I must not have been clear with what I was saying. The mid-bass of the M80s is fantastic right now with the Onkyo, not that more power wouldn‘t make it better. ;\) Where the mid-bass is falling short is from the LFE channel. Part of it is that I haven’t moved the sub back up front near-field since running Audyssey on the Onkyo which tamed the room down quite a bit. But I’ve still got a feeling that to get the mid-bass I want the EP500 is actually going to be to much because it goes so low. I sort of like the mid-bass running hot which has been pushing the low bass way over the top. So I still have some tweaking and probably room treatments but I’m not sure if that’s going to be enough.

So the mid-bass on the M80s if fine I’m just trying to get the LFE channel to catch up w/o everything getting to rumbly.
