Hi @rolandas_stripeikis, I have not compared Aries G1 series with Aries G2. I know there is lots of trickle down tech in Auralic, but just assume the G2.1 is better, and that is what I have been told.
Someone once said this to me (paraphrased): "You have a Lamborghini of a DAC and without a separate good streamer you are feeding it regular gas".
I think the Aries G1 would improve things, but I also think Tambaqui is so good it should have the Aries G2.1. Like me, I think several people are upgrading again to the Grimm MU1 to pair with the Tambaqui. That is why you see the Aries G2.1 available. I will likely list mine as well after the Grimm comes.
