The Vienna Acoustics Mozart and Beethoven speakers, which were the direct predecessors to the current Mozart Grand and Beethoven Grand, were two speakers I looked at very closely two years ago.
I found the Vienna's sound to be smooth, detailed without being hyped, rhythmic and musical, with decent dynamics, and very good tumbrel accuracy. I had just seen Holly Cole in concert, in an intimate setting, and was listening to every speaker I could get my hands on with her album "Blame It On My Youth". I can only say that the Vienna speakers were the most accurate at recreating the sound I'd heard live... that would include listening to Martin-Logan, M&K, Klipsch, Boston Acoustics, Linn, Rega, B&W, Paradigm, Definitive Technology, Mirage, JBL, MB Quart, Monitor Audio, Snell, and Wharfedale.
I'm not saying that other speakers, or even those I've listed above aren't better in some respects... but the Vienna Acoustics and the Sonas Faber line were the two that really grabbed my attention.
