Summary:
The NSM 20M is the masters of monitors, hand built in New York USA is reputably the most level headed full detail speakers in this competitve relm.I would say that it can even out perform top range Avalons on clarity and detail and sound performs well from the lowest audible range to a blasting of a pure 80w foundation rumbling blow.
The speakers tell of the most normal looking unassuming black box. I could pick up a whole lot music and variations everytime I listen to a piece of vocal from any other monitors. The 20M really delivers.
