Yes, balanced cables make a huge difference. I knew it before but got
a real reminder when our group got a couple of new mixers with good
balanced inputs and good preamps. Good cables are very expensive, I
think, but worth it. It nearly kills me that I can't find anyone here
who will repair them when they go dead. One of the folks in our group
owns a video studio here and I asked him last Saturday night "Mike, who
repairs your cables when they need repair?" He said he just tosses
them and buys new.

So ask around the studios, broadcasters, ... in your area, if you can
solder or are willing to learn how. Might be able to get some free
that are repairable. I'm probably going to buy a soldering rig and
re-learn something I learned about 1958 but haven't done in 30 years.

If you're in the US or Canada, contact me offline; I got a few I'll
give you if you'll fix some for me. I can't seem to toss bad cables.
Must be something about how scarce things were when I was growing up;
we fixed things that broke or did without.
