We tested them head-to-head in our May 2007 issue, along with the ATC SCM19s and Wilson Benesch Square Ones. Uniquely for a Group Test of this type, all four sets of speakers scored five-stars - all are excellent but in different ways. We felt the Wilson Benesch pair had the edge on all of them, but here are the For/Against and Verdicts for the whole lot:
For - Dynamic, neutrality and loudness capability; rugged build
Against - Ruthless nature won't please all
Verdict -Want to hear what they heard in the stuidio? These ATCs are the closest you'll get in this test.
For - A beautifully balanced sound that works well with all types of music; excellent build and great aesthetics.
Against - They're not a tonally neutral as some.
Verdict - The oldest speakers in this test continue to be some of the best: the 805S remain very hard to beat.
Dali Mentor 2
For - Fine treble; informative, full-bodied and lively sound.
Against - Don't like very high volume levels; twin tweeter arrangement spoils proportions
Verdict - The Mentor 2s put musical enjoyment before all else; not for party volumes, though.
Wilson Benesch Square One
For - Speed, insight and dynamics are breathtakingly good; works well in a close-to-the-wall position; compact size.
Against - Finish on our review sample could be better (EDIT - WB has since addressed this)
Verdict - The Square Ones are fabulous, delivering true high-end Wilson Benesch sound for very sensible money.
