This might be a question for @ted_b: I'd either forgotten or never realized that NativeDSD had begun selling titles from the Canadian indie jazz label Songlines, which released a couple dozen albums in the mid-aughts with very good "in-the-room" 5.0 mixes. (Some but not all of those discs are still in print and available from Songlines' own web store.) So far NativeDSD has 21 titles. Do you know, Ted, if they'll eventually get the entire catalog?
