Auralic Vega G2 vs Aries G2

Looking for a streamer and a DAC...  I was looking at the Aries G2 and looking for a DAC to go with it.  Then I saw the Vega G2 which also has a streamer built in.  I don't need to stream files from a server or store content.  I just need to stream Tidal (maybe Spotify if in a pinch) - so the Vega G2 has all the streaming features I need.  There are articles that seem to claim that the sound quality of streaming content is better when using the Aries G2 + Vega G2 together (using their lightning connection) than what the Vega G2 alone will produce.  Is it me or is this marketing non-sense?  I can see using a separate Aries G2 if you need the extra features of a full fledged streamer but how can the SQ via an external connection be better than the SQ of connections that are made directly via internal circuits??  Another article mentioned that the CPU on the Vega is freed up to focus only on the DAC but again... seems like grasping at straws to sell that based on SQ rather than via feature differences.  Thoughts?
