Love getting new equipment, hate the break-in

My experience is a little different. I find that speakers and cartridges-things with moving parts-change a bit with time. I haven't noticed a big change with electronics, and I suspect that at least some of the change is my brain acclimating itself to the sound of a new component, which is a real thing. This is one of those interesting discussions, but not worth of any unpleasantness-we are all different. One of the most foolish things i can imagine in this hobby is trying to tell someone else what they hear.

@tooblue - yes, I forgot that, and I just got a new Hana Umami Red cart a couple of months ago, and it's still improving! Nice thing is that right out of the box it sounded better than my previous cart. 

@ghdprentice  "went through the classic flip flop around 120 hours... very common with amps and preamps, where it sounds terrible one session and glorious the next a few times. Then kind of stabilized and slowly gets better." It reminds me when I was breaking in Pathos InPol integrated and after about 200hrs wanted to present its glorious sound to my wife. Well, it sounded awful, my wife looked me with WTF and I was dumbfounded. It took easily another 200hrs to shine and stabilize.

The OP would hate CMS footers- large sonic up and downs during lengthy break-in

When I bought my new Pass Labs monos, I was told there would be a five-day break in period. Fired it up and it sounded terrible, miserable and just could not recognize instrument or voices. Every morning I’d wake up only to find the same sound. I started to wonder if it would get out of this foggy state. Groundhog Day every day.  On the 5th day while still in bed wondering if this miserable sound would still be there. Nope. Full glory. It all came together. The surprising part was it was not a day to day incremental improvement. It was the last 10-12 hours that it changed. Went from zero to 100 overnight.
