Amazon Launches Lossless "Hi-rez" HD Music Service

Mahler.
I remember you seemed to have had a lot of issues on your Bluos updates whereas I am in MoFi camp where I never suffered at all during updates.

However yes the Vault is long gone.

I have had ZERO Update issues with the two BLUOS Node 2i that are used in two separate systems.

Cheers......

My hope is that Roon partners with Amazon's Hi-Res group and offers it, if they do, I'll try it out...and probably terminate my Qobuz and Tidal subscriptions.

most of my Bluesound issues related to not all 4 of my units in the house successfully updating in sync.  The Bluesound updates were frequent and occasionally one player would get hung up.  That somehow led to all of the players failing, and would require calls to Bluesound.  My main system is my 2 channel system and the Vault2 there has been superseded by a Bryston BDA-3, but I kept the Vault2 in.  My other systems have Node2 players.  Life has been quiet in my Bluesound Universe by refusing to do updates, and it isn’t worth disturbing the peace to add Amazon.  I’m pretty happy with Qobuz.

Just realized that Chromecast audio doesn't send out Ultra HD via toslink (downgrades to HD or Standard).
This really grinds my gears...grrrr...
