I know you're very familiar with totaldac products so I'm very much looking forward to your review of the D1-seven.

I know it's off-topic, but I seem to remember that you had the Schiit Yggdrasil in the queue for review. Is that still going to happen? Would like to know what you think of it.

The review Yggy unit I received sounded broken so I returned it. The long story short is Schiit never sent it, or a replacement, back. I've sent a number of emails over the years but they've either gone unanswered or have been ineffective at getting a reviewable unit here.

I've stopped trying.

Don’t feel too bad, they don’t respond to potential customers, either. I gave up too.
