ATC SCM20A Pro

For whom? And Conclusion

Contents

Good question. Of course for the audio engineer who works with vocals, classical, acoustic and jazz. And of course for all types of music, but we do think it excels in the genres mentioned above. These monitors are an indispensable tool; if the mix sounds good on the SCM20A, then it will sound good everywhere. It seems to be a slightly more forgiving alternative to the no longer available Yamaha NS10. In the studio, an A/B comparison with a full-range and midfield monitor is necessary.

For those looking for the ultimate desktop speaker, this ATC is definitely an option. Place them about 1 metre apart, connect a good DAC with volume control and you won’t want to leave your desk.

For the living room, the SCM20A has a surprisingly wide range for a nearfield monitor. The sound image remains intact at a distance of a few metres, although we do miss the bass. These monitors can function perfectly in a not too large room. An additional subwoofer would be the solution if you want more bass. If you are brand loyal and stick with ATC, these will come at a hefty price tag. However, subwoofers are also available from other good studio brands (such as Genelec and Dynaudio).

Conclusion

This review practically wrote itself. We can vividly remember the moments of the listening sessions with these ATC SCM20A speakers. And that is what makes music beautiful: discovering, enjoying and sharing experiences. These ATC monitors are the A-brand tools in the studio, but certainly feel at home on your desk, in your living room or listening room. Depending on the size of your room, you may need to add a subwoofer because the bass punch of these monitors alone may not be enough. We have more than often not missed the bass a bit and found the coherence of the SCM20A impressive, enticing and convincing. It is as if these monitors allow us to hear how the recording should sound according to the musicians, the audio technicians and the conductor in the studio's control room. Getting the midrange right is often seen as a complex and tedious job by sound engineers. We think they must not have worked with the SCM20A, because this monitor simply loves the midrange. And so do we. Alpha Approved!

  1. Hi Yung,

    I have been following you guys for some time and I would just like to say, thank you for your work here and sharing your reviews and comparisons. You are just about the only group who actually compares like products in a systematic manner. As a former HiFi dealer, we used to take great care in not only comparing products in the evaluation for what to carry in the store but we went to great lengths to find proper combinations of components etc. It is a sad situation that this is just simply not done for the most part in the majority of the market. Publications, be it in print or on-line nor dealers take the time for the most part. So, thank you for that effort. It takes time and dedicated effort and it is very much appreciated.

    I am curious how you would compare the ATC SCM 20A to that of the equivalent monitor in the PSI line? Also, in the ATC passive line up, how would you characterize the differences between the SCM 12 Pro and SCM 20 Pro?

    Thanks, again….Best regards….John
