Well, I thought that a DAP is more than just "sound quality". Other things matter as well, like size and weight, build quality, battery life, software, features, etc. I know that sound quality is a rather important aspect but it hasn't been an issue since like... forever.
I'd rather have a worse sounding player (i.e. sacrifice one "zero" after the decimal point in the specifications) that doesn't annoy me when I use it, than have the best hardware that would be crippled by its software. However, it appears that the last part is applicable, more or less, to all DAPs nowadays. All manufacturers try to cram whatever hardware they think audiophiles would like to see, but ignore the software.
Hence why I added "with maybe a DAC/amp" in my post.
I agree. As I stated above, DAP manufacturers began trying to appeal to audiophiles, which means using all the right hardware -- the chips audiophiles like to see on a tech specs sheet.
I still have my Sansa Fuze and Sansa Clip Zip, the latter of which I still use.
