I keep thinking about how adding a set of cables into the signal chain should not be better, different yes, but being better is questionable.
What if you could internally hard wire those connections, that would be the ultimate connection, and shortest/purest signal path. You would also eliminate four external connectors. This makes the short stock jumpers the next best thing from an EE design perspective.
After looking at an internal picture of the MA8950, this task would not be easy or safe for most of us.
