Nor does it have the same quick response and feel of a Castagnari. Nor does any Cajun Made box I have owned or played compared to a Castagnari. I would note the Castagnaris use hairpin springs similar to Hohner, not coils.
I like Cajun made boxes for the colloquialism and folk/art connection.

Who worked on your HA 114 and what did they do?

Revalved and rewaxed and retuned. Buttons padded ? or better yet a replacement fingerboard with access panels and a thumb groove.
Upgraded Bellows. Reface the bass valves ?

This is a bit of work and money, but the results are worth it to some.

I have some that are modded and some close to stock. I like them all.

I still recommend getting a new Cajun made box from the sources posted. In my opinion a better value than a used Martin or (currently made) Acadian.

Best of luck.

One other note..

I went full circle, from Hohners to successively better accordeons , to Cajun made, to the very best (IMNSHO) Castagnaris which I still own, and back to Hohners.

I prefer the top and the bottom to the middle.
