I recently acquired one of these, and will be searching the archives for answers to questions I haven't come up with yet
Pristine example from an owner who upgraded, one of the last MX151s to come off the line. I have been tuned in as to the detail associated with setting it up, so I'm spending some time (while I look for a new amp and speaker builds to play themselves out) perusing these forums in an effort to head off difficulties at the pass, as it were.
First new pre-pro in 18 years knowing Mac and my Klipsch Cornwall cabinets get along well together, so it seems a natural match. with any luck it will have a long stay here, too. I tend to settle in with gear if I like it/it works well, not much of a "flipper" and tend to stay with what works - even if for longer than advised. I'm replacing a Krell HTS - the original one, which I got a generation or two later as a closeout, so that reinforces the point.....
