Purchased the 17cubed last October (S/N 215) and ran it about 8 - 10 hours a day through mid-December. I'd guess it settled in after about 280 hours use.
Changed to a BP-26 I had bought for my son, and ran it from mid-December through late January while assembling his 2-channel system. Then back to the 17 cubed ever since.
Clear difference between the BP-26 and the BP17 cubed, especially in mezzo and soprano voices and choir articulation. Also, significantly less listening fatigue - - almost none. Sticking with the 17 cubed! (If finances permit, I might change out my 4BSST2 for a 4B cubed later this year.)
