Pro-shot DVD?

This may seem silly, but I had some questions regarding the Hadestown pro-shot DVD release.

So I see it's available to preorder through Amazon, but I was confused as to how I saw a posts here a few weeks ago of people saying the sound quality of the DVD was poor. I thought it wasn't available to own until October?

Additionally, to piggyback off of that, do you think I should wait to preorder it if the sound quality / audio is not great (last I heard they were working on fixing it)? I really want to own the pro-shot DVD -- should I wait? Do we think the DVD will sell out? Am I being anxious for no reason?
