Shorting Plugs and Non-shorting Plugs - Wothwhile?

Well, I have a hum that I can't isolate. I've tried all the usual fixes with no luck. I am convinced, however that the problem is interference from some other device (that I can't isolate). I have a bunch of cheap interconnects that I could use for open RCA connectors on my preamp (Tape 1, Tape 2, Tuner, etc.). Is the effort worth it? I certainly don't mind sacrificing a few cheap ICs to the audio gods. If you have an opinion, please weigh in...

The short answer is it is worth the effort IMO, though don't expect magic.

I had some serious background noise some time ago and tried shorting plugs (home made) to try to solve it. I found it helped very little, though did seem to help some. I also found that my problem appeared to be a cumulative effect of bad ground connection (on my TT), connectors in need of cleaning, IC's that needed to be re-routed, and open connectors on my preamp.
