It’s not marketing nonsense because the manufacturer is on record on several forums stating that if you just want to stream Tidal the Vega G2 will suffice. Aries might add a slight bit more to streaming in addition to being a server.
As a Vega G2 owner for the last few months I can tell you that the sound quality of Tidal streaming directly from router is nothing short of spectacular. Beats any dac/transporter/renderer/server combo I have ever heard at home. Don’t need expensive cables, outboard power supplies, or USB filter/fixer. Volume control is great too. My system now consists off: router-> Vega G2-> amp->speakers
