I actually think that the vast majority of "breaking in" is just getting used to the incredible sound stage that these speakers offer. It truly is a foreign sound when one first hears it. A good analogy would be headphones. One can put on a pair of topnotch headphones, and listen to music that has a flat frequency response curve from 20-20,000. But some people don't like them and prefer speakers. Sam thing with OHMs, but as in headphones one needs to put in 100 hours of listening to see if this does it for you and for many it will- just look at all the earbuds that one sees.
Having said all the above, I admit to fiddling around with speaker placement, switch positions (I have 5000's), etc until I was happy. Now I'm at the point of, "if it ain't broke, don't f*** with it". As a confession, I switched out the WWII 6SN7's for the Black Treasures from Shuguang- the RCA's were too microphonic, but they did give voices a dreamy quality, like being transported back to the 40's.
