I put it in my RD700 Roland. It sounds awesome. Don't listen to the petty reviews. It almost makes it seem ridiculous to record live piano, but I do anyway for at least psychological reasons and to justify my grand piano expense.
I am very fussy about pianos too.
I do not use it as an absolute solo, however. But when combined with other instruments, even just drums, I have people with good ears that come in for sessions and they do not know the difference.
I sold my SRX-02. It sucked in comparison.
I also have a Fantom X, and I think I like the SRX11 better. I am probably in the minority on that, however.
