I popped over to Chappels of Bond Street during lunch today to hopefully try the new NU1, but didn't see it, so tried out the AvantGrand instead.
Compared to my teacher's C3, I felt the keys were lighter. Not necessarily bad, just different. It felt amazing under my paws though, definitely a big step forward from my CP33, and I felt I could pull more dynamic range out of it.
The speakers on it didn't seem to generate the kind of bass I'd expect from a grand - my teacher's C3 sounds way bigger, but it is impossible to compare since they are in totally different acoustic environments.
I was testing the AvantGrand with To Zanarkand, the only piano piece I've committed to memory. As luck would have it, there was a fellow final fantasy fan in shop (from Norway!) - and I was wearing my distant worlds shirt as well :D
