I considered this receiver but the power source is only 360W. In comparison, on SR5015, I think, is 650W, almost double the power. Is not this detail important in overall performance?\nAnyway I think is a great receiver. What about Yamaha RX-A2A? the specs are almost the same as RX-V6A (TSR-700). Why the price is higher? Is it better? In which way?\n\nThe A2A is more robust in build quality all the way around. Virtually identical feature set to the others though. Keep in mind that HDMI 2.1 features are not available in any Yamaha until a firmware update is released to activate them. There have been two firmware updates to fix bugs but neither of them activated HDMI 2.1 or Dolby Atmos Height Virtualization features.
