Just looking to upgrade my AVR to one of these three....  
leaning towards the 7013 as the deal on a brand new one is amazing.  But something about a “simple British amp” has me interested.   The Yamaha has always been my go to brand .... 
with only being it with a 5.1.2 setup — a pair of Klipsche rp8000f, 504c, 402s, and 500sa atmospheric speakers.
