So I received the following DAPs: Benjie S5, C1, K9, Idealist S1813, ONN X5. I will post some impression on them for
@CoiL
ONN X5
Sound is very good but an easy pass due to it's bad firmware and difficult navigation, not to mention updating the player is nearly impossible to accomplish.
Idealist S1813
Honestly this player is extremely good but for some reason the screen just ruins it for me. The animations are so wacky and the transitions in the menus feel so primitive. This player reminds me of dial-up internet.
Benjie K9/C1
I'll include both of these in one impression because essentially they are the same player sound wise. The difference between these two is the build quality and screen, the C1 has a plastic body and feels extremely cheap, I would not recommend it, while the K9 has a metal back-plate while the front is completely glass. The K9 is heavy, to give you an idea of how heavy it is, the K9 and an 80GB iPod classic feel the same (in terms of weight). If the K9 had a dedicated back button it would be perfect because the controls can be hard to memorize.
Benjie S5
Tiny but packs a punch. The S5 is essentially a beefier Sansa Clip. The firmware is very similar except that the S5 comes with Folder View, in terms of sound the S5 blows away my Clip Plus. The build quality is very impressive, I really like how it combines the touch and solid buttons. This player has a back button, I can't stress enough how much easier it is to navigate through menus when you have a back button. The only drawback for me is that the touch keys are not backlit so using it at night is kind of hard, but since the buttons are nicely layed out its only a matter of time before I can memorize the positions. If you do get the S5 I recommend the Xduoo XQ10 amp, it turns the S5 into a monster portable rig.
I hope these impressions help you make a decision
