They are stacked, not side by side. Thanks for all your help. Bit of a mystery--I have a Simaudio W5-LE that became superhot in my sytem after a listening session--Came home after lunch (I leave the amp on all the time) and smelled hot plastic--needed oven Mitts to remove the amp from the system--sent in for repair, passes all tests just fine. I had the amp in my system for 3 weeks (purchased used here on audiogon).
I love the sound of the amp (or lack of any particular sound) so I think I will go back to my XLO Ultra 6 cables for a while just in case.
