I've only had 2 issues with Esoteric (not noisy transport, 1 video board and 1 DSD module) going back 5 years. I can tell you they went out of their way and then some to remedy my issues. I own a P-03U/D-03 still since late 2006 and have no issue with noisy transport. I've also heard no feedback of the kind with the K-03, K-01 or later P units. You should also audition the K-01...
