Well Joseph, we've had many little conversations about accordions in recent weeks and I think we are able to give honest opinions to each other about music, accordion sounds, designs etc.
Firstly, I have to say that you play very well and most importantly, you are highly MUSICAL, because you bring the notes on the page to life when you play. If a person can do that I personally don't mind what kind of instrument they play. Musicality matters more than systems or methods of sound generation.
Secondly, I consider both renditions to be lovely. However, I personally think an accordion player should, if possible, always have one acoustic accordion option, which you do. You have many fine and rare accordions! However, I don't dismiss the digital accordion because it can be an instrument to give different sound options - like the piano tone you have used in the performance, which was really quite lovely.
If I am to give any more 'in depth' analysis, I would say the Giulietti is great and has a noble tone, but that the 45 key keyboard is long. I like the 41 key size best. If someone needs the extra 4 notes, I think 19mm or even 18mm key width instead, can make it more compact. Regarding the Evo, it's spot-on for you.
