Yes I Mostly use on board processing like 'ISF day' previously with SR7010 and Now '4k Enhanced' with SR 8015. It has a dedicated 8k input HDMI port, which is nearest to the HDMI output port. I'll compare pass through with others, Its been just 2 days with the AVR, let's see how it goes.Only a subtle improvement over the 7010 in SQ? And a significant upgrade in PQ?
SQ advantage is subtle but definite, over period of time it'll improve. SR7010 took nearly 2 months to sound optimum. Moreover I haven't connected External Amp to SR 8015 currently ( which I was with 7010) that's a confounding factor. Mostly because, I'm evaluating the new AVR for any Manfacturing defects. Hopefully I have answered your query.
