Hi Jim
I got the speaker stands so you can use it in stereo and it looks and sounds great. I will be using it in a couple of weeks at a booking that needs a bit more volume so I'll be taking the stage pas 600i and seeing how it compares. So far, though, I prefer the nano 600 - it seems a fuller sound to me - presumably because of the sub. I'll post more the next couple of weeks once I've given the system a few more outings! By the way, I am currently playing Yamaha tyros 4 and Korg pa600 through it.
