Bluesound Node 2i here. I recently added an SMSL VMV D1SE, mostly because I wanted to locate my digital gear across the room from my analog gear and preamp, and the D1SE provided balanced outs. I didn't really expect a difference, but I got one. Mostly, I notice I can listen to the Node all day now if I'm too busy to deal with vinyl, where before I got listener fatigue after about 3 hours. Badly mastered digital recordings are still bad, but I think there's an improvement with well mastered digital recordings.
I did not do a side by side comparison so I'm reluctant to describe any differences other than the listener fatigue, but that and the balanced outs made me very happy with the purchase.
