Zuki i tried the E80 extensively. Through external speakers it literally one of the best arrangers available on the market in terms of sound. the unplugged styles are actuallly in my view the best available on ANY ARRANGER KEYBOARD . Its very intuitive to use but not very programmable in terms of sound editing and simply cant compete with your Korg Pa800 in terms of live performance and flexibility.

However....the sounds from its internal speakers was rubbish. They should not have even bother with the internal speakers if they were not going to make them sound great. I own the Korg PA1X which has incredible onboard speakers so i was truly dissappointed when i heard the E80 through its own speakers. I demoed several E80 Units at different shops in Birmingham UK and even booked an appointment with a Roland employee who acts as a roving specialist for roland products over the Westmidlands area. He could not make the internal speakers sound anywhere near as good as my Korg
