The ATC sound is the most natural I've ever heard. I've lusted after it for many years, but finally now able to afford to build a new system based around it.
Just need the right DAC/pre, then moving this to the Done For Now category.
I don't think you'll go wrong with either one cause they're effectively the same speaker - the SCM19 may be even better choice for home listening, and being able to hear it personally via demo eliminates the unknown factor of the SCM20SLs in your actual system.
Clarity at low levels is absolutely not an issue with the ATCs -- the only difference is the SPL. I listened at almost concert levels one night and the system just kept cranking, with no change in tonal balance or details, just volume. It was pretty awesome before I reached for the remote for the sake of my neighbors!
Thanks! I did audition the SCM11, SCM19 and SCM40s. The SCM11 are just unbelievable for what they can do, but I wanted the SL driver for higher SPL and a bit more bass. The SCM40s midrange driver is unreal for clarity but I found to my surprise the integration across the tweeter and bass driver was not as coherent as the 2-ways. Maybe they were also not setup quite right when I heard them, as I should imagine correct seating height is quite critical to get the 3-way to work. I went for the SCM20SL as they are about the same price as the SCM19 but have a better/heavier cabinet and also come with a more expensive SEAS tweeter instead of the VIFA in the domestic entry levels. Also saw an internal shot of the SCM19's crossover and wasn't thrilled to see Bennic caps in there. The SCM20SLs come with the ATC marked Ansar caps. I can upgrade these myself in the future, but all those things considered I went for the Pro model. They are pretty much the same design though, apart from veneer, cabinet weight, tweeter and brand of caps.
Musically, I like a lot of electronica and female singer- songwriter stuff but the ATCs play any genre without prejudice. I listen at high SPLs until late evening cause i live in an apartment block. My neighbor downstairs must hate me! Room is about 15 x 12 -- pretty small (another reason I didn't go for the SCM40) but I got a big old rug on the floor and some GIK acoustic panels that I've not put up yet.
Thanks very much. I'll post a pic in a couple weeks once I've chosen a DAC. And gotten more furniture! I considered the CDA2 but don't really need CD playback and am looking at the NAD M51, Benchmark 2 and Mytek 192, which all offer USB connectivity.
