@rsf507 Fair point. You're right, a bit of digging and seems those Ktema speakers have been around for 12 years, one of FS' last creations. Thank you for correcting me. I think it's the first time I've come across them. Agree they were wonderful, and there's no doubt the Air Tight electronics contributed to it.
I can't really speak to why I like those vs what I have previously heard from Sonus Faber. It's obvious that the engineering in the cabinet is quite different from the Ktema speakers. I did enjoy both rooms, but as noted, I didn't cover either of them as the ones that stood out the most. The musicality and tone of that AXISS room was really quite good, however. There were certainly a lot of "quite good" rooms. But again, everyone has personal preferences. No wrong or right in this one.
