@stfoth - "Probably going to go with monitors.......looks like the monitors use different tweeters and have different specs from the Double-Impact surround speakers. Curious whether anyone has considered the differences or considered the surrounds as main monitors with tubes."
Good question! I own the Impact Monitors but didn’t consider the DI surrounds. Looks like they have a higher sensitivity. That may be helpful if you want to run lower powered amps. I can tell you the Impact Monitors have been getting rave "first impression" reviews from RMAF. (Go to the Impact Monitor thread to see my compilation of the reviews https://forum.audiogon.com/discussions/tekton-impact-monitors/post?postid=1470434#1470434) I use a REL powered sub with mine and am very satisfied with the lower mids and bass. At their price, the Impact Monitors are very hard to beat.
