Let us know which way you go, Scott. If you still feel unsure which way to go, you can always call Outlaw and chat with the sales crew - they have likely worked with other RTi10 owners and may be able to give you some feedback in relation to your speakers and room size that could take some of the uncertainty away. There's also the 30-day trial period, allowing you to return the 7125 and order M2200's if you feel the need to, although I suspect that once you get a 7125 in place and running you'll be happy right there.
