The MPX100II I have at home has no extra weights and feels fine. The MPX 1Z i've referred to has the feel of a cheap spinet. There is nothing to "dig" into when playing. Perhaps it can be adjusted, but I have my doubts...

>>> Sam, piano technicians spend their entire careers studying touch weight. Not only is there up-weight and down-weight to consider, there is also friction. One of the really nice things about a DKV is to watch the ppp numbers to show you where the friction is. Without going into this amazing science, the problem seems to be that you like an extraordinary heavy touch. My suggestions would be:

My 1997 DKV U1 at home has no weights, but the action is very nice. The MPX 1Z felt super-light, with the illusion of a short key dip. My tech showed me the round weights in the keys. Unfortunately, I would never add weights to a DKV as it might gum up the works.

I own two other U1s, (one DKV and one non-DKV) and I really feel this piano is inferior in action and in sound. I'm surprised, as it is relatively unused, the DKV functions work fine, but playing the piano is nothing like the other two and just not a good experience. Very disappointing, as I wanted to buy this for my studio for teaching purposes.
