Yeah, the one I posted before didn't had an headphones plug...Indeed it has the burr brown chip like the Dangerous Music Source and other high end gear.
Another company you might want to check is:
Oh ok.. well a headphone output is a must..
Regarding burr brown it is good to have a good DAC chip but it is only one part of the DAC so it does not really say much about the DAC itself more then that the desiner obviously know that most high end gear use Burr Brown.. but this chip only cost a few dollars so.. it is not like it is some super expensive exclusive thing..
I am aware of Fiio, it is the most well known and popular headphone amps and DACs, it is popular for the more consumer market also, so I am gladely trying to look deeper into the market to find these unkown gold corns which people including myself is hard to find...
The sony is for sure an alternative, but I am also sure there is a similar product without the sony logo that is less expensive.. The sony price is ok if the sound is really good and would satisfy my needs more long term..
