Best speaker/system piano concerts

I have B and W 802 D3s. They are superb with piano music of all kinds.
Many people consider the B and W 800 series the best transducers 
for piano music on the market. The sound on mine is very hard to distinguish from the real think and I have a steinway for comparison.

Have you auditioned the newer Maggie 3.7is and up?  They are magical in their reproduction of any stringed instruments.  I assume this is in part related to their being line sources which function more like strings than cones or horns.
 I suggest the newer upgraded models because the tweaks to the ribbon tweeter make for seamless transition with the planar magnetic.  
I agree that they do not produce as much energy below 40Hz as some might wish for.  They are marvelously fast and articulate.

I have owned a Bosendorfer 275 9ft concert grand for 30 yrs and love it but it takes careful tuning and voicing. I have performed on Steinways, Yamahas, Baldwins. My favorite is is the Bosendorfer 295. A beautiful instrument with weight and velvety highs with long decay. Malcolm Frager playing Chopin on Telarc and Ivan Davis playing Reminicences of Norma live are superb. The 2 Brahms and Ravel p.c. are lovely. A list of pianists and their works is another topic.
I find my Apogee Divas (Graz refurbished ribbons) and Scintillas driven by Krell amps and Audio Research tube preamps to offer extremely realistic reproduction of these pianos in my 20x27 listening room. I would put this system against any system today for classical, jazz or folk music (they are fine with rock but use a bit more punch). They offer a wide and deep soundstage, lightening fast, floating a lifelike image without inflating the size of the instruments. Only vinyl (Mapleknoll table) really can do justice to the dynamics and timbre of a concert grand with an orchestra. I have not heard a speaker system reproduce sound better - at least none under 100k - and they are 28 and 34 yrs old, respectively. I have not heard the Maggie 30.7 yet, but I'm good!!

Without a doubt Halcro 38 (which I have), or 68 for the  power amp plus their 8 or 10 (which I have) for pre. Seldom available 2nd hand ,but WELL worth waiting for. Agreed - ATC, or you could audition some von Schweikerts (from the VR4 upwards). As an aside - do hope your listening room has proper acoustic treatment, (this is a sine qua non !).
