Though you guys might like to know. Just picked up a Mackie "Big Knob" which is a small desktop studio command system. I was using the i3 Audio unit which was okay, but had a pretty cheap volume control that always worked like an old am radio volume control.
Just finished up a long day and the Mackie unit performed beautifully. (going to Genelec 1030a's)
Hope this helps some of you.
Here is a link to the product and NO I don't work for Mackie.

BTW - Bayview Audio has them in stock.
