Greg and Ken.

It really depend upon the relative input and output impedance of one 
unit to the next.  That is why I use
balanced XLR connectors.  Though I have found that I can use RCA cables 
if I use an extra shield
which is grounded to the signal source.  Of course I live near the top 
of a mountain which has many
transmitter antennae, TV, FM, communication, cell phone etc.

Now I wait for Ted and Sonny to tear me a new one. :-)
