So I drove out to West Virginia to pick up the 1a pair. Not quite in service yet as I'm waiting on covers to be finished for protection from the kitties so slumming it with the Left channel on my scrappy looking Time Window 1 and using the DCM Cinemascape as the right channel temporarily until I have the new 1a set ready to go.
They are in pretty nice shape, original Brown fabric is still on them with no tears so definitely happy with the condition. Seller demo'd them upon pickup and they definitely are in good working order and can put out some sound.
Will drop in a final update with impressions on the sound of the 1a set vs the original design in my space.
Thanks again to all who chimed in!
