The reason I'm lookin' is because durring todays broadcast I noted some white noise in my signal when connecting the output of my laptop to the Tape/CD input of my mixer.... it got better when I connected it later to a Line Level input and turned the channel gain down....but, my experience when I turn the gain down is I lose quality when hooked into the PA system... nevermind thru the headphones...
I think other than color being different according to what I can read the Red one offers better D/A converters.... and a lot of software... but, I don't give a hoot about the software package just that the sound floor is lower...
