A few other thoughts/experiences:

1) Hooked the L1 up to my old traditional PA... for super large gigs would use the L1 for KB and the PA for vocals and FOH.

2) With a little separation between the L1 tower and the B1 subs I did feel/hear a little stereo sep. there. While I think 2 for stereo is overkill I'd love to hear it... and be able to afford it.

3) The thing about the Bose is that vocally it shows any and all flaws... almost magnifies them and it will take a little getting use to.

4) Its LOUD as hell and the two B1's provide lots of thump... its almost too bassy really.

5) Soniclly its a little like the difference between analog and digital.

6) The fast set up and lightweightness can not be overstated.

I would love to hear from any other Tyros/L1 users.

Thanks for all PM's and thanks Gary for taking time on the phone to help me get it dialed in.
