Raspberry Pi to A/V Receiver

[arges86]

I got a Raspberry Pi for Christmas and I decided to use it as a music streaming device.
I installed Pi MusicBox on it and I'm running audio to my Pioneer AV Receiver through an HDMI cable.

My question is,
will getting a DAC like HiFiBerry or a USB one like this one from Schiit make any difference in sound quality?
I've heard from some people that they will, but to me it seems that the receiver is doing all the signal processing, so an addon board would be superfluous.

Any thoughts would be appreciated.

only your "golden ears" will know the difference....

OK

That's what I assumed.
