Got mine finally up and running using Marantz 6011 bought as experiment for G68.

Using with 3x5500s, 6 DSP33s, SW1600 and a SW5500 in 7.2.2.

Quite impressed after running Audyssey setup. Watched Passengers Atmos from Sky Q and Mockingjay Part 2 Atmos. Scene of execution at the end really impressive. Will try out a 7.2.4 setup next weekend with some 18bit 5000s (driven by 565) releasing DSP33 for rear height.

Will look at upgrading the Marantz in coming months probably to XLR output processor like Arcam AV860 or Marantz 8805. Would like one of the digital output tees like Storm or Trinnov but they need to introduce a sub £10k model for me. Quite surprised how good a £700 (discounted) bought AVR used as processor is though!
