Haven't heard E07,so I can't comment on that. I can tell you that X3 and X5 have different sound signatures, so if you really liked the X3 it might be better to buy that instead of X1, X3 II, or X5. I've been thinking of selling my X3,so if you are interested in that it's available, in near mint shape, and will be lower priced than a brand new one.
Thanks for your suggestions and offer. Do note that I stay in Delhi, India and do PM your price and whether you can ship it here.
Thanks & cheers
