MSB or Birdland DAC?

Depends on what you want. The MSB is faster and more accurate, but the Birdland more tonally appealing and engaging. I've auditioned both on my system (mostly CJ) and for my tastes I'd take the Birdland in a second. Very nice sounding DAC.

I have the Birdland, and it is an excellent DAC, especially if you are running direct into an amplifier.

It did benenfit from damping and better powercords.
