You play the violin? So do I! Who made your voilin? Full size?Type of wood used? Who made the bow? Horse hair or synthetic? WHat kind of strings do you use? How do you store your Violin?
Funny that you mentioned Violin's. I used to appraise them part time in Ma. to help pay my college tuition a few years back. It was a very enjoyable job, very laid back, but I learned alot about appraising,repairing, and even mfg. techniques used by old school string maker's in the area.
Steinway Grand too eh? Really? Which model does your wife have?
BTW, no opinions on my part,ALL facts until you can prove otherwise(and that isnt going to happen because I doubt you would ever be foolish enough to take on a bet you cant win). And you know how you can do that. Take me up on my offer so I can make you(your ears actually)look a bit foolish in person. Ill bet ANY amount of money you couldnt tell the difference between a Yamaha YDP223,a Yamaha U-1,a yamaha P-22,A Samic SIG50 a pair of Dunlavy SC-IVA's and Revel Salon's(I wont include the ML Prodigies because they have an easily identifiable harmonic distortion thats easy to pick up on, just like all planer speakers have)You would have 1 electric piano, 2 vertical's and one grand piano along with 2 pairs of full range competently designed speakers. With no visual que's you would NEVER be able to tell on a consistent basis if its "Live"(a real piano) or "memorex"(floor standers), let alone which model is playing(well maybe the electronic piano on a good day). If you feel otherwise, next time your in the Boston area, be sure to swing by.
But in all honesty you should have read some of the other posts above a bit more carefully about being able to discern the differnces in piano harmonics and full range speaker without even knowing what the actual piano is supposed to sound like in the first place from the original recording. There is no opinion to this, just a plain simple fact. If you dont know what the piano sounded like exactly to begin with before being recorded, how can you tell if the recording or speaker is faithful in itself to the original track? You cant, just like you cant make the original statement you made. And that my friend IS FACT.
