I moved from a Bluesound Node 2i to an Auralic Aries G1 with both feeding into the DAC on a PS Audio Gain Cell.
The Node 2i is a great product and I always thought it had a great sound and features for the money.
The Aries G1 is a step up with great detail and overall SQ and is built like a tank with two heavy duty power supplies. The Lightning DS application is also a huge step up from the Bluesound application with a lot of features for those that like to fine-tune output settings.
