Snake oil and tweaks that work!

This is in no way intended to bring out argument but discussion of tweaks people have tried and have found success with. I know there are at least 50% of you out there that think everything in audio is snake oil, and you are initialed to those opinions. Please don't make this your battle field! If you want to start an opposing thread calling us nuts and getting in arguments please do, it might be fun to have both going. I want this one to be an informational for people who want to try things. I for one have tried a lot of the recommendations in Stereophile each month, most don't work for me, but I have found a few things that do work. #1 tweak: Speaker location. Even a 1/16" can make all the difference. I try to play with this about every six months. A dedicated circuit from the panel with 10ga. wire had a very noticeable improvement. Cables and wires matter, some have been good for my system, some real bad. We have plenty of threads covering this so lets no go there. The "Bedini Ultra Clarifier" works amazingly well for me, I know it's crazy but it works! The Cardas caps I got for X-mas really worked, they produced a more quite background, go figure. Black Diamond Racing "the Puck and the Shelf " have been great improvements, all the different cones I've tried change the sound, I haven't found one I would recommend. The Audio Prism Quiteline filters work great, but power conditioners and RFI/EMI ferrets did nothing. The last thing that has helped me is furniture location, I find if I move something only an inch it can help or hurt. I look forward to hearing others experiences.
For those of you using springs or spring based devices, or thinking of it, here’s a heads up! You can get better isolation, at least on paper, by mass loading the springs as much as possible. Springs can be loaded to the point where the coils almost start to touch. This usually means compressing the springs about half their uncompressed height. On the other hand, depending how soft the springs are and how tall, you might need to observe center of gravity issues. So, keep additional mass COG as low as possible.

Since resonant frequency is a function of the square root of MASS if you can double the mass you can lower the resonant frequency by about 30%. Remember that the total spring rate in the equation for Fr is the number of springs x spring rate per spring. For springs, as a general rule, the way things work out is the best you can do is about 2 Hz. Even when you minimize the number of springs and maximize the mass. Which is actually very good, indeed. But you won’t be able to get down to 1 Hz without resorting to more uh, severe methods. Since a lot of seismic energy is in the region 0-2 Hz, the lower the better rule applies.

Of course how the component is interfaced to the top plate and how the top plate is interfaced to the floor or rack is something worth pursuing. And damping the top plate is another area for investigation.

Pop quiz - Anybody ever construct a double layer mass on spring platform?

I have not yet done that.. 

Man, I always forget to mention that you also sell springs.

I can't believe I'm reading somebody deriding engineers for being obsessed with good circuits and not considering snake oil enough.
It's okay, because I don't believe that you have that read that. Who here stated that engineers should consider snake oil? Please provide some quotes. Or, do you just feel  free to label anything you like snake oil, and then blame us for your righteous indignation?
