Your thoughts about ATC loudspeakers


I’m interested in the ATC SCM-40 from their HiFi series and would like to hear from people who have owned or spent a lot of time with ATC speakers. This is a fairly new model and may be a bit of a departure from their classic sound.

At the show in Newport last weekend, I was quite taken by these speakers. I went back the next day and heard the same things that I liked about them, but a couple of red flags also went up:

Microdynamics – not sure these speakers do them well and microdynamics are critical to communicating inflection and nuance and to making music sound alive

Imaging, specifically wrt depth. Nothing much outside of the plane of the speakers, so recording venue info is not there and even instrument and vocal body may suffer a bit.

Were these shortcomings of setup or associated gear, or is this what ATC does?

Acousticfrontiers, I have had a fair share of exposure to the 40, 19 and also the SCM 20. It is true that the 19 and 20 feels lighter and quicker a bit but they somehow just do not have the midrange palpability of the 40 (due to that amazing dome mid range driver of the 40). Regarding bass, it is both ways, the 40 goes deeper and fills a bigger place more elegantly while sounding very tight and defined, where as the 19 and 20 are somewhat more lean and agile. It is going to be a matter of preference and room size IMO.
I have owned SCM-40 and have heard most others. There is nothing that the ATC cannot do. They are seriously among the absolute best speakers out there. They sound like whatever is there in the recording and what is being fed to it via the electronics in the chain. You need really good amplifiers and sky is the limit.

Look at Symphonic line amps if you are looking for the depth and width of soundstage along with a very finely nuanced and liquid sound. You can even consider an active SCM40 which in my opinion is the best thing to do.
ATC do not use the latest and greatest of the tweeters. These days we have berrylium/diamond/ribbon tweeters all doing 100khz extension. So speakers which employ those do tend to have more atmosphere but to make the whole package sound as natural is not easy and that is why most of those speakers get into the hi-fish category. ATC uses their own traditional dome tweeter which is well extended but not like 100 khz and all, hence they probably do not do those extra-terrestrial like sound. What ATC presents is a full range sound that is extremely coherent, uncolored and dynamic. When you hear it you know everything else is flawed.
