How to reproduce sound of piano

Johnathan Valin did a review of the Wilson benesch Torus Infrasonic Generator. It uses an 18" very stiff carbon fiber diaphragm that operates in push pull, much like an electrostatic. Very, very fast. Breath taking fast. Lots of patents at work here so you should go to www.wilson-benesch.com and download the tech paper on it. None better in my opinion for music. I am guessing the JR is better for home theater.
Don't be put off by the fact that I am a dealer either, I am sure you have a local dealer to audition at.

Martykl and Detlof thanks for your suggestions. I probably will get the SMS-1 in the near future. In the meanwhile, I took your advices Detlof and used one of Charlie Hadyn's deep bass CD's to find the optimal position for the sub. I also used Grados GS-1000 headphone to calibrate the sound so that the music from speakers+sub closely matches that of the headphones (assuming the headphone is most true to the recording). I settled on the left corner just behind the main speaker with 180 degree phase and 60 hz cross over (bass augmentation and not running throuh sub x-over). Also I put a marble slab below it to isolate it and hopefully to avoid disturbing the neighbors.

Overall, the soundstage has increased dramatically and now I'm getting some resemblance to live grand piano sound although still far ways to go, but a huge improvement nontheless (Beethoven sonatas and Rachmaninoff Etude-Tableaux and Preludes seem to have benefitted the most so far). Also the subwoofer has given new life to most jazz CDs I have. I never thought subwoofer can enhance listening experience this much, music just sounds much more wider and feels real. Before spending $1000+ on cables, I think all 2 channel music lovers should get a sub first.

Now that you have one sub, would you consider trying a stereo pair?
