I know the Vault is not an option but just in case I wanted to share that I have two Vaults over 5 years and both failed, the first was replaced the second not. It failed during an upgrade, but since out of warranty all they offered was a reconditioned older unit at half the retail.
I wonder how I can still have hifi equipment from the 1980s that works fine and a reputable manufacturer such as Bluesound seems to be OK with some of their equipment failing within 3 years.
