I know Cryoing certain audio parts:tubes,outlets,cables have met with mixed sound improvements depending on materials but since Cryoing improves metal strength was wondering-would Cryoing a metal rack would offer much better sound due to improved strength/rigidity?

no steel no ringing, mass loadable and dirt cheap. Regards.

...understand the benefit of mass-loading.Thanks,
Pete
well two things happen that are beneficial. If you load the stand collum with sand then the sand will increase the weight of the structure which provides greater coupling to the floor and means better energy transmission away from the speaker. Second the sand particles can vibrate and when they do so it results in friction which means a loss of energy from physical motion to heat.(which is what insulation inside a speaker cabinate does). The sand damps the entire structure eating up resonance that you don't want. That's about it. Some folks believe that mass is the key issue and use lead shot rather than sand. I believe that you want a combination of loss (as a result of particle friction) and mass. Hope this helps. Talk to Noel as he is well experienced or you can read the reviews on Skylan products at 6 Moons. Regards.

"The sand damps the entire structure eating up resonance that you don't want."...because heavy things require more energy to set into vibration that may be audible than light things. The real result is that the resonant frequency of the heavy thing is lower. And low frequencies require more energy to be audible. So, it should work.
....while I have not done this directly, I do know a highly-regarded manufacturer who cryo-treats everything but his acrylic shelving, and he told me specifically that the treatment (utilizing Cryogenics International's patented chamber at -320F.) "makes a substantial performance improvement". And yes, he did the necessary before-and-after comparisons. The same goes for his amp & speaker stands, and equipment supports.
I'm imagining the cost of doing so isn't exactly cheap, however I could easily be wrong on this.What type of metal is your rack made out of? Hopefully it's not steel.
If you're willing to go this far to have the best performing rack possible, why not replace your current rack with something made from less resonant materials?
After looking at what was out there and the cost, I decided to make my own rack from composite materials (the materials I also created myself - yes it was a lot of work), and got very good results. My DIY rack is far lighter and stiffer than the DIY flexy I was using, which was made of 5/8" aluminum rods and birch ply shelves.
Best of luck,
Pete
The Mana rack is a flat angled iron rack-in which it's sound (fast attack on notes)is based on rigidity and tuneability.It's a totally different design philosophy than most other hi end racks which try to be as neutral as possible-(not adding anything to the sound of the components themselves).This being said I have replaced some of the tuned glass shelves with Neuance constrained layer daming shelves that give a great decay on notes as well as attack.
'That path' being the replacement of very resonant materials with non-resonant ones (trading the glass for the Neuance), you'll likely begin to enjoy more and more of what you are enjoying about the Neuance. I understand you probably have a lot of $$ invested in your rack, but something steel does very well is store energy and release it over time. In my experience, this results in audible smearing, which leads to sound production rather than faithful reproduction (I'm fully aware this type of sound production can be pleasant, however).If you like the sound of what you have, then you should ignore me - enjoying your system is what it's all about, particularly if you enjoy the gear you already own.
Best of luck,
Pete
Will all due respect Pete,Mana is resonant on purpose.The glass is tuned by strips on the bottom to resonate at specific frequencies and the rack reinforces the sound of the components that are placed on it rather than made to sound acoustically dead as possible.It's a thrilling/pacey Flat Earth sound that makes rock/pop come alive.That being said I still like the Neuance shelves because they not only bring out the leading edge of notes but the decay better as well-improving on the Mana philosophy.

I saw a pic once of the mana shelves and was wondering....
I believe in "cryoing" but I don't believe its effect is due to any strengthening of metals. Especially not when other materials respond similarly to freezing temps. Everything I've frozen has had a positive effect, so if you are able to freeze an entire equip. rack, I do believe that it would be of benefit to your overall sound.
take some empty LP covers, or pieces of normal cardboard, and slip them under your gear. let it settle for a day and give a listen.for my cdp i have 2 covers side by side and not touching. for small gear 1 cover is ok.
my rack sounds toxic & this free tweak works like a dream. I'm just interested to know it it helps a nice rack like yours...
I've had my rack for 4 years, just did the paper trick 2 months ago. before this i woulda laughed if someone told me the rack 'sounds' like something.
Seems I've heard this before somewhere... can you explain it in more detail? Is the equipment meant to sit on the cardboard, or is the cardboard simply meant to sit under the component, not touching anything but the shelf?
I have done the home freezer/fridge version (and please don't tell me the difference in temps, I know I know) on cables and plugs and CDs and heard differences... sometimes.
If you have an old chest freezer in the Garage and there is room you could try it for a day or two for no cost.
The problem is remembering how it sounded before...
