Just get a RS2 from a local shop, very handy little player, solid built. Comes with a leather case which is fitted tightly.
First Impression, kinda of Sony's tuning, warm, organic and musical, yet not that booming. Female vocals is quite addictive liked the older generation of AK DAP with very beautiful instrumental performance. The background is clean and dark, half of the volume (4.4 Low Gain) can drive my planar HOOK X well. The light at the side turns orange when playing lossless, and turns blue when playing hi-res.
I am so impressed on how good the RS2 sounds with its size. Its SQ is way better than the R5II ( I tried before ) to me. It's simply more refined than the DX170 I try the same time.
If bluetooth, wifi, streaming is not what you are concerned for a new DAP, then RS2 is good to go !
