I am currently waiting for a pair of SCM19V2 to arrive. I will be driving them with a Norma IPA 140, which is a damn fine amp. With regard to contenders: I am selling my ML Ethos, though brilliant, because I am more accustomed to smaller boxes where the images have a better chance of being 'seen' in a virtual soundstage. I have had Spendor D7s, which were also great, but not particularly dynamic. I found that I could not live with the Harbeth 7es3 because I was too aware of cabinet resonance with some material. Sonus Faber Amator M was a very nice-sounding speaker, but my room has problems with rear-firing ports. I wish there were better videos on Youtube of the 19s. The ones with the speakers on the cabinet are anathema. Anyway, I bought the ATCs because I want smooth treble, neutral, realistic mids and tight, controlled bass. From all of my reading, I think that I have made the right choice.
I will keep you posted once they are in my system.
