Thanks for the info Artstar. I would try it out unfortunately it's not here yet in my country. Am,thinking of shipping from Japan. I guess what I am trying to figure out if there is any significant advantage of having a dedicated player in my setup......the Sony is very interesting to me over the cowons, iriver, and basso players due to the Android Ui and relatively cheaper pricing......
To give you another view on this matter , I strongly recommend you read this review so that you won't feel so frustrating after buying any audio gear at this price range

My point is you should not raise your hope way too high when buying these luxurious items , especially at much lower price 100$-200$ it's not rare to find an extremely bang for the buck value . This is almost absolute truth when you are just a casual audio enthusiast , of course there are differences in sound quality reproduction between 2 polar of price tag but mostly they are noticeably perceived only by experienced enthusiast , long time reviewer and ppl with God ears/critical listeners . Without A/Bing 2 pieces of equipment one after another , I find it hard to notice much improvement to justify the price (sound wise) when casually listening .
If you are looking for the best sound quality for the price , you care more about IEM , where improvements are more to say than among DAPs , still sound wise , a twice-the-price good IEM is not really an upgrade of a great IEM.
Back to the ZX1 , to me a no-expert-in-audio-world-at-all , what clear improvement you would get after your purchase is an Android device with 128GB storage, good battery life so you don't have to drain your smartphone and a kick-ass design that beats everything else , of course only applied if you like that looks , a middle finger to every mainstream super slim incredibly fragile looking gadget while still boasting class , appeal and trusty, durable look. For more style points , add a big smart watch (don't use smartband) and a cellphone from previous generation , W995 for example
Seriously though , my advice is , find something you like , search some reviews about it , if most are positive , descriptions match your taste , buy it and look no further , read no other products' review . Ignorance is bliss , don't care about there is something a little better for the price or something is not as good but way much cheaper . If you have the money to buy a good item that suits your taste , be happy and enjoy . Or like me , read everything to know its pros and cons but overlook any disappointment and enjoy it for what it has to offer and the reason why you choose it in the first place.

No worries though , just remember you don't buy these for the sonic wow alone , it's the same thing for most "high-end" DAP , there are no day and night differences with casual listening .
