I have the Retro City Rampage soundtrack on vinyl, and...well...it sounds the same as the version I have on CD and the FLAC version they provided. Considering just about every game soundtrack is produced digitally these days, remastered or not, pressing it to vinyl just isn't the same as people want it to be. It's paying top dollar for a completely silly product. I see remastered LPs selling in electronics stores today...which is the remastered CD audio pressed to vinyl. It's just plain silly.
I don't really wanna go down that road in this thread (we already talk about it in the vinyl thread) because it's a whole can of worms. There's a lot of wrong assumptions though, regarding vinyls. Vinyl doesn't automatically mean better sound quality than CD. Also, your setup matters (a $15 preamp versus a several thousand dollar receiver). If the CD isn't compressed to shit, and the vinyl version sounds just as good, that's NOT a bad thing. There's other benefits of vinyl over CDs, aside from a possible sound quality difference, from a collectors standpoint. Personally, I really enjoy looking at artwork, and that's always better on vinyl over CD.
But I understand the concern completely. I grilled this guy about quality already. With another label that he has, he explained to me that he's doing it right (getting original source where possible and properly mastering it). I'll have to talk to him more about retro game OSTs though, since there isn't gonna be master tapes. I'm curious myself what the process will be. I'll report back when I have more info on that. What I can say now though is that he told me he's got an audio engineer that is apparently very good.
