does anyone sharpie thier CD's???

I get tired of science being brought into what my ears do better. Thats, hearing sounds.

There may be some wanting to hear something and your going to hear it cause it's mind over matter, but to say that we cannot perceive differences in a product that can't be proven by science is crazy and its just placebo.

I proved that wrong in another thread when I mentioned that I guessed 25 out of 25 times where my wife put the cleaver little clocks. Whether she had placed them outside or next to my closed theater door. The same people that say the clocks don't work, its your imagination, its the placebo effect where proven wrong with the cleaver little clocks. Guessing 25 times right of their location is not mere luck.

The same people saying there is no science in the clocks of how they work, thus they cannot work and its a placebo effect shows why science don't belong in listening to audio and that my ears proved right over science. Science smyence, its time to get rid of it and just let your ears decide!

Freemand: We've all read similiar "unsubstantiated" claims regarding just about everything audio related. Humans have been claiming to see, hear, smell, and taste all kinds of things since the beginning of man, much of which can be, and has been disproven by ivestigation/research (science). All one has to do is observe the high medical-placebo percentages, nevermind all the UFO-sighting claims.

You wouldn't have your beloved audio equipment/media if it wasn't for science! And, what claims would audio manufacturers (including Machina Dynamica) be writing in their brochures, other than the science-related data that everyone reads and compares?

Metro04: Very true, but many times over the past several decades scientists have reported discoveries that cast doubt on previously held thories/beliefs -- or are flat-out contradictory to what scientists have "known" to be true. In the audio world, you need a healthy dose of both -- science and the ability (and willingness) to listen.

The idea has been around for 10 years marketed as AudioPrism CD Stoplight green pen & CD Blacklight luminescent green mat. The red spectra of the CD laser is cancelled by green, instead of being refracted back at the edge & across the disk, which increases jitter at the laser pick-up. I believe it works, though it doesn't increase volume. The effect is similar to jitter reduction associated with a low-jitter clock: less glare, more liquidity. I think the Blacklight, which bathes the area with green phosphors, is more effective than the pen, but recharging the mat with a light source every 20 minutes is just too dweebish.

9rw: Yes, your point is true as well, but Scientists are continuously striving for proof and understanding. I'd feel a whole lot better if renowned research teams submitted "proven" technical findings over financially-motivated manufacturer’s claims. This "subjective" hearing nonsense wouldn't fly in any legit research organization (Science/Engineering firms, Universities, NASA, etc) without absolute technical proof/explanation. IMO, I feel ALL claims should require proof by whatever means, including DBTs or equivalent. Otherwise, it's no better than the "unregulated" vitamin, personal healthcare products, or similar "subjective" claims markets.
