Classical piano is my reference, in addition to violin sonatas and concertos. I used to this orchestral works were the hardest to reproduce, but it is definitely piano and violin.
The speaker is important, but just half the equation. One can have the sense of tonality and weight, but the "aahhhhh..." factor is in the decay. If you have a system that does decay from an acoustic instrument into the venue, that is not something very common. As you listen to certain pianists, they maximize the decay effect with the speed and phrasing. Peter Takacs (Beethoven) and Stephen Osborne come to mind. Some may find them dull if their system does not properly reproduce the effect. Decay is not necessarily something I would ascribe to Horowitz, who is more about the attack of the note, joy, and the ability to always find something new in a piece.
I have a video under my system page of Osborne doing Rachmaninov. Interestingly, while the little iPhone speaker did pick-up the weight and tonality, it didn't really pick-up the decay.
