@geoffkait @audiokinesis Thanks for the comments, but there's no trouble getting proper volume at normal distance in my setup. What I meant is that my speakers probably would not be a great candidate for the OP to use to test his 50w amp.
In fact, I don't think there are many electrostatics that are a great match for a 50w amp; perhaps smaller Quads, but certainly not larger Maggies, Sound Labs, nor Analysis Audios. Barry, even if your amp sounds inherently terrific, it will mate well with a pretty darn narrow slice of the speakers in the market IMHO. Bridgeable monos? A bigger brother? Cheers,
Spencer
