The Vault is just the Node with added Functionality—it rips CDs and has a 2TB storage. Ripping couldn’t be easier-after adjusting the settings in goes the CD and a few minutes later out it comes. It isn’t a perfect ripper but as a ripper it bests my Bryston BOT, which I now just use as a CD transport. I actually use my Vault2 as a streamer only, as I had backed up the stored files to a NAS, and I had a Node2 in another system that died. And that is another issue with Bluesound—scan enough threads here and you will find many owners whose units have given up the ghost after a couple of years.
My Node2 died about a week after warranty expired. Most CD transports will go for a decade at least until the laser craps out.
I don’t know why you think the Node beats CD transports. We all hear differently. Rereading your original post, I am unsure where your files come from. Are you streaming from Tidal or another source? There may be other variables here
