upgrade of lamm/wilson

If you must use the Lamm I guess you could by Passive ATC's .

SCM100's will fit the bill and outperform even the best Wilson (yes the X2) through the midrange and highs.

Powered ATC's will only open the margin farther from the competition. And you can sell the Lamms

What kind of things are you wanting an upgrade on? Going from the 7s to a horn or Kharma will give you an entirely different sound. That's for sure.

Any updates?

Check out Wilson Benesch Chimeras.I am very pleased with them.

Hi Rumney
which speaker you finally decide on?
your room is quite large, are you sure ML2.1 will work with the Maxx2 well?
