“these ATCs… take all in their stride, revealing a lovely cohesion throughout the frequency range. Resolution, timing and dynamics are all spot-on… factor in the built-in amplification, exotically engineered in-house drive units and the resultant exceptional sound quality, and the SCM40As emerge as something of a high-end bargain. Consider us smitten.” What Hi-Fi, March 2015.
