It is a nice piano. I like it better than Yamaha C7 and Kawai RX-6, that are about the same size (c7 a little bigger). For that money, though, August Foerster make a better instrument at 215.
You know I like my Irmler better as well, although to avoid confusion, my Irmler is quite souped up. I have never played an Irmler out of the box.

Thinking of ditching the C5 already?
