Sorry I have the Super 8XRS, but have had them for about 5 months and they started singing in 3-4 days. One tip, the thicker the gauge on your speaker wires, you will get a bigger and deeper bass especially with the H2 with its 1watt output. No need for audiophile cables just any thick copper
With my buddy's Compact Alnico Monitors, they really didn't settle in and really sing until after 150 hours (I had them in a casita facing each other, out of phase, playing continuously). It was actually interesting to hear them go through different phases of break in (better then worse then better in a different way, etc) When fully broken in, the sound field (esp. depth) really is incredible, esp. in near field.
