I had the E80 before part exchanging it with my G1000 for the Wersi Abacus duo pro.
The E80's onboard speakers are terrible, most of the music retailers in the UK advise purchasers about this, but if you take the outputs into a good PA or sound card on the PC then something like Logitech speakers, the E80 comes to life. It's got great sounds and styles, with plenty of depth to them
