Unplug your gear for a week, then plug it back in. Thin sounding? Absolutely. Give it several hours, and magically your system sounds just like it did a week ago. I've done this when I've travelled for extended periods of time, and also noticed the same effect when inserting a "new" piece of gear in my system (shipping time is generally over a week). Even used items need time to settle in and perform as expected. This may not be the technical diatribe some would hope for to prove that break-in is necessary but it certainly is easy enough to try for yourself. Unplug everything, wait a week or so, plug it back in. Proof is in the pudding. Jeff
