I think it’s more than that. It is not possible to think of any other speaker in such a small room apart from AN-E, tannoy, or corner horns, definitely not big cones or horns, and he had Goebbel Divin there before. The cones are in the corner. The room iirc is just 14x13 or so in the main area with the front wall additionally curving into the bay window, this curve can be used for gear not speakers, but the rack hasn’t been placed there and the empty space helps the music.
Yet with Stirling’s set up they pulled it off and that room sings However having heard two other Stirling rooms, one with CH and Rockport Lyra was just like the Caesar’s description of CH and other CH I have heard, so clearly this room with CH and Stenheim did something right and special. Interestingly the room with the Rockport has the rack in between, while this room has rack at the side, and with the same electronics, the depth and flow of the orchestral stage is much higher here. Another room with the Ultime 2 also has the rack in between and lacks that. I know there have been many discussions of how much impact can taking the rack out of the middle make, but surveying these three rooms at least for me is sufficiently strong case to keep the rack out of the middle (three rooms of which two are Stenheim Ultime 2, two are CH, all three set up by Stirling).
