Hi-fi

[Callan]

Why does my integrated amp (onkyo a9050) have a built in dac. if like i was told optical and coaxial dont carry hi res audio? Cos i got a blu ray (panasonic bdt130) to play hi res music. It will be connected like so. Blu ray to tv via hdmi then tv to amps dac via optical. Or blu ray strait to amps dac. Will these two ways work?

A DAC is a digital to analogue converter. It doesn't matter whether the digital signal comes in via optical, coaxial or HDMI and it doesn't matter what the format is, it has to be converted to analogue in order to drive your speakers.

Can this analoge signal be high resolution sound if the blu ray is playing a flac file or say a music blu ray
