I did a side by side comparison today between my newly built pair of N3S and my N2X. Overall sound quality is very similar between the two speakers which is to be expected since they both use the same Neo 3 PDR magnetic planer tweeter and curvilinear cone woofers. They both have a very detailed and open sound quality with excellent imaging and depth. Since the N3S is a MTM design it does have higher sensitivity, wider dynamic range, and a larger overall sound. Also, since the N3S I built have the platinum bypass capacitors, they sound slightly brighter and more detailed with an increased sense of space in the music compared to the N2X which only have the Sonicaps and Mills resistor upgrade. In my opinion the N3S seem to be better suited for far field listening in a medium to large size room while the N2X seems to be better suited for near field listening in a small to medium size room. Bottom line, they are both excellent sounding speakers but their performance is affected by the room size and placement.
