I see you're limited on spacing. I faced the same dilemma, but mine had more to do with cable lengths. I purchased a desktop shelf from Poppin, it's the Series A. Super slick, functional and unobtrusive. May alleviate having to set your Pathos ontop of your Direct Stream and it's only $99. I've got no skin in the game with "Poppin", I just wanted a less expensive alternative to a rack system.
