Hello McDuck,
I see you are at it again.
What makes you think I do not have the Linkwitz preamp and modified capsules? I pointed to Linkwitz!
I do have the Linkwitz preamp (as well as others) and I have pro audio gear as well. Also I have both modified and unmodified capsules. None of that stops me from trying to learn if something else exists that might be useful to me. Now that you know would it have changed your question?
If you choose to respond again with an, "I didn't know," type answer, that is exactly the point.
