I'm considering mains that are 4ohms w/ sensitivity in the 95/91 (room/anechoic)range. Would the Denon 3803, Elite 55 or Yammie 2400 drive these guys well - they are not rated for 4 ohms. Would I need to add a pair of monoblocks to these AVRs for the mains if I liked the other features they have? Or at that extra price point (AVR + blocks) would I still get better/cleaner power and enough features with the Outlaw 950/7100 or the Rotel products? I can't go above aprox $1600 for any of these options. What do you think?
