[iTunes] Slightly off topic: Preferences, Sound choice help

[Scott Stamper]

All,

I use iTunes to run my main music rig and secondary setups as a  
hardwired network, as well as wireless, depending on which room of the  
house I'm in.

I have several USB sources to output. Once is for my headphone amp,  
another for the main DAC in my main listening room.

This means I have to switch the output choice in my System Preferences  
under "Sound" whenever I want to use my headphones vs my DAC and tube  
amp for my main speakers, for example.

I've been unsuccessfully trying to figure out how to put the Sound  
from System Preferences in my Dock, or otherwise access that area  
without going thru the requisite several layer drill down. I don't  
know how to setup up an Applescript that might be a potential solution.

I'm open to any and all ideas about how I can switch Sound output  
choices more quickly and conveniently.

Ideas?

Scott
