[sdiy] banana sockets

hello people,
just joined the list, and as a beginner diy-er I must say most of what is discussed is way above my head ( at the moment at least) - I thought jitter analysis was something to do with watching my dad dance! 
 

Well, it varies a lot.  Some threads are highly theoretical and some
are down in the guts and solder.  You just happened to catch us at
a heads-in-the-clouds moment.

Anyway I have a small setup (doepfer, analogue systems/solutions) which is all interconnected with minijacks, these have a tendency to be crap so I want to change all the sockets to banana sockets as these will fit on the existing panels (1/4" sockets are too big) but as banana plugs are unshielded I am concerned that problems may arise (crosstalk, interference etc.) Am I correct, or would it be okay to  proceed with said conversion. I notice that several synth manufacturers use banana sockets, but are the circuits configured in such a way that any problems are negated by their design? 
 

The only thing about using banana jacks is that you have to provide
some means of signal return continuity between the modules.  
I'll let someone like Cynthia jump in on what's the best way to
accomplish this -- through the face plates and rack rails, I would
guess, although it could be done via the power supply return.
There are noise advantages and disadvantages to each approach.
Back-panel wiring to connect all the returns together would
probably be best, but it's extra effort to configure.  If you have
multiple separated units, there has to be some external ground
connection between them.
