But don't you think Fiio is an unheard brand and what if tomorrow they close down or move away than its like you will be stucked with their product when it requires repair/service. In comparison, SONY is a well established big reputed brand.
The only problem over here is that unless I have both the players in front of me and listen to the same song of 320kbps on both the players, it becomes absolutely difficult to exercise my judgement. The only drawback Sony's Walkman have is the absence of Wi-Fi in which Fiio is a step ahead. Also while Fiio offers upto 384khz, Sony Walkman NW-W46HN max capacity is till 320kbps so I wonder if that really makes a difference?
The electronic consumer world has become such today that you buy and you experiment and if God forbid due to some reason the product didn't live upto your expectation than live with it forever, there isn't any refund. It's all gambling. Such as I bought this huge 65inch Sony 4k 65X8500D LCD TV with very big expectations but it totally failed in terms of picture clarity even on HD Channels via my Airtel STB HD+ Box. I gambled and now I have to live with it. Now neither can I TRASH it nor can I resale it as it won't fetch that higher resale price.
