To a person who has GR07, IE8 and FX700, is it worth it to purchase the EX1000?
Sources are iphone, ipod, E11 and A10 with ALAC files. Music choices are everything but country. Also, I'd rather not use the amps and I do love the sounds of each earphone for their differences.
I would say no.
You would be better of saving money for customs;
Why waste more cash on another universal when you have a pair of customs if you save a little more?
The Sony iems are not cheap; they cost around Singapore $680 approximately (offer price from Sony shop) elsewhere, I heard they cost close to $700 to nearly $1000 (Singapore dollars)
And they offer little, if any, marked sound improvement over the other top tier universals you own, hence it would be more of a side grade in terms of sound.
However, this is just my view;
If you really want to buy, go and demo out a pair before making a decision.
And buy them online, preferably 2nd hand to save $$$
