Try Accoustic Sounds at accousticsounds.com. The selection is large, including some superb recordings. The site can be a little slow to navigate in searching the selections, but it is the best I have found. The service has been very good, either by online or by phone. Also Red Rose Music has Marc Levinson's own master tape SACDs and their sound is very good, though with some tape hiss at higher volumes. For me, that is not a factor. The selection, however, is very limited at this time and not all recordings, perhaps none, will be to your liking. There are plans to release more from his collection of master tapes, but I do not know when. Good luck.
