---------------------- multipart/alternative attachment Andre, I've read the article, and I have the samples of the punchings you sent me. I'd like to buy a couple of sets. What I'd like to do is install them in my piano and play them over a long period of time--if I ever get the time to play my own danged pianner! Lemme know who's selling them here!

My instructor there, at the time, showed me the difference between the smaller side of the punching up, and the smaller side of the punching down. It did clearly make a difference in sound. One thing I have learned about this new Wurzen punching, is, that if an instrument has not been regulated the right way, or when an instrument has very loud hammers, you will not hear any difference. You will hear a difference though when the instrument has been regulated the right way, and when the hammers have a more or less 'normal' voicing, i.e. not really too loud, and not really too soft. There is of course a wide scale between very soft and very loud, but then..... those two are extremes. The influence of the new tapered Wurzen punching is subtle, and can only be heard on an instrument which has been regulated and voiced according to 'normal' professional standards. The feel/touch of the new punching on the other hand, is an other case : 'any' regulation becomes more clear and more defined when you install these punchings. How can it not be the case? It is a more dense material with a very satisfying elasticity which Vladan Temer described so clearly before when he tested several kinds of punchings. That means that a key dip of 10 mm is a key dip of 10 mm. No more, and no less. That in itself makes all the difference. ---------------------- multipart/alternative attachment An HTML attachment was scrubbed...
