Audio quality WD live TV (gen 2) vs (Gen3)

I am a happy user of 2 wd live tv (gen 2) with the usual issues that are published in this forum (network shares, etc).

 I use one of them as an audio server with a dedicated HD ; and it feeds an external DAC/audio equipment. Does Gen 3 has any improvement in digital audio signal quality over the previous gen2? is the new processor used in Gen3 a better option only for digital audio signal? which other wd product has the best digital audio signal? Thank you in advance.

The Gen3 has a better processor, but I don’t know if you will notice any difference in audio quality.
