Update after about 80 hours (+ previous break in from the last time I used them) -- I'm pretty impressed with the Mogami in my system. It is at the critical point between source (CDP) and preamp.
First, I've never heard such precise imaging ever from my stereo. Vocals are reach-out-and-touch in front of me, as are other instruments/cues. Soundstaging also is very dimensional. Bass and mids have filled out nicely. And they have tamed some glary nasties I've been dealing with, one of the most appreciated improvements. All of the above equates to a much more musically involving experience. So for right now at least, they are staying put and I'm really enjoying them!
