If you check it's online presentation on ebay and penonaudio you can read things like:
First portable player can power well with full size headphones & all type earphones
Micro Dynamic Class A power amplifier
New HiFi sound quality
The sound quality of S6 comes from Hisoundaudio’s 20 years hi end home audio design experiences
but
there is nothing to be found about this "20year old hifi company" on net
their website doesn't work for.... did it ever work?
they present all their products like hifi, class A, audiophile, etc. even their cheapest ones
their expensive Studio players use cheap electronic (

I have owned Studio 3rd anniversary for some time and it was a nice player. Premium look, sturdy, long battery life, very revealing and analytical. On the other hand it was buggy, sound wasn't much fun, it lacked "musicality", warmth and naturality to my ears, navigation was pain. I didn't enjoy music from it anymore and sold it. I would like to buy myself a new player, but there is none for me on market now. I'm looking for player which sound blows me away but it wont cost over 500 bucks because of functions i wont use like all those X7, Asterns and Sony ZX1,2 have. Studio S6 looks again simplistic as it's predecessors and i like it VERY much. But will it deliver that mind blowing sound it promises or is it just an cheap product with HIFI sticker on it?
Im looking for some unbiased experience from owners.
Btw.. can we get some pictures? All i could find was some small resolution pictures on penonaudio, but i couldnt tell much from it.
