As a Steinway B Grand owner, I'm admittedly spoiled by it's rich sound and beautiful harmonic overtones so well suited to classical repertoire, and generally dislike the colder "clinical sound" of Yamaha "acoustic" grands. Considering this, I really like Tyros 4's new "SA Concert Grand". It's perhaps the first of all the Yamaha Tyros Piano voices that I'm very happy with. Strangely enough, other than it included in the name, I can't figure out where its super articulation comes in. With all the different Tyros 4 pianos voices to choose from (SA Concert Grand, Live GrandPiano, Super Articulation Pop Grand, SA Ambient Piano, SA Cocktail Piano, SA Piano Orchestra, etc) and the ability to easily mix, match & layer: via RH 1,2,3, everyone should be able to easily come up with a Tyros 4 piano to their personal liking for any playing scenario from solo to big band.
