Flexy rack threaded rod material


It seems that brass is the universally accepted "best" material for the threaded rods of a flexy rack, but has anyone actually compared brass rod to any other material in a flexy rack in the same room and in the same system? I'm having a little problem shelling out 3x the money for something that is supposed to be better even though no scientific proof exists (or maybe it does, I just haven't found it).

Tom, I totally hear you.

Opinions based on experience or science are somewhat valid, but opinions not based on either should not even waste space in the forums. That's why I wanted to know if anyone actually tried both. Do I think there's anyone who tried steel first and switched to brass? If so, probably like two people in the world.

I just figured that there are so many proponents of brass that it MUST come from somewhere, whether it's from experience in testing different materials or scientific theory.

I particularly love when people claim that brass is better for building various stereo components because instruments are made out of it. Seriously?

Thanks for the down to earth response.
I have used both steel rods and brass rods in one of my isolation stand products, both with good results. At least One high end amp, the Berning EA2-150, has a brass chassis.
I have compared steel all thread rods with brass all thread rods with the same components and the same shelving. One left and one stayed. Oh before that I compared brass lock nuts with the steel lock nuts on steel rods.. again one left and one stayed. That was about fifteen years ago. Tom
Which one stayed, Tom?

I asked myself the OPs question when I built mine. I went with brass, but I'd be seriously surprised if I could tell a difference, sonically, in the event I A/Bed, which I didn't. People who build footers and the like, including people I think well of, like Steve at Herbie's Audio Lab, would likely say otherwise. The factors driving my decision were the visuals: brass develops a nice patina over time, which looks right in my older home. Also, the footers I decided to use came in brass, and I wanted a match. I believe the difference in cost was 200-300 bucks then (the materials make it a pretty expensive rack), and I felt like that wasn't too much to pay for the visuals. With a different decor, of course, the steel might go better (say, if you're a chrome and leather person).

Below is a link to a thread where I got lots of help building mine. For me, the upshot was that although I'm very happy with my rack, with patience I could have gotten better value in a used rack.
