It (the MSB) is a true transport that deals with the jitter just like the cd transport. Now you have ipod docks like the wadia 170 all it does is bypass the ipods dac. I would use the wadia 170 dock as background music. Iam not knocking the wadia but its not a ipod transport.Again, I addressed this in another forum, the Wadia iTransport bypasses the DAC and you can purchase DAC's that handle jitter. So your knock on the Wadia it totally unfounded.
I don't know anything about the MSB, does it bypass the internal DAC of the iPod?
