That's a LOT of DAP for the money. Recently auditioned another premium dap @ usd1,999, the tuning resemblance is very uncanny. maybe a bit refined, sure.
Considering that it is almost 5 x the 160, it should sound better, i could care less about it, since its a native file player only.
But still, this decision rests on you...
Cheers...
I'm not eying those premium DAP. There are few used units (ie: AK series, Opus, Onkyo, qp1r) with advertising price around the same price of a new mid range DAP (ie: DX160, R5, M11). I'm just keeping my options open within this price range.
