I have to agree with GoKuss4, I'm really not a big fan of the Default Grand Piano on the Audya.
In addition, when you add a second voice with it, the default is a pad. Should be STRINGS!
I took the Vintage Grand under programs and did some editing and tweaking and came up with a really nice sound, plus strings are the second voice default.
If anyone has heard the Piano on the Korg Kronos.........maybe you'll agree, That is an AWESOME PIANO!
