Next step up on the streaming food chain?

I’ve been enjoying my Auralic Aries G1 for nearly 3 years now. If I wanted to explore a significant step up in my streaming quality, and not a small incremental increase in quality, what devices should be on my short list? Aries G2.2? Grimm MU1? Something else? The G1 is awfully good, however, I still perceive an extra layer of dimensionality and roundness with my analogs set up (see profile for details) that I would love too achieve in the digital realm. Or am I barking up the wrong tree, and should I focus on my DAC, a Bricasti M1, and try as non-oversampling R2R dac? FWIW, I think the Bricasti is excellent- it was the first DAC I ever heard that made me say- "that sounds terrific" instead of saying "that sounds great for digital"
