To be honest, I think the dual out stereo jacks will only appeal to the true audiophiles. My feeling is that this player will have an above average price tag, and maybe a little too complicated for the average Joe to use or want. I'm not sure how common HD radio is in China, but if I were teclast, I would get rid of the dual jacks/wolfsons, and throw some HD radio capability in there. Look at the new Zune HD. The thing will be unbelievable successful for just that reason, HD radio. I think that the Dual jacks should be an option for those truly interested, but I think it may cause a lot more problems than it is actually worth. Put something in there that will appeal to the masses. We have not seen one Chinese company try to iimitate any of the American designed mp3/4 players, and until then, they will not see the success of the American companys like Apple, Microsoft, and Sandisk. When are they going to realize that people want reliability, and usability more than anything? If teclast was smart, they would not worry so much about the super crazy amazing hd quality dual jack audio. Keep it simple and reliable. I think this player is defeating the purpose of pretty much any consumer products.
I think their intent is to reach out to a niche audience, as WELL as mp3/pmp customers at large. If you search the various dap forums, there's definitely a market for players with line out - but there's precious few that can achieve it in the current generation of players. When I was searching for one - the Sansa Fuze is the only one that stood out, and it can really only do line out via a dock. Though some people have modded the docks into basic cables - and started selling their own.
It's useful for audiophiles who connect to portable amps, and also for those that just want to play their daps on their stereo - with better fidelity. I'm already intrigued to buy one as a replacement or complement for my Fuze. The fact that it wouldn't require a special cable or dock is a bonus.
But if it can do HD TV Out or has a high resolution screen - then it's a MUST BUY for me, imo.
