I had Jupiter originally, then went to Miflex and subsequently put the ODAM in place of the cheaper and larger Theta foil caps Don had placed directly on the board for purposes of a subwoofer output. ODAM are much smaller than Miflex/Jupiter for a given size, so easy to place a 2.2uF cap directly on the board and leave the large Miflex caps mounted on the wood chassis off-board.
Miflex were not quite as sweet sounding as the Jupiter, but sounded a bit cleaner/clearer, and a bit less exciting high frequencies. The Jupiter do have a magic to them, but I had some reliability issues with them. So, kind of a lateral move between Jupiter and Miflex in the Sachs, IMO, but with some different strengths and could easily see different folks preferring one or the other based on personal preferences.
ODAM are MUCH cleaner/clearer than the Miflex, but more neutral/transparent, and thus a bit thinner sounding, without that nice copper foil tone. But overall much more refined, IMO. Make the Miflex sound fuzzed over to a degree. Once I heard it, I couldn't really go back. I use the ODAM exclusively as my primary output now and choose to season my tone using tubes rather than caps. The subwoofer runs off the Miflex outputs, which the 1.5uF is adequate. Some day I might get around to a second set of ODAM for the subwoofer outputs, which would be a better fit for that purpose given its strengths.
