What are the best loudspeakers under $4000 to re-create lifelike piano

@martykl - not sure if you were referring to my earlier post about the Nord not sounding like a real piano (or a Rhodes for that matter). Just to be clear if you were referring to my post, I wasn't talking about the recording process, digital v analog, but the instrument itself. Yet, at least live, I've heard some electronic keyboards that do a pretty impressive job of emulating an acoustic piano. 
On the history of pianos, those old "reproducing pianos" (which were more sophisticated than a plain 'ole player piano) could let you hear Gershwin playing his compositions. Crazy. Apparently, some (or all?) have been ported over to the Disclavier. 

I love the sound of the piano that my Harbeth C7ES3s produce.  Very natural and life like depending on the quality of the recording  and source of course. 
Joni Mitchell records sound amazing, as does the David Bowie "Alladin Sane" album.  So do certain Bill Evans, Oscar Petersen and Thelonious Monk recordings among others.  The Harbeths can deliver like no other speaker I have owned.

I have the latest Nord 5. Like anthing it does some emulation better than others. If you go to the online library you can fine tune. For Rhodes emulation I prefer the Korg SV-1. The Korg SV-1 doesnt do piano as well as the Nord but it does Rhodes well and it has a weighted keyboard for a better piano like playing feel (my Nord is best suited to Organ with its waterfall keyboard) and organ drawbars)

I plug the Korg SV-1 midi out into the Nord and the Nord produces the piano emulation, mellotron, farfisa and other sounds I need. The Korg does a great Oberheim too.

In the end I settled on these two keyboards for the majority of needs. The split function allows me to use both keyboards sumultaneously for different instruments. Neither the Korg nor the Nord do everything well but together it is like Jack Spratt and his wife - got most everything covered to a very high level of authenticity. Short of buying and servicing all the original instruments - i would need a dozen or more keyboards - I find this solution superb.

I am not sure what Nord you have tried but there has been significant improvements over the years. Also the speakers you choose to connect to tbe keyboard are critical - Genelec 8020 are very good for the nearfield sound of the listener while a keyboard amp is necessary to achieve high volumes in a band setting where you compete against drums and guitar.

@shadorne - thanks for all of that. My Nord is older- probably 8 or 9 years? I had a Motion Sound? amp- not sure it is still in production. Now that I'm in Austin, it's on my list to have the amp repaired or replaced and update the Nord. I actually did like the B-3 emulator, which is mainly why I bought it at the time, but I don't play professionally, so my dabbling in electronic keyboards isn't that deep. I did play some Yamaha electric pianos at one point that had good feel and sounded pretty good. 

Where the @#$&!! can you hear any of the upper-market Silverlines on the east coast/mid-Atlantic?
