The ML 39 uses a cdm12 industrial transport. The wadia uses the pioneer 1343 stable platter—same as the theta miles. I googled both and there are replacements out there, but I don’t think the parts are made anymore. Cost for these replacements appear to be consistent around $250-300. Since the preamp I got didn’t work out, I think I’m rushing on just resolving the problem by just going with a cdp with good volume control. Cd is my reference, but I still stream via irDAC and ipad to discover new music. There is a mcintosh ma6450 local to me I may check out and see how it sounds with the revels. If it gels, I’ll likely sell the proceed and then likely checkout new players or go with a newer transport.
