by the margin many think.  For me, I would rather sit back and listen to the full side instead of getting up to flip the side or put another record on every 10 minutes or so.
What is your question? The physics dictates that 45 rpm is superior, but you won’t always hear the difference if the source material is flawed. However 33 should not sound BETTER than 45. Possibly your turntable is having issues at 45 rpm. The auto engine analogy doesn’t help.
"NUANCES" sound better at 45;  it boils down to how intense a listener you are;  that's my take but I'm looking forward to other responses.
Classic Records have some single with 33 and 45 rpm cut on the same LP.. You can easily compare them both.. Like this Look of Love Single

I should disclose first that making a 12" at 45 rpm takes the LP feature away, which I don't care for.  More importantly, all else equal the faster the speed the more noise will be generated.  This can be significant for the stylus tracing the record groove.  Everything is a trade off.  Some of the gains are offset by the loss due to the inferior signal to noise ratio.  The extra vinyl muffin costs pennies and it is actually easier to master at the higher speed so it takes less studio time in most cases.  Time is money.  On balance it is a marketing ploy to pry more money out of the consumer for a more profitable product.  Sometimes 45 rpm records sound better, but not always.
