Hi,

I own a DGX-305 and recently tried out the DGX-620 (aka YPG-625)

The 625 has impressive piano sound that is much better than the one on the DGX-305. The weighted action is somewhat light compared to a real piano but you have to try it out to see if it works for you. If I had this keyboard could record all my classical piano compositions and probably get inspired for many more. In my opinion that keyboard could be used as a replacement of a real acoustic piano.

The only new voice that impressed me (apart from the live! piano) was the cool! rotor organ. A big advantage is that using the weighted action you could control the sweet! soprano sax much better and play very expressively.

However, I decided not to upgrade to the DGX-620. Reason - that keyboard offers too little above the DGX-305 in the sound department to justify its price and fit my needs. Some guitar mega voices and 4 variations per style would have been nice.

On the other hand, if you are looking for a keyboard that is basically the DGX-305 with a better piano voice, better speakers, full keyboard mode and less 40 lbs, less than 800 EUR/$, I agree the YPG-625 would fit your bill perfectly.

Regards,

George
