I have had the entire sequence of Exemplar players, 2900, 3910, 5910, and soon the Shanling sacd player. There was a further mod of the 3910 with the post-dac filter parts largely replaced. I did not have this unit but heard it. That would be what I would seek. I heard the moded Shanling cd player at CES and was very impressed. I found that Shanling made a sacd player in the same series and asked John to work his magic on one for me. I should have it by the end of July.
