Thanks Eric.
While my wife was out this afternoon I put the N1X's in the living room system beside the Klipsch RB-81 II's and used an SPL meter to determine volume settings that level matched the two sets of speakers. Then this evening I had her audition the two speakers.
Right from the first piece of music, "The Sea and Sinbad's Ship" from Schcherazade, she preferred the N1X. The preference held up and was reinforced with music from Adele and Fleetwood Mac. Even though the RB-81 II's have almost twice the internal volume as the N1X's and have an 8" woofer vs the N1X's 5 1/4" woofer the N1X's bass response was much fuller, smoother and better balanced. As for the highs, the Neo3 PDR is exceptional.
The last piece I played was J.S. Bach's Violin Concerto No. 2 in E, Allegro. With the Klipsch's she listened but when the N1X's were playing she was sitting on the couch with her eyes closed playing an air violin. She said that sounded like a real violin, like being there, smooth, buttery and relaxing. She was more than favorably impressed.
Then she asked if the ones I am building for the living room will sound as good. When I told her better her eyes got big and she said "Oh". I have started building the cabinets for a pair of N3TL's that I'm going to upgrade all the way, including platinum by-pass caps. She even picked out the veneer she wants, South American Rosewood (Rosewood "Santos").
The N1X's are the best sounding speakers I've ever owned, at least until I get the N3's built
