My friend who had a very complex, dedicated, music computer feeding a top model Lampizator DAC, recently dumped the computer for the G2. He first borrowed a G1 from a guy, that one was better than his computer so he decided to buy the current Aries.
He still has a computer and NAS for storage, then files go to the G2, then to the Lampi. He uses Roon.
The G2 was an improvement especially in the bottom end, went lower and more authority.
