How to reproduce sound of piano

Wow thanks for all the responses. It appears that the task is much more daunting than I imagined, but that makes this hobby the more exciting. FYI, my current system is in my condo but I'm planning to build a dedicated listening area in my weekend house so the space is no longer a factor. So from so far, looks like right speakers with good subwoofers and a top notch turntable is the way to go.

As a side note, I forgot to mention that my Grados GS-1000 headphones actually does very good job with piano (much better than speakers). Right now, I listen to most piano works on my headphones. But given it's a can, it lacks soundstage and the music is in my head so I only use it for solo works where soundstage is not as important. Anyone else feel that best headphones do better justice to piano than most speakers?

So it appears getting the right subwoofer is absolutely critical first step in this endeavor. I find that ironic given many classical enthusiast probably consider bass the least important characteristic when selecting speakers. I up to now thought subwoofer was more for home theatre and not for serious musical reproduction. Thanks again for all the suggestions. Anyone recommend a good musical subwoofer that's physically compact?

Well I got a Velodyne Optimum 8 subwoofer today. I'm having bit difficulty seamlessly incorporating it. I can either turn MA2275 bass control (-12 db at 100hz) down and cross over at 100 hz or just try crossing over at lower frequency ~65 hz. Any suggestions? My first foray into subwoofers and bit over my head. Thanks for all the advices.

The dedicated listening room will be long process and won't happen in the near future so this will do for now.

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.
