@PaganDL Thank you my friend! I just get an answer from Cowon France (Sorry, i'm French.. ) And they just said to me : (Translation) "The body of Plenue D/D2 is made of high quality reinforced Aluminium processed with a CNC machine" So you're totally right, Thank you! As for the sound, i came across this D2 review that talked about the PD (1st gen) : The man said at 2mn : "The D (1st gen) did not output as much power as it really should, in fact, there wasn't much more power than a typical iPhone 4". Does that mean that i'll get no improved sound from the PD compared to an iPhone 4? That will be my first DAP ever, sorry for my newb questions.. I wish you a great day!!
