Your Yamaha amp should already be optimized for a standard "line" level which the Touch provides (use one of the "TAPE" or "AUX" inputs, NOT the PHONO!). I would say don't add anything between the Touch and your 720. I would use the 720's volume control to get the best setting - use the technique mlsstl described - set the Touch to max output, play a song which is in the "softer" range, and set the volume control on your Yamaha to as loud as you think you'd ever want for that listening area. After that, go ahead and use the Touch's "digital" volume control for your day-to-day volume changes. I would leave your "mute" button OFF, and then it can be handy for it's intended purpose - to easily mute or lower the volume for a brief period (e.g., answering the phone).
