To cryo or not to cryo

Hdm,
You are exectly right. Without scientific facts this forum degenerates into "He said / I heard" nonsense. That is my point exactly.
For instance, you give us the example of freezing your CDs. I have no doubt that you honestly think this helps. Maybe its great - I don't know. But tellling us this in a vaccum does no good at all. What I am trying to spur is a dicussion about WHY it makes the CD sound better. Because if it REALLY does sound better then there should be some physical, measurable change. We need articles or explanations from actual scientists as to what (if anything) is happening at the molecular level that make a laser read a CD better after you make it really, really cold.
Of all the hobbies I have been envolved in none is as riddled with pseudo-scientific gimmickry as Audio. I think the reason is that audio quality tends to be subjective by nature. After all, if you say that this tweek or that tweek "sounds better" to you then who am I to say it doesn't and no audiophile wants to admit that he "just can't hear it". The problem is that just because you say it sounds better doesn't mean it really does (in a physical sense). In short I am trying to back up subjective judgement with scientific evidence.
(I use the term "you" a lot but its just for illustration. I'm not picking on you personally)

Ross, seems to me I just gave you a measurable difference above relating to lowered resistance in wire/receptacles following cryo treatment. Does that not count? Now if you want to tell me I can't hear that measurable difference, or that I am imagining it then we are in exactly the same boat that all these cryo threads end up in. As I said, search the archives, or better yet, do some real research or experimentation with cryo yourself. Here's a site with some interesting info (note it's from SUNY at Farmingdale and not from a cryo company):

Also note the remarks with respect to welding and copper tips, which may explain in part the reason power cables, interconnects and speaker cables all sound different to me following cryo treatment. As to CD's, I have no idea why they would sound so different (perhaps reduction in residual stresses in the CD resulting in better reading of the laser and less error correction, who knows and I don't care).

If measurements were all that were necessary to make great audio, I'm sure I'd be happy with a Bose wave radio. And every piece of similar equipment at varying price points that measured the same would sound the same. Science could explain everything and we'd all have perfect sound on the cheap. Believe me, I certainly don't subscribe to the theory that you have to spend huge amounts of $$ to put together a satisfying audio system. My system is pretty modest by Audiogon standards. There are lots of tweaks that I'm skeptical about and wouldn't pop the money for and there's certainly a lot of overpriced crap in audioland. I just don't think that cryo is one of them. Considering the fact that you can probably cryo every piece of wire and all receptacles that your system is running on for the price of 2 or 3 new CD's or records, I figure it's a huge bang for your buck in terms of performance. Then again that's based on my subjective experience and my ears.

That's the ticket. Now we at least have a starting place that's not based on perception.

Perception is underrated. Example: How do you buy a TV? You walk into the store and say to the salesman, let me see some of your best TVs. Then you look at 3 or 4 TVs and you pick the one you think has the best picture. At no time do you ask the salesman a technical question (How many pixels per inch? LoL) or ask to see the spec sheet. I.e., you make your choice based solely on your perception.

But how many people (videophiles?)"cryo" the PC on that same TV and then claim that the picture is better?
