Still have two sets of CM5’s in two bedrooms. My son has inherited my CM6’s which I had stand mounted and supplemented by an M&K sub. Replaced those with Aerial Acoustics 8b towers. Aerial was founded by Michael Kelly, formerly of ADS, who still operates Aerial.
Fun aside - had dealer who sold me the Aerial 8b’s come to the house and try to sell me a McIntosh bookshelf to replace the ADS CM5’s. His speakers were at least three times the size of the ADS. He walked out shaking his head. Couldn’t believe the little CM 5’s had deeper, tighter, bass and we’re clearer across the spectrum compared to the larger McIntosh speakers. I wasn’t surprised. It’s why I still have them.
Only very small speakers I’ve heard that were somewhat comparable to the CM5’s were the ATC SCM 7’s. The ATC’s mid and high frequency response was better - clearer and more extended highs. But they do not deliver the low end of the CM5’s.
