Wadia states that the Digital outputs can be disabled for sligthly better performance. I am not aware of being able to disable the inputs.
To disable the outputs, you must take the top cover off first and the nremove the bottom cover to get to the digital output board. Set dip switches 1, 3, 5 and 7 to the open position. Once you do this you have disabled all of the outputs and it doesn't matter if dip switches 2, 4, 6 and 8 are open or closed.
To set a dip switch to the open position, push an individual dip switch down towards the number on the switch housing. Another way to realize this is to realize that the player comes pre-set with switches 1,3,5 and 7 in the closed position. Therefore, set these switches of a new player to the opposite position.
I haven't done an A/B since I had these disabled previous to purchase.
