Started with the Bright Star 19 sandbox set upon a shot and sand packed Rack of Gibraltar. Still had some mild acoustic breakthrough problems due to being located on a sprung wood floor. Purchased a used Airmass 19, placed sandbox on top, and that did the trick. Unwavering pitch definition regardless of the severity of the dynamic assault. Creamier vocal, string and horn textures. Big, big tuneful kick drums, double basses, and tymps. I'm very pleased.
