Man, I hate break-in! The USB port on the K-01 was unused until last night, as was the USB cable, as was the Shunyata MPC-12, as was the Venom HC power cord. I know it is just a matter of time, but I have no patience.
So right now it is just a bit "stiff" although it also seems just a bit bigger. I played the Yes album "Close to the Edge" through both Silenzio/USB and the CD tray of the K-01. Straight CD is currently slightly better, BUT the CD port and Filters have about 700 hours on them and the USB port only has two. Basically, it is way too early to tell.
By the way, we are talking subtle distinctions of greatness here. Raw and right out of the box the Silenzio sounds outstanding as a source.
