Bandoneon Plates- Zinc vs Al

[Secondo Maggiore]

Greetings forumers from newbie posting. Does anyone have a link to share pls for a CONTROLLED sound test/comparison of bandoneons with reed plates in zinc vs aluminum? Of course there is no lack of videos on youtube etc for both bandoneons with Zn and those with Al. However I'm talking about the same instrument model/vintage in the hands of the same respectable hands playing the same/similar music samples on one type vs the other. Or does anyone have perhaps direct experience here?
