Here is another point of view. I am very used to the Blue Note sound , beeing
collector of original pressings , mono and stereo. Reading about the rave around
those 45 RPM reissues, I bought Horace Parlan "Speakin my piece" and compared with the mono deep groove and the stereo New York USA reissue.
The 45 RPM sounds quiet, detailled, and respects all the frequencies, but the soundstadge is thinner, the feeling is dry and cold,and tiredly pronounced, like digital. The mono sounds full bodied, engaging ,warm ,huge soundstage, less detailed, but you want to listen for more lenghtly periods. The stereo is also warm , more consticted soundstage but also appealing. Having the 3 copies , if I have to choose I'd listen to the originals rather than music matters reissues. But I am lucky to have the choice, the prices are so high now. The Japanese King are less expensive and are very quiet and similar to the New York issues sonicaly.
This is for the sound. The vinyl work is of a lesser quality than the originals or japanese: slight warping, label not strictly in the middle,...
Art work is nice, nice pictures inner cover, but could add more info like mosaic did. For me 45 RPM is maybe a theoretical advance but in reality it is not better than 33 RPM . Plus the hassle to turn record every 10 min.
This is my observation. I prefer 33 rpm even cheap Blue note reissues.Sonicaly and on practical point of view.
