Not all Steinway's are made alike. Certainly the company took a dive during WWI and after but Steinway still a reference piano. I have a Fazioli and a Steinway and love the sound of the Fazioli over the Steinway.
As for sound reproduction...you might try a Theta Digital IVa with powered speakers. I personally prefer ATC actives...all the way around. 150a for the front, 100a surrounds, 25a for the rears and the C6 center and C6 sub. The sound is silky smooth when it needs to be and explosive when it needs. I don't hear much color to the sound. jmho
As for headphones...I have MEZE Empyrean's. With a good DAC...even portable...it is the best sound I have ever heard in headphones. Again jmho
