Question
Great thread. I have just read all 38 pages and feel like I need to take a nap! Thank you Skylab! Your dedication is incredible.
I started off the thread wanting a Hornet, then a Headphonia, then a Tomahawk and now a Porta Corda Mrk III... and I feel that may change to a Corda Move in a few days time.

One point I'm a bit confused on, that I would like clarified for the benefit of newbies such as I.
What exactly is the benefit in buying a DAC amp vs a normal amp?
For example, when using a laptop, would the DAC amps that use USB such as the Bithead, Corda Move or Headphonia be preferred over a non DAC amp that uses the headphone jack such as an RSA Hornet or Tomahawk?
Is there much of a difference? Or is the advantage solely in that you can power the amp from the USB?
I'm just a tad bit confused here.
I'm trying to decide what to buy for my Beyer DT770/80, that I plan to use with my macbook and on the road with my ipod.
Thanks.
