I've narrowed my choices to these, which are in my $479-$599 range; Denon AVR1910 $549 or AVR790 $499 Onkyo TX-SR607 $599 or TX-SR606 $599 Yamaha RX-V565 $479 However, after researching on this forum. I've found I can step up to the next model by buying factory refurbished with a 1 year warranty; Onkyo TX-SR706 $499 Marantz SR5003 $549 I have four(LF,LR,RF,RR) Klipsch XB-10 speakers(50W continuous,200W peak) and an Klipsch XL-23 center speaker(70W continuous, 275W peak). Also a Martin-Logan Dynamo(10", 200W continuous) and a Mitsubishi 65" DLP TV. I'll watch 90% movies and 10% TV. Do you guys recommend a new lesser model or a refurbished higher model for the system I have? Out of the choices listed, what are the pros and cons for the different models and brands for the speakers I have? And finally I'm wondering what guage wire to use. The longest length to run is 37ft(RR), the other four runs are shorter. Looks like 14 guage would be good for sure, but what about 16 guage?
