Yes, I love having two. I like to hear myself in stereo. Many of the effects and voices were designed to be heard in stereo.
And, I always have a backup with me just in case one would fail.
Before I got the two Compacts, I had two of the big L1s, with thwo subs. I never in three years had an occasion where I really needed that much amplification, although it certainly sounded fine.
I got a Compact and liked it, so I got a second one. After a year or so I sold both the L1s because they weren't needed for the venues where I play.
I can comfortably handle a couple hundred people. If I have need for more, I can always borrow back one or both the L1s I sold!
