Mini Review
I now have some hours playing with my new amp3 pro2, version 5.42.
Using the hisound earphones, and the koss porta pro or grado sr60.
1-
The machine: great quality... it's small, but very well built. I think it's a beatiful gadget

2-
The earphones: they are very good, they do look cheap but sound very smooth. I use it with my ibasso D4, and ipod classic, via qables reference lod, and the sound was clear, with the right amount of bass, and treble....
3-
Menu interface: the thing a like less... it seams like an mp3 from other century....the ebook??? What for?
To be honest I don't know if my amp is in normal playmode??? (What is the symbol for that?)
And As I read with the new firmware... when I turn off the player while listening to some song then when I start it again it would go to the song I was playing!? But mine don't!
The time to start up is 1 or two minutes with an 8gb sdhc card...

Sound quality: that's the reason!!! It very very good!!! As far as you use inear phones.... or in canal phones, the ones that came with the amp3 are very good.... but the etymotic 6i go very well to... With "normal" phones (and I use only koss porta pro and grado sr60) there's no power to drive then!!!

The sound is weak... and if you put it maximum level (31) the hiss will be very bad for yours ears.
The sound is clear, crystal clear, smooth, full, very balanced.... the bass is there, the treble clean...

Conclusion: If you want an small player with a great sound for in ear or in canal phones, and to listen not so loud (metal lovers stay way...), this is a great one, and with the price (I pay 120 euros) ....

If you want to drive normal headphones... I think you should buy another rig... the ibasso d4 as an amp, and an ipod or cowon or iriver or sony player.
Regards
PS- Please clarify me! What symbol should I saw in my amp3 in normal mode play? A small white square with an reverse arrow inside?
