I've listened to the demos and to the G70 live... I think it is not possible to make a comparison, because MP3 compression wastes every sound quality (that's why I don't like it at, all unless you really need low space occupation)...
in the demos every frequency over 5kHz seems cut!!!

so in my opinion: try to listen it live and then make your personal opinion (of course it can be negative and different from mine...that's personal taste)

bye...
(p.s. IMHO the sound of a live good drummer will always be better!!!)
