I'm an enthusiastic owner of the Paul Hynes SR3-12 linear supply. The build quality is absolutely-off chart and the performance is there in spades. Relative to the wall wart running my PaceCar 2, the Paul Hynes supply tightened up the bass nicely and solidified the middle of my soundstage considerably. It didn't give me a larger stage necessarily, but instruments and vocals are anchored much more firmly within the existing boundaries. Uber-highly recommended!
