I have not heard those EMP's so cannot comment. However, if you could tell us what you do not like about the EMP's we may be able to better help you.
Just saying you didn't like them is problematic because several people have them and do like them.
Is there a particular instrument or song that really disappoints you?
Are there other places where you like the sound?
What is your "reference" for not liking the sound of them? - what speakers have you listened to in the past that you liked?
It may be that your expectations do not fit your budget.
Also, two comments:
1) Unless you have to, don't sell your EMP's until you get the new speakers so you can compare them. Otherwise you can convince your self of anything, or conversely second guess your decision - but you'll never know for certain how they compare unles you have both in your room to compare.
2) Why the Intimus 5 series instead of the new Verus series (Forte or Grand)? Not all updates are upgrades, but it seems like Aperion has invested a good bit of effort into their new lines.
