I have discovered the same thing, that playing keyboards in stereo on stage makes a huge difference in your sound, particularly if you rely on a good acoustic piano, B3/Leslie, or chorused EP sound. The leslie effect is particularly good in stereo (I use a Nord Stage). A few years ago I started using 2 JBL Eon 10s on stage in a rock band scenario, because I wasn't satisfied with the sound I was getting with a single amplifier. At first thinking that they might be both bass-challenged and underpowered, I was pleasantly surprised to find they were PLENTY LOUD and have surprisingly decent bass response for such small speakers. I've been very happy with the sound, and the fact that they are so compact and light are a bonus.

I also have one Bose L1 Compact. I've tried this on stage and have had the same problem that Tony described - acoustic piano through it leaves a lot to be desired. I'm glad to learn that Tony has had much better results using 2 of them in stereo, and may eventually go to this setup myself. They do not, however, have the power reserve that the Eons have. Volume-wise, I could not quite keep up with the rest of the band when using only one, and I suspect that two wouldn't improve that aspect appreciably.

Thanks for sharing your info on this.
