Here are my early less than 40 hour impressions (aging time of the player). I've listened to this DAP collectively for 6 hours:
- DSD playback: I'm very impressed by DSD performance of this player. I compared it directly with Lotoo Paw Gold which I use exclusively for DSD playback. Too early to tell, I need way more time, need to use my analytical IEM. But I've to say dp-s1 on DSD album is performing way above its price point
- ACG vs Balance: Can't tell any significant difference between the two balance out feature. On my DP-X1 the difference is more noticeable,
- Digital filter: This has to be the first DAP that I can actually hear the performance of the difference filters. Whether that is a good thing or not I can only speak of it in the near future.
- Batter life: After the 6 hour mark, however with minimal screen usage the battery indicator is near halfway mark. I play a mixture of various files, volume set at 34 using LOW gain. So far so good!
- Heat: Cool to the touch which is a change! All my other daps do get warm which means I cannot place it in my shirt pocket. I haven't yet taken it outdoors in the Sydney sun. The black color might be a nice heat magnet!
For 500 AUD delivered express in two days from Amazon Japan this player seems to slowly wining me over in a big way. Now going back on whether it truly can beat players like LPG or WM1A please remember we are talking about players 3-6 times its price range. Currently out of balance out of 1A I can tell 1A has a more 3D soundstage and a large spatial present compared to DP-S1 but honestly for what I will use the DP-S1 I dont think I will ever care. I just want a player to be truly portable, light weight, fit in my shirt pocket and last a day with plenty of storage space and DP-S1 offers all that.
For those who wonder how AK70 compares against DP-S1, as a stand alone DAC/DAP DP-S1 wins with no contest. However UI and features on Ak70 such us OTG to other DAPS, AK connect, wireless music download perhaps might make Ak70 a better option. But for me AK70 overheated too much for me to successively use outdoor and I find the sound to too digital and balance out simply wasn't impressive at all.
