Hi Ed,

You can easily dismiss the theory and take the quick step up to the
bar of experience - your own (who better?).

Does it match on the bands you prefer? Changing things will not
improve what is already acceptable.

Are you worried about what you cannot see? Loss? Ah! Then we
migrate into the world of the skeptical and theoretical where there
are probably questions you cannot answer - which questions require
data to give you specific solutions.

You ask one of these questions (by inference) yourself: 400 Ohms or
600 Ohms? You don't know, but it "could" make a difference. Here,
the "could" is a question of degree. Yes, on paper it is significant,
but in practice the listener of your signal would never note any
improvement if you invested effort, equipment, and time in finding the
answer and implementing a change to correct the "problem."

Let's examine what is significant. Would you like to eliminate 1dB of
loss (make that 1dB available to the listener)? Do you know what 1dB
looks like on an S-Meter? I would suppose so: about the thickness of
the needle. Would you invest $1000 to do that? Which is significant:
1. 1dB;
2. $1000.

Feel free to adjust both numbers to more closely conform to your
situation and expectations and respond in that context.
