Description
ATC SCM40A.
Proper active loudspeakers have the crossover arranged at ‘line level’ in from of the power amplifiers and the power amps connected directly to the drivers. The SCM40A is a proper three way active speaker and has the audio signal fed to the XLR socket on the back of the loudspeakers
ATC make suitable preamplifiers but we also know that Naim and Linn ones are extremely well suited to these duties too. This includes the linn DS products and Naim NAC-N 172.

“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.
