This is in my opinion a really good piano library and especially considering it's price and size, the clarity is great and you can hear lots of detail in the overtones. I have the Garritan CFX too and it does sound less sampled but that's because it's also takes up a lot more space on your HDD/SSD so not a fair comparison, however i think what's missing on the Garritan CFX is the clarity of the high notes that the Signature Grand has
