This thread has confirmed to me that, yes, there are more expensive solutions out there yet not many can even articulate in 2 sentaces. WHY they would be superior to Bluesound assuming both solutions use the same DAC.
I believe I recommended in my prior post to read Darko’s review of the Innuos Zen Mk. 3 where he not only compares it directly to other streamers but also offers possible explanations as to what aspects of its design and build may contribute why the Zen sounds better. If you haven’t read it you may find it somewhat interesting.
