There's a few labels that are similar in that respect. Hooj probably gets my vote, if not solely for the music then for the artwork on each record.

Not quite as extensive, but arguably a better ratio of classics to total records released.
I agree, plus Positiva rarely are the first issues of tracks, they are usually re-issues of tracks that have become more commercially viable
