Greg - The SMS-1 is an excellent unit, and will help achieve a flat frequency response. However... it is going to be around $500 street price - so if the trim settings can "get you there" in regards to your response curve, the monsy may be spent better elsewhere.

Oh - and all the stuff arrived while I was home to let the dog out. There are now twin EP-600's hooked up. I am back at the office for a west coast conference call (on a FRIDAY ... grrrrrrrr) ... but there will be abuse ... err ... tests done this weekend.
