I have found the L2 to be convenient and it improves the clarity of my streaming. I was able to run fiber optic from my router to the L2 (35 feet) and fiber optic into the X1. I no longer need an EtherRegen. I connected my Apple TV module to the L2. This is where the improvements in audio quality is must noticeable. With the X1 streaming signal through the L2, there is an improvement in clarity but it’s subtle at best. The investment feels worthwhile and I would recommend it.
