Auralic Vega G2.1 vs Lumin T3

Some questions as I'm evaluating a similar upgrade.

1. Is Vega only the DAC? Their confusing writeups on the website suggest Vega is a "streaming DAC". Doesn't Vega have an inbuilt streamer.. why get Aries on top? 

2. How have you "optimized the signal to the Aries"? With their power supplies? Sirius seems to be discontinued.. did you mean their Leo master clock?

3. Does Vega come with a remote? Important to me, as I want to connect both my TV and my Streamer with the DAC, and want easy ability. 

Thankyou @mgrif104 - very helpful, appreciate the patient and insightful notes. I'll demo the following setups 

1. Auralic Vega G3 alone (+ maybe LPS)
2. Auralic Aries G2.2 + LPS + Mola Mola Tambaqui 
3. Auralic Aries G2.2 + LPS + Vega G2.2 
4. Grimm MU2 alone 

Thank you. For the Aries / Vega combo.. what cables would you recommend?
