Hello Niels,
The Tyros2 sounds fantastic in my opinion because I do like the sound-image.

To be honest I think your conclusions about the T2 polished sound is slightly premature, because you did not hear, touch or play the T2.
Those guys who DID hear it live....say it sounds AMAZING !!

Never before I heard saxes, brass, guitars with this great quality/characterisics / precision.
Absolutely no 'polished'- but REAL saxes or brass. The SAV (super articulation voices) system surely is the best 'invention' in music since years.

Did any other brand invent something revolutionary keys-stuff the last 5 years ? .... if yes, what was it ?

In fact the G70 was advertised as "The best of all worlds packed in one workstation"
(nothing spectacular new)

Please enjoy the G70.... at least I will enjoy the Tyros 2 for sure
