Re: Adjustable barrels any good?

I wrote this in a previous thread about the Paulus & Schuler Zoom barrel:

On my Wurlitzer Reform Boehm's it doesn't either improve or harm the sound. The latter is somewhat impressive though, since most non-original barrels that I have tried through the years has been negative to the sound.

When lowering the tuning it must be turned out longer compared to the pullout of a regular barrel, probably since the gap between a regular barrel and the upper joint tenon is missing and thus no added internal volume is created that way.

The throat tones gets just as flat as with a relatively shorter pullout of a regular barrel, when lowering the general tuning to the same level. An exemption may be mouthpieces that creates drastic flatness of the throat tones at the slightest pullout, as at least some mouthpieces with Austrian bores on German bore clarinets. In these cases the Zoom barrel may actually even out the scale a little bit. At least I have a feeling of that, but I just haven't made the effort to get solid evidence.

I didn't find any improvement in sound with a turned out Zoom barrel compared to a pulled out regular barrel - despite the claim that a maintained "wood-to-wood" contact between the barrel and upper joint would have such an effect.

My findings about sound were based on recordings of the entire chromatic scale of my clarinets (up to d#6) and then a comparison by a playback of three notes at a time in instant succession with either the Zoom barrel or the regular Wurlitzer barrels.
