Sloped baffle

Bifwynne, Dunlavy and Meadowlark are gone. I'm not sure if the newer Quads qualify. Some Thiels are, for the time being...the future looks glum. I have doubts that the newer Ohms qualify. I'd hazard a guess that the HHR ExoticSpeakers do, but I haven't seen verification. I would say the same for the German Physiks and similar Huffs, at least for the models that use their DDD drivers exclusively, I have doubts that their full range models qualify. FWIW, I have confidence that the others still do.

Bifwynne, if you're in contact with DEQX, if you wouldn't mind, perhaps you might ask them why their system approach includes analog conversion rather than keeping the whole stream in the digital domain?

Bifwynne,
unfortunately all of the companies stated in Unsound's post do NOT still make time-coherent speakers. (John) Dunlavy quit making his speakers long time back & I believe that he, unfortunately, is not with us anymore (correct me if I'm wrong but that's what I remember reading in one thread).
And, Meadowlark also does not make speakers anymore. Unfortunately there was something very unsavoury that went down w/ Pat McGinty (owner/designer of Meadowlark), his company & the location where he was making speakers.
Audiomachina also does not make time-coherent speakers anymore.
I was reading an old Meadowlark Osprey speaker review on enjoythemusic.com

The Meadowlark Mantra

Three design principles underlie every Meadowlark loudspeaker: time coherence, first-order crossovers and transmission line bass............

McGinty argues articulately on his web site that time coherence is essential to long-term musical satisfaction and avoidance of listener fatigue.....

Bombaywalla, unless this:

is out of date, I think they still are.

Bifwynne, Unsound,
found this website of Meadowlark/Pat McGinty showing off all the Meadowlark speakers. I loved the looks of the Meadowlarks due to their superb wood finishes - always such a pleasure to see!
