Brad, the Symphonias I heard were in a 7.5m x 3.5m x 2.5m room, L shaped at rear half, the 70W Cerat monos, Kassandra dac w transport and Pang server
I was hugely bowled over by creamy, full mids/upper bass, natural non etched treble, dynamic ease and full texture.
But low bass was too floaty for me. Basslines, electronica, harder hitting rhythmic material felt a bit ambiguous, and gave away the presentation as not being realistic.
Have no idea if this was the Symphonias bass, or a horns/room interaction. I've heard Cessaro Liszts in a different way not meld with a room.
The Pnoes I heard at the General lock step in his vast 450 m*3 room on 1.46W, so it can be done. But my likely only exposure to Symphonias, like Liszts left me w the "fantastic, but if only..." feeling.
