My experience (perceived experience, to clarify) with my NFB-3 is that it sounded pretty much the same the first time I powered it on last spring as it has each subsequent time since. I am "a believer" in headphone and loudspeaker break-in because they are electromechanical transducers, and believe in electronics break-in to a lesser degree. Tube gear obviously changes sonic character over the lifetime of the component tubes, and capacitors need a chance to "form" the first time current is applied to them, but the Audio-gd equipment is advertised to have 100 hours of burn-in time on the bench in China prior to shipment, so solid-state components (no tube gear in Kingwa's design portfoilio) should have settled in to their electronic characterstics before being sent to the buyer. I know my ears gradually acclimate themselves to anything new in my component chain, but once the NFB-3 replaced the Maverick Audio D1 DAC/preamp that preceded it, I noticed no further change other than the big boost in clarity, detail (particularly at low frequencies) and the lower noise floor that it immediately provided. Adding a KICAS headphone amp and then an Audio-gd Digital Interface each made for another major improvement in SQ, but the improvement I heard when I powered each one on for the first time is pretty much the way it still sounds today.
Wish I could say the same for my ears. The system sounded soooooo good that I listened a little too long at what in retrospect was probably a little too loud a level (though it did not seem that way at the time) and I developed some pretty persistent tinnitus from my euphonic-sounding HD650s and had to back off to low-volume speaker-only listening for awhile. Even though the ringing was still persistent, not having transducers compressing the air in direct proximity to my ears made it seem a little more tolerable. You'd think I'd know better since I wrote the entry for "decibel" in the Head-Fi Glossary of Terms wiki:

Anyway, don't want to start a religous war over compnent break-in; it can be as divisive a topic as cables.
And it 'completely changed' in 5 hours ?
