For the record, if I don't listen to my SACD Standard for 2-weeks or so, when I do play it, it sounds like a different machine, much better sounding than I remembered it being, the first couple of Discs are like a new listening experience all over again.
Sonic memories are funny that way.
Krell has stated that "side-by-side comparisons yielded no noticable sonic differences" between old and new transports.
For me, if Krell can't hear it, it doesn't exist.
