I just replaced my Quad 12L monitors with a pair of Aurum Cantus Leisure 2SE's from Kellsie Audio Video. I bought them used here on A-gon. The Aurum Cantus, IMHO, are definitely a superior speaker, in every respect. The Leisure 2SE's are a serious speaker. Bass is deeper and more realistic. I bought them for the ribbon tweeter to achieve better extension and clarity, and in that regard, they delivered superbly. But I did not expect the bass they reproduce. Mid range is excellent, imaging is excellent - overall they sound much bigger and musical. After listening to the Aurum Cantus, the Quads just sound flat and un-involving. In addition to all of that, the finish is first rate, the matching stands are beautiful. These speakers are real show-stoppers.
