Hello Dear Head-FIers.
I have the CLAS and I guess I like it for portable use.. but it does not work with Mac's and I need a DAC to go around with my Macbook Air.
I just got a Apogee ONE from apple, and I am curious can I use an external amp with it and use it just as a DAC?
I need to drive my HD800's since thats what I use mobile. Anyone tried these?
PS: Can you run an external amp with a uDAC?

Are you planning on using a portable amplifier with the Apogee ONE? If so, it will work fine as a DAC, though you may need to turn the volume level on the Apogee ONE to -12 db or so to avoid overloading the input on the portable amp.  If you are planning on using a home amplifier with the ONE, it may cause a ground loop (characterized by a buzzing sound) depending on the susceptibility to ground loops of the amp.  The Meier Audio Corda Arietta I have worked well with the ONE, using a good quality Mini to RCA cable, and I have a feeling other Meier home headphone amps will work as well, as does their portable amps, like the Stepdance series, and Move series, among others.

You'll still technically be using two gain-stages, but it sounds great with a lot of amps.
