Not for nothing but....if the Vault has USB out and you use that in place of coax that would let the Weiss do the clocking which would likely be nice a low cost improvement.
What happened to the Innous discussion
I really wanted to read the Innous discussion because I recently bought, and then returned, an Innous Zen. I had several people listen to it a/b with my Bluesound Vault and the difference was so minor that most couldn’t hear a difference. One person heard a small difference and thought the Zen had more "punch", but also thought it wasn’t as clear and revealing as the Bluesound Vault
