Ok i am on the verge of buying either a smartphone or a Walkman, my main aim for this purchase is to get the best sound from a portable device for personal audio. It's no secret than sony's latest experia Z2 has been rated higly for sound by What Hifi stating Incredible Sound on it's review.( am i right in saying this is without Hi Res Audio, and it's seems What Hi is wowed with the sound. Now, looking at Sony's latest attempt at a Hi Res Walkman i feel What Hi Fi hasn't praised the sound as much like they have done with the review of the Xperia Z2, question is can sound from a player without Hi Res sound better from a player with Hi Res, if so what is the point of Hi Res Audio??
