one way to improve sound - DIY -30Cdeep-freeze

Hi, to whom it may concern.

I am pleased to have aroused some overwhelming reaction on cryogenics & deep-freeze on audios. Strange to say, this is a NOT new technology at all. It is a decades-young business.

To make the long story short, yes, my humble 30C deep-freeze treatments done couple years back to my audios was, IMO, a little tweak to improve sound. It is NO way to replace or even to compare with industrial cryogenics (-190C/310F) in a liquid-nitrogen
chamber.

The bottom line of this little tweak is - it works for mine, period.
Whoever wants to improve the sound of its rigs can follow what I
have done, with no money involved, & with NO guarantee of success as
it depends on how analytical is the rig involved. A lousy rig may not show the sonic improvement.

(1) Preparation:
put the parts/components/cables/wires, or whatever
in a zipper polybag, squeeze out the air, & seal it airtight.
Airtight is to prevent condensation inside the bag.
(2) Pre-deep-freeze:
store the bags of materials in the frig at 0C for 24 hours
preferrably in a constant temperature environment, e.g basement.
(3) Deep-freeze:
put very quickly the bagged materials into a freezer in the
basement at -30C minimum & store there for 48 hours.
(4) during the deep-freeze period, do NOT touch or move the bagged
materials to prevent likely physical damage to plastic/rubber/
synthetic part of the materials which can become very brittle at
deep sub-zero temps.
(5) Post deep-freeze:
move back immediately the bagged material to the frig at 0C & store there for 24 hours. Make sure the moving is very STEADY & swift. NO shaking or jerking of the bagged materials at all. I recommend a plastic box to hold the bagged materials during the entire deep-freeze to facilitate transit of the bagged materials from freezer back to frig.
(6) Warm-up to ambient temp:
wrap up the bagged materials in thick comforters or blankets for
12 hours. I recommend throwing into the bundle a couple of frozen
jelly packs to slow down the warm-up.

Constant temperature environment is highly recommended, e.g. in the basement.

That is what I have been doing in deep-freezing my audio stuffs.
I just borrow the idea of slow temp-ramping of cryogenics. I works with my audios.

It reveals more inner details of the music textrues, improves the
over sonic perspectsives, e.g soundstage dimensions, airs, image
sharpness, etc etc. IMO, it is a healthy step towards better sounds.
Its costs one nothing, except a few days' patience. What the hack!

To make the deep-freeze more enjoyable, I also 'brask-in' the newly
cold treated parts/components with white noise for 24 hours non-stop.

Good deep-freeze listening

PS: It is another heathy touch to audio by feeding them with white
noise from time to time, to 'flush out' any residual sonic
contaminations in the system.

For new equipment, we call it 'breaking-in'. It is found
particularly crucial for interconnects, power cords & speaker
cables. For DIYs, inside hook-up wires should be run-in before
soldering in. Or simply 'break-in' the newly completed amp with
white noise into a dumpy speaker load for a few days before
auditioning it .... if you got the patience!

I read some blind-test challenge to cryoing or deep
freeze from some nay-sayers. Why don't they just try it out
first & prove it invalid subjectively before yelling & stamping
their feet, simply on speculation? Bear in mind a lousy system
may not show it works!
