Thank you all. After much consideration I have decided to add a power amplifier for bi-amping to drive the ATC SCM 7. I was using the Roksan K3 integrated amplifier and will add the Roksan K3 power amplifier
Very interesting read so far. Perhaps the lack of bass on the ATC could be due to a less than powerful amplifier. Don't forget the sensitivity is only 84db and it requires something more powerful than the 75 watts it suggests to drive them.
I have a pair of ATC SCM 7. I am looking very hard at the Cambridge CXA81. My question is whether the Cambridge can drive the speakers. Any help is very much appreciated. Thank you.
