Was the LSX an open baffle design? What is your take on the ranking of speakers?
Yes, the ones I heard at RMAF, dubbed the LSX, were an OB design.
I haven’t heard the NX-Otica/NX-Treme’s, so I can’t really comment on those or the monitors
I have heard many of the others and have to agree with the consensus about scale on them. “Big” music sounds better on the LS 9’s and to a lesser extent the LS 6’s, but it’s tough to do Intimate performances as well. It sounds very good, but not the right scale of soundstage.
The midrange purity of the Super 7’s is hard to beat. I LOVE these speakers even though my room acoustics are problematic. I doubt I will ever feel the need for a different speaker (unless I hit the Lottery, in which case

)
The Super V’s are a great speaker that are missing that speed in the Mids that the Super 7’s have, but are incredibly dynamic and play a well with a variety of music styles.
The first speakers I heard were back in the AV 123 days at a GTG and I really liked the X-Statiks, but it was in a very unfamiliar setting.
The LS X did so many things incredibly well. Very impressed with pretty much everything I heard.
I have never heard the Line Force. I hope that somebody recreates them with the New Drivers. Slightly different, but may be better if some of the comments I’ve seen about the Radian LM10n are correct. Not sure if they can be paired with the GR Research Neo 3 from a sensitivity standpoint, and they would be very pricey, but……..sigh, I can dream.
