Ancient music requires a certain state of mind personally, but when in that state, I find it hypnotic. The recording of Bingin Ordo Virtutum I usually stream is performed by Sequential on Deutsche Harmonia Mundi/Sony Music Entertainment 1998 from Qobuz. Great hall ambience retrieval, good timbre.
For samplers I usually stream any of the 2L Recordings such as Psallat Ecclesia, Fingergull, Yule, Exaudiam Eum. I am a fan of 2L Tecordings engineering. If you are not familiar, read on their multi mike recording technique. Any of their offerings are an audiophile sound quality dream. On orchestra, their philosophy is to Mike as the conductor hears the performance, so it’s a up front presentation which some in this forum do not prefer, but I love.
With exploring 20th century compositions do not leave out works Part, Cage, Adams, Schoenberg, and Glass. Part is interesting from a tonal and structural perspective with his tintinnabuli (bell-like) minimalist style. From a sound quality perspective, and with an eclectic choice of instruments, try streaming the 2L recording Borders.
Enjoy exploring.
