darby, I'm thinking of buying. I would definitely need the a60 adapters and I need to unload my ck69's first.
At one point I owned my ck8s and a pair of ck68's... although I loved the sound of the ck68s,
the fact that they didn't work with my 480s because of the side pin
like the mk46 active cables and obviously my 451s (smaller diameter)
was the reason I sold them since I don't need two pairs of shotguns.
In your case I don't know why you would would want to trade off, other than the difference in price.
