Hate to throw some confusion in the mix, but I figure if I'm confused, I'll try to make sure everyone else is, too. I have on hand one set of Voici Armoniche D reeds. They are larger than Binci D's, in fact they are the same size as Binci C reeds, especially on the low set. I also have on hand one set of Cagnoni C reeds, which I was told by a well know builder, are bigger than Binci, mine are not only smaller than Binci, but they are shorter by quite a bit.
So, with each company, there are different dimensions for each key, and it depends on who ordered them, and what that company had available. Apparently sometimes, certain folks can talk a reed company into making reeds to certain specs, then that may not be available later. I know that was the case with Binci. So if you buy all your reeds from Greg Mouton, you're liable to get them a certain size, but if you buy some from someone else, like I did, you may possibly get some different dimensions. On top of that, there are different profiles and shaps.
Because if you wanted to change a C box to D or D to C you might be able get and install a set of reeds that are the same size (although different key) and save a lot of work in cutting or filling the reed boxes.
My C-accordion build by Junior Martin is equipped with Antonelli reeds.
It was a Bb (Binci) and the reeds were changed to C(Antonelli) by a friend. He said that the Antonelli reeds were stronger than Binci, so it would take a longer time to play them in pieces.
I thought that Nout did something with the old Bb reeds.
At link#2 you can hear us play a song with that accordion. Link#3 brings you to the website from the manufacturer Voci Armoniche (Antonelli & Salpa)
I'm very satisfied with the sound of my C accordion.
The reed starts cracking side to side, usually toward the rivet end. A break is usually pre warned by a wonky sound from the reed. I have owned 54 accordeons. I have never broken a reed.
I have had 3 accordeons with Binci reeds and about 20 with Antonellis.
Here is another differentiation..
The majority of the Antonelli reeds found on boxes in the US are "tipo a mano" not "a mano"..
Castaganari, considered by many to be the best production box made, use "tip a mano" Antonellis as standard.. Bincis on request. Hand made Antonellis on request.
The majority of Binci reeds are true "a mano".. not "tipo a mano" so an apples to apples comparison is not usually a fair comparison.
Also reed sellers are prone to sell Antonelli "tipo a mano" at the same price as Binci "a mano"..
If you are buying Antonellis...ask if they are "tipo a mano" or "a mano".. pay a fair price.
I personally prefer Antonelli "tipo a mano" , however this is also a matter of the tuner who sets and tunes the reeds, and because I am used to them.
