the 390S shares quite a lot with the 39. It is my understanding that the is field upgradeable, and the only change is replacement of the analog board. Check with your dealer, but this is what my dealer has told me. Same DACS.
ML 390S vs dCS Verdi/Purcell/Elgar Plus
Currently owing a ML No 39 as digital source, I am planning to upgrade my system to either the new ML No 390S or (very expensive...) a dCS Verdi/Purcell/Elgar Plus combination. I have no heard the No 390S yet, but people have told me this is an absolute fantastic processor which has little in common with the No 39 and is even near SACD sound (?!). What interests me is whether the quality difference justifies the extreme price difference between these components. Any other recommendations welcome on upgrading my source.
