maxflinn:am i right in saying then , that if one is using a bluray player for cds , over hdmi to an av receiver , that the "dac" in the bluray player is doing the converting , and not the dac in the amp ??
No: the signal over HDMI is digital, and the digital-to-analogue conversion in the amp is doing the work.
ah , that does make sense , any data transported over hdmi can only be digital then ? so when watching a bluray with say , dts master audio , how do i know whats doing the decoding , the sony or the yamaha ? im assuming the yamaha would be better doing this ?
