Thus by attacking either (1) or (2) you do precisely nothing to

It's really quite simple, Jim. If one makes the statement "all cables
sound the same" as Stewart did, you cannot then say "some cables sound
different". This is basic formal logic, as I'm sure you are aware.
E.g.. "All Aussies are Australians" is not compatible with "Some
Aussies are not Australians".
