Ecce, ATC SCM 7 strong in Mid , weak in high extention
It requires very high current amplifer to push the bass unit(the bass unit magnetic is even larger than the diameter of the woofer bass unit!) . So i dont think your NAD can drive it well. That why people suggest use Active ACT speaker in some cases.
Personally using Dyna 1.3se with Sim I-5 have good result except power. However , Dyna also need high quality and current to sound their best . I did part my Dyna with a Rotel 1090 amplifier with a poor result.
Spendor may be easily to part with amplifier and have a typical British sound character , which is warm and good image. I think NAD is not bad with Spendor.
