I put my AudioDeske on the far side of an adjacent room and close the door. Really helps with the drying noise. The AD came out earlier than the KI. I might have bought the KI if it had been available for comparison. It wasn't, so I bought the AD. Since both are around $4K, I haven't had the great desire to spend another $4K for the KI. There is a cost for consumables in the AD, but they are pretty trivial compared to the capital cost of the device. I have probably cleaned about 5000 records, part of my ripping project and will clean about 2500 more before most of my cleaning is over. No mechanical problems, although I know there were problems in the earlier production runs of the AD. My sense from talking to other crazy vinylphiles is that the KI is probably slightly better, both the AD and KI are substantially better than the VPI (which I have had in one form or another since they were first introduced in the mid 80's) and both of them are a whole lot easier to use, "set it and forget it" than the VPI. One thing using the AD that I discovered is that there is a slight residue left after cleaning with my VPI, and the AD and probably the KI removes. Almost all of the records that I have cleaned and am currently cleaning have either been cleaned by my VPI already or are new. Relatively few (1-2%) are used records that I have bought in the past three or so years that I have had the AD.
