What's the use of it for you? The AK70 is a portable music player, so how does this relate to your amp and speakers? It seems best used as a portable headphone amp and DAC.
If you want something for your home system, wouldn't a streaming device that can access streaming services as well as your own library of music be better? I use Bluesound products for that, and leave my PC off. Only the network is live so I can stream Tidal or TuneIn.
Well.. to play hi res files being the purpose!
I had a Bluesound with an NAD and it was problematic. Never tracked down to BluOS of NAD and traded out. So not a Hegel H90 and it connects flawlessly via USB where is becomes a soundcard or Airplay network.
I'm about to purchase Audirvana that plays a wide variety of music files. Considering others as well. iTunes is a real disappointment on many levels so must do something else.
I'm wondering if the Mac gets in the way at all. Seems like some of the even portables may do a better job than iTunes.
Or will software improve my situation?
I'm not going to go crazy on this system more than I have! Pretty much THERE but want ability to play more file formats.
Thanks,
Tex Az
