IME I really wouldn't worry about the directionality of Monster ICs. I have a bunch of Monster THX I100 analog ICs and Digital coax cables and when I mixed up the directions I heard no difference in sound quality. Gear used at the time was Emotiva ERC-1 CDP, Marantz CD-5003 CDP, then a McCormack DAC-1 connected to a McCormack TLC-1 preamp.
On a different note when I had a pair of Tice Audio speaker wire that had arrows showing the direction of the signal flow but the instructions said the proper direction is the one that sounds good to you.
