I never had the Snells, but I had heard something about the similarity before. What works with the Audio Notes is the interaction with the cabinet, as with a musical instument, as opposed to pretending the cabinet will not be part of the sound. The Conquest monos are a great match, but I was surprised to hear how well the very powerful GamuT M-250s made music. Very three dimensional and more dynamic. They don't quite have the holographic presence of the tubes, but they come close.
