Have you tried the Coppers with Sony Hybrids? I found these to be best for getting a deeper seal and more bass.
I'd say the IE8 has the most powerful and intrusive bass of the three. It also isolates the least. The Atrio MG7 has a more visceral sub-bass rumble, but has less mid-bass compared to the IE8 (with the dial on full). The Copper with sony hybrids sits somewhere between the two I'd say with more of a balance between mid and sub-bass. I wouldn't describe it as lacking bass.
It might be worth considering the Westone 3 too if you like mid-bass punch over sub-bass rumble. I don't know about the Monster MDs just yet as I'm awaiting a replacement pair.
