This post has a few facts, a few opinions, and a question. Please keep in mind that I am not trying to maliciously rain on anyone's parade, and that in particular regarding the question, that this is not a personal attack, it is a request for clarification.

Well this is interesting. When I record direct to the HHB 850, I hear the string clealy on a pair of Koss headphones . the kind they rent to you to watch a movie on an airplane. I think the MP3 format can't handle low end.
For what it's worth, with my ears and my soundcard and headphones, while I get sound and not just clicking or warble all the way down, I would only call "musical" what I hear down to the A#.

I have spent considerablr time voicing 32' organ pipes
Maybe we're thinking of two different meanings of the word "voicing" here. Are you saying that you have worked as a pipe organ technician, adjusting the mechanics of organ pipes?

and that Bosendoerfer has a low F# . What acoustic or acoustic electric instrument has a C# 00 string ?
For the record, a standard piano goes down to the A below a contrabass low B. (Opinion: until you get up to a decently sized grand, or a very well-made large upright, anything below the standard bass low E or the D below that sounds poorly.) Bösendorfer makes two extended-range models. One goes down to F, 1/2 step below the F# of a subcontrabass; and one goes down to C (that's right, 16.35Hz!) 1/2 step
below the C# of the Adler ("Jaquo's C#").
The Low C Bösendorfer is 9' 6" long, with a low C string that is probably at least 8' long, in order to be able to have a string held at high enough tension to get some good tone out of it.
