These speakers sing with tubes! I have heard them with the BAT 75W monos and the Atma-Sphere MkI's. In comparison, ML 33H's with these speakers sounded ho-hum. Sure, the latter were "faster", but who cares about fast if they do not play music. I agree with Jtinn unreservedly, these monitors demand tubes. My preference is to avoid low output SETs because of their bass deficiency.
