The dac 2.0 is fantastic for right now. I am feeding my music via firewire out of a Mac Mini into a Weiss INT202 then into the Audio Note DAC via a digital cable.
I love it. The sound is still breaking in and should improve even more.
My next purchase is going to be for a pair of Audio Motr AN-E HE speakers (98 db efficiency).
I will be upgrading my wife's system with the components that I am replacing in my system. This works out pretty good for me to not get into many problems when I buy another upgrade.
