Now that you have a lot of peoples favorites or suggestions ( I gave suggestions because my favorites would not necessarily be your favorites ) you have to now consider pressings . So here are a few thoughts from my experiences . For rock I like Japanese and German pressing in general , the English/Great British ones can be good if you find one without a lot ot background noise , Reprise is a good label So is London and Abbey Road . For classical I am limited in experience to Chicago Symphony Pressings , RCA Living Stereo , Decca/London ffrr and Mercury Presence , for Jazz Blue Note , for Folk Vanguard .
I like fidelity of the new re-releases at 45rpm as well as the double vinyl 33rpm releases ( like Dire Straits " Brothers in Arms " ) .
All of these are available within reason whereas the MOFI original and the new Ultra Disc are Ultra expensive , as are the Classic pressing ( great fidelity but so so quietness ) the same with Chesky .
While all this is just my opinion it is some to start thinking about .
