Home demo. ProAc D48R and Spendor D9

Between the Spendor D7 / D9 and Proac D30RS / D48R, which one does piano timbre better?  I'm allergic to hearing a piano reproduction that (given a good quality recording) does not easily, clearly and immediately tells me, even if I'm not paying much attention, that this is a real, mechanical piano, not a "digital" piano. There is a very... percussive, let's say, quality especially to the upper range notes of a piano that makes the listener very much aware that there are some very tight strings that are being hit, and some systems don't reproduce this quality too well. Take, for example, George Winston's album "December", the 12th track called "Peace". How do the Spendors and the Proacs fare in this regard? 

I can state that the Spendor D7 (just below the D9) have the best piano sound I have ever heard in a speaker- better than my previous Harbeths which made piano sound excellent.  The Spendors make piano sound alive and real.  

@donquichotte,You will get biased opinion on this question because between the ProAc and Spendor owners we have purchased the loudspeakers that "we" thought, sounded the most natural to us. I have heard the ProAc D30, Spendor D7 and own the ProAc D48R. For piano, I would highly recommend the D48R. But would also urge you to listen to the Spendor D9 to see what you prefer. Both my kids play the piano and based on that experience I can say that the larger speakers get the sound "closer" to the original. But one thing to remember is - for a piano recording to sound "like a real piano" on a large loudspeaker, you need to provide them with enough room to breath. The smaller D30 and D7 also do piano very well, but the "scale" is different compared to the larger loudspeakers.

It’s a matter of synergy between speakers & system and personal taste too,the best piano sound I heard is with my Proac D30 RS ribbon twitters and with Harbeth 40.2 which I heard at high end show.

Thank you very much guys for answering so quickly!

Understood. Unfortunately, the space I have is not very large - about 23 square meters with a height of about 2.3 meters. I can get about 0.5-0.6 meters between the back of the speakers and the (long) wall behind them with the speakers spaced about 2 meters apart (inner edge to inner edge) and about 3 meters between me and the front baffle of each speaker. I know most would point out that the smaller speakers are more appropriate for this room, but... I’m not listening loud, on the contrary sometimes, and I would like to have good bass down to 30 Hz with the better mids the larger speakers are supposed to offer.

To further confuse things, I’ve read somebody prefered the mids of the D30RS to those of the D48R, stating that the midbass driver is better in the D30RS. Difficult choices, given that I’ll definitely not be able to audition in my room before purchasing...
Other speakers I’m considering are from the Spendor’s Classic line, especially because I heard the SP2/3R2 and loved them. Musical diet based on jazz, classical (especially piano) and old rock. Budget is not very clear, but the D9 and the Classic 100 are stretching it a lot, possibly even too far. Classic 1/2, maybe?

Have you heard anything from the current or the older Spendor Classic line?
