I'm with Khaki8 on the point that the original vinyl is representative of fine musical reproduction and engineering.
It's shoddy repressing or digitization that has degraded the sound quality IMHO. Go back to the original mono vinyl and give credit were it is do, I think you’ll see what I mean.
I'll keep mine and please contact me on anyone looking to rid themselves of those old, dusty, nasty, (low)-Fi Rudy Van Gelder Blue Note Jazz Mono vinyls from 1953 to 1967 in EX+ shape. I will pay you fairly for them so you can go on your way and buy more CD's and wildly priced cables and equipment to try and make music sound better than this. Ha, ha, ha. Especially, anyone with a copy Of “See you at the Fair” by Ben Webster on Mono Impulse… in fact, write me about the Impulse pressings too!
Happy Listening!
