I'll disagree after hearing the three of them all side by side at a G2G.
+1. I was at the same get together. FWIW, the Vega stayed playing well into the night. Different flavors between the three, although the Vega was definitely more sophisticated, detailed, full bodied and anchored. The other 2 were not bad at all, with the Gustard tending to a more smooth sound. The Yggy I didn't listen to acutely.
Surprisingly the Vega's little brother, the Aries mini was quite good, as was the internal dac in Vinnie Rossi's LIO.
