My own experience for what its worth, is that the fun is in listening to the break in process. I appreciate som burn in by the manufacturer since it eliminates DOA units and mistakes that don't perform.
When I start listening, I capture my initial impressions, especially any differences I hear from when I demoed it. Problem is usually that what I heard the unit with was different from what Inhave in the system that its been dropped into. All kinds of issues of system synergy can become apparent.
The microZOTL seems to have amazing clarity and dynamics in my system (Zu/DL-103 cartridge, VPI Prime, Parks Audio Budgie SUP, Bottlehead Eros phono preamp, microZOTL as preamp, First Watt F3, Zu Omens). I've already repositioned the speakers to rebalance treble and bass balance.
I brought up break in just because I hear a bit more closed in sound and a different tonal balance than what I heard at the Capital Audio Fest.
So I'm just spinning records I know well and listen for changes. It'll be weeks to accumlate the 60 or so hours it might take. For me, part of the fun.
By the way, I loved those Quicksilvers back in the day.
