Hi Nils, If it ain't broke don't fix it. If you really like it the way it is then keep it that way until you have cause not to like it, then consider it. On the other hand, if you like power and performance then go for it. Lots of people buy Porsches, not because they need one, but because it has the power and performance that pleases them. If there is a piano with a real problem then it is time to get out the weights and scales. The only question that remains, is the original factory set up optimum? No real way but to weigh and calculate. Trick question and tricky answers. Newton
