That’s helpful. Yeah my current atcs are the scm19A’s. The passive/older version of them had terrible measurements according to Amir. But not sure if that means the actives are as bad. If so, then I’d imagine the Neumanns should be an upgrade.Depends what for. I saw on the other thread you're thinking of swapping out your active ATCs - in which case the KH420s would be in the same ballpark, and maybe even a sideways or downward move, depending on which ATCs you're using right now. With huge respect to KEF, the LS60s are domestic products heavily biased toward lifestyle convenience, and stand no chance at all of equalling either ATC or Neumann for SPLs, durability, longevity or serviceability. Apples and oranges, really.
