If the output is digital does the player make any difference to the so

I'm wondering whether if you had two media playing pieces of hardware outputting digital music would the quality of the device make any difference? For example say you had a cheap-to-mid range android phone or mp3 player playing a flac file and outputting over HDMI to a receiver, and a higher spec digital media player like say the Olive 06HD playing the same flac file output over HDMI to a receiver would you hear/should there theoretically even be any difference in audio quality?

Thanks

I think it's the same with all modern devices and all modern digital connections, coax, optical, hdmi. Receiving device does buffering and re-clocking the incoming signal, so jitter is practically non-existent.
