Some impressive rooms!
I've just gone through a major shift from Soffit speakers to floorstanders. It changed literally everything! I had to go to a smaller desk, put the screens to the side, add feet to the speakers to get the tweeter to ear height, then add a sub due to the lost rumble of the speakers being raised.....sigh. Big job.
It changed my workflow a bit but my work sounds better. Main gear in a Sterling modular plan A. Side rack houses comps and converters. The monitor stand solves most issues other than my left ear get more attention when I'm editing or if I'm using plugins.
