Woah! Very nice!
Although I admit to fondling myself in the darkest of night to the thought of the KX-R and its many-chambered magnificence I confess I am quite interested in Mr. Doshi's creation. Any details on tube compliment and topology? Is there an optional or not-pictured PSU? Is the rectification tube or tranistor based? Details are scarce on this rare production, looking forward to hearing more about its sound at the very least!
FWIW the KX-R is - from a purely mechanical standpoint - one of the most impressive bits of engineering I have seen in audio, ever. If the White Unicorn bests it in sonic prowess I am aghast at the possibility. Congrats and let us hear some impressions!
