SU-8 has a fully balanced topology to my understanding. 2x ES9038Q2M chips in it.
I think in terms of bang for you buck it’s definitely the way to go. The ASR review objectively confirms it as well - it measure better than DACs way above its price point. I’m looking at pulling the trigger on one myself even though I’d be comfortable spending 4x that price - I just don’t see a point though.
