Graham is absolutely right on the money. And, as stated above by our elder and very learned members Bernie and John, the audience likely does not perceive a difference.

While stereo will surely sound great to the entertainer, the guy behind the keyboard, this is mainly because he or she is living in a surround sound environment - the audience is not. That said, heavily stereo sampled voices will, obviously, sound better. They will sound full and rich, while those that are mono sampled tend to sound thin and somewhat weak, but that can easily be corrected with some EQs and tuning.

When I went from stereo to mono, not a single audience or audience member noticed. They likely didn't notice any difference at all. And, I was loading less on the Rock And Roller cart, my back noticed that difference, and I sold the second Bose L1 Compact for a couple hundred bucks less than I paid for it. The primary Bose L1 still sits in my office, hoping my aging body miraculously reverses the aging and disease progression and I go back to playing once again - NOT!

This dead horse has really taken a beating and the same folks seem to continue to bring it up and provide the same comments every year - AMAZING!

All the best,

Gary
