Step up from Bluesound Vault 2, next move?

I have owned a Bluesound Vault 2 for nearly 2 years. I bought primarily to rip my CD collection to be all in one place.
However over the last couple years my listening has changed and I mostly stream Tidal through the Vault or listen to vinyl.
So I already have all my CD ripped and not likely to add many more in all honesty.

The Vault is likely not the last word in streaming quality I realise.

So suggestions based on experience please.
If I am going to update to a newer server I may as well make it a server DAC so I can replace both the Vault and the Brooklyn in one move.

Obviously the sq needs outperform the Vault fed into the Brooklyn.

I have backed up all my CD collection from the Vault to a separate 2tb USB drive so will be able to access those as a local drive ( I hope).

What is the most logical next move?
