Hi Dave, thanks for your reply. My apologies, I should have mentioned where I live. It is in the UK (South Wales, next to England !!) It actually came out just before the pro 76-note model, and I bought it from the main manufacturers (Synergy) in the UK. The speaker system is wicked, far far better than any professional hi-fi for instance, with a beautiful bass aspect. If you were gigging, for instance, at a venue which was not too big, you actually would not need external amplification.(honest!) Hope that answers your question. Regards & take care, Ken.
