Possible that I might have some/partial of the details you are asking but can you please post a picture of the monitors you are referring to? Thanks. I have a pair of Dyna 10's but want to be sure of the ones you are looking at. What are the KA-10? Can you post the link to those? I always save a link of the speakers because the pictures rapidly change from the Omega front page or gallery and, later, they are hard (for me) to find again.
Yes, sometimes, there are "every now and then" offerings as far as I can tell.
On the Dyna 10's they are unique to the line. Hope to hear from you here and sorry you had to wait for a reply. I'm a customer and not too techincal but want to see what's up, too.
