Hi Diki

One of the many advantages of attending the keyboard festivals is live comparisons between instruments, including with the same sound systems, also I always take my own Grado headphones to use and thus take the speaker system out of the equation.

With the Ateliers there is normally pre-owned instruments available, (The previous generation use the same sound engine as the G70/E80 series) and therefore it is quite easy to compare old with new, (Organ cabinets and speakers are pretty much the same) and I can assure you that there is a magnitude of difference between the 2.

Many professional artists as well as home users play the Atelier organs and have upgraded to the new models, (No point upgrading if there is no improvement) and consequently I have purchased a number of the professionals CDs (Both old and new) which easily show the difference between the 2, (Not as much as live, but way above any online mp3 demos that are out there)

Hope this answers your question.
Regards

Bill
