Sony DAPs are quite different from chi-fi in design and implementation (i.e. no off-the-shelf DAC and amps). It might be best to take a look at the specific threads here in the forum. I think they sound great, but like many things hi-fi, opinions vary:

Thanks. I own Sony Daps. ZX2 & ZX300, & happy with them. You have been listening to Apple Music on your model ? If so, are you happy with it ?
