Thats fair enough, and I would agree actually. But still a declaritive is just that, and personal experience in this regard is also influenced by our subjectiveness. Until our observations are quantified and documented...we cant really hope to convince more then a few of our position. And remember all those folks out here reading.... how are they to know who to believe ? > The difference between some writings and others is > that some others don't accurately reflect what is actually seen and heard > in pianos.

Del even cautioned us all that Dan is a guy who has done a lot of work in the area and is not to be taking lightly.... > So what constitutes proof? A good question... and to get at that (as far as that is possible) we first have to sort out the differences between subjective ideas about "tone quality" and physically tangebles like string buzz, sustain time, power, and the like. > A published book, or > patent? I can see where speculation unsupported by logic, physics, and > actual prototypes would be suspect, but I thought you said you preferred > untuned duplexes. Why is that? I do because I have detuned duplexes on near 30 instruments through the years following Ed McMorrows advice and proceedures, and each time I find the sound much cleaner and that whooshing / whistling effect common on tuned duplexs all but dissapears, and doesnt come back. This echos some others experiences I know...but to no small degree this reflects my own personal preference for piano sound. and thats a far different thing then being able to declare the detuned duplex to be unconditionally better. Besides... I know quite a few pianists that actually like that whistling effect I detest so much. They call it things like "exciting" and "lively". As far as sustain times and the like. I have never had the opportunity to accurately measure the differences, and as far as I can tell no one else has published any hard data directly relevant to these more quantifiable issues either. It might be nice to have some of this data available so that our more subjective observations relating to tone quality may be viewed in the light of such material. > > Beautiful Autumn day in my neighborhood. > > Ron N That plants a nice picture in my mind.
