Sloaped I'm running a 100/150 combo only because of speaker upgrading from a small room into a larger room and that's what I ended up with. I wired mine in parallel for a 3.43 ohm load and have never had any issues whatsoever with our older 75wpc H/K AVR635 pulling that load in almost five years of daily use, although I am using a Rotel RB1080 pre-outed from the 635 for the mains (80s).
We're upgrading to a front projection system sometime this spring and then I'll probably get another 150 to match the current 150 but in the meantime the 100/150 combo is working perfectly fine and dandy.
