I can see both sides of the issue.
I'm not actually disagreeing with you that gapless should be present, and work properly; I'm just saying it's not a
deal-breaker for me.
I fully appreciate your standpoint.
Please don't hate me for saying this, but, as a workaround, I would venture that you could format your memory cards to NTFS and then concatenate your classical tracks into single-album-files.
I appreciate that one shouldn't
have to go to that hassle, but maybe it's worth making the effort for a DAP that offers so much good stuff for an extremely reasonable $350 bucks.
Just sayin'....
