Hi guys - just to add my thoughts to this. I have recently bought the Lucas nano 600 and I have to say, so far, I am very impressed! I had been using the Yamaha stage pas 600i, which is also a great system. For the type of bookings I mainly do (ballroom dancing etc using keyboards - Korg pa600 and tyros 4) I think the lucas nano 600 gave a really nice, high quality 'full' sound. This is probably because of the sub (the stage pas 600i is just the 2 top cabinets). Overall, I enjoyed the sound of my keyboards better through the nano 600. It is also very compact and the little top speakers very neat and don't distract visually on stage the way I find bigger top speakers can. Not sure how the nano 600 would be at a 'loud' party type booking - but I have some coming up, so we will see! Just out of interest, I have had the Bose L1 in the past (all models except the compact). My thoughts were that they were great quality, but I like playing in stereo and it seemed a lot of Bose pieces to take in to the booking to achieve this.
