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.
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?
