I am still undecided. I am currently using the Stax SR-404 with the SRM-1 MKII solid state amplifier and it sounds wonderful but my Rotel's internal DAC, though nice for the money I am sure, is not up to the task.
Routeman21: Would you describe the Empirical Audio modification as a worthwhile one? What characteristics are improved?
The SR-404 is known to have a bit of an emphasis on treble which I notice. But it is less of a problem to my ears when the source is improved (tried 24/48 DVD video through a Pioneer 51FD using 24bit/192kHz Wolfson DAC - smoother but the Rotel bettered it in PRAT). Also, the bass is incredible in its extension but it has less "impact" than I am wanting. Bass seems to significantly improve with better source as well. With these two things in mind it seems like the ECD-1 may give me improved bass and a slightly lessened treble which may lessen the headphones treble emphasis.
There seems to be varying opinions on the 24MXL. I get the impression that it is more dependent on system synergy.
