Hi
Rick, I don't think Yamaha use the English language in a wrong way.
P70 is a digital piano
DGX-620 is an arranger
All that the both keyboards have in common is the GHS system. Grand Piano patches are different. I presume the P70 sounds better.

I think that Ian's sentence
Quote:
Very nice piece.It is not light,nor was it meant to be...it is a home piano,not a portable keyboard.
was confusing. In my opinion DGX-620 is as portable as DGX-505. I think the major problem connected with its portability of these 88-keys is the size of the keyboard, not its weight.

Anyway, are 18kg too much for a portable keyboard? How much a Tyros 2 weights?

Regards,
George
