Remember the green magic marker pens that were supposed to 'soften' the highs.hehe. I had a couple of those CD rings...

Yes, I do and only around the edge...lolRemember the green magic marker pens that were supposed to 'soften' the highs.
Both the rings and the pens, and yes it was because I read about it Stereophile. This is, what, 30 years ago? There's a lot of talk at this forum concerning the in-audibility of DAC distortions in the signal chain, but 30 years ago this was a real thing. Back then, for whatever reason, my sense was that CDs lacked focus compared to good LP playback*. So folks were grabbing the snake oil. The green marker did no harm, but those rings for CD damaged CDs and transports. Attempting to remove the rings usually rendered the CD unplayable.Remember the green magic marker pens that were supposed to 'soften' the highs.
Not paywalled, just delayed. AFAIK, all addended measurements and follow-ups have been appended, as they become available, to the original reviews posted on the website. Of course, if you really want to get an official answer, asking it on the Stereophile website is the most appropriate way to get it.So are the latest and greatest measurements paywalled now?
I still have an envelope of unused green plastic-film discs for anyone who wants to repeat history.Remember the green magic marker pens that were supposed to 'soften' the highs.
Given the amount of gear the mag reviews I'm sure Atkinson is swamped.
PS: I was going through some old Stereophile issues for historical purposes, and during the late '80s and early '90s it brought back memories. Back then, not only were interconnect wires a big topic, but CD 'rings' which were supposed to somehow damp or otherwise improve digital playback were the latest and greatest. It was laughable back then, and truly ridiculous now, looking back. But I wonder, are any of the magazine's reviewers still using these little 'sonic marvels'?
And spraying ArmorAll on CDs. That was an embarrassment.Don’t forget the green pens, amazing Radio Shack portable cd player, and adusting the inner tubes used to float components to tune their sound.
The "amazing Radio Shack portable cd player" [Optimus 3400, a re-badged Awia unit] happened to have a really good transport mechanism. As a CD player, it rolled off the top and bottom, sounded "soft" like old Dynaco tube gear. The coax spdif out jack was a nonstandard 3.5 mm, so I had to cook up an interconnect. But hooked up to a good power supply, the transport was great.Don’t forget the green pens, amazing Radio Shack portable cd player, and adusting the inner tubes used to float components to tune their sound.
I came across that in a column by Sam Tellig, who started out writing as the Audio Cheapskate but for some or another reason changed his handle to the Audio Anarchist. I couldn't tell if the part about spraying the CD was tongue in cheek, or if he was really serious. When reality gets too absurd it's hard to know.And spraying ArmorAll on CDs. That was an embarrassment.

Complementary colours are an artefact of the human visual system. At the physics/optics level, it's just different wavelengths of light.The green pen tweak -- to my way of thinking -- epitomizes the "things that make just enough sense, when properly presented, to give some folks pause". To wit, folks who know a little about optics and the properties of light waves, and who know that green is the complementary color to red.

That trick works only for humans and other animals with similar colour vision. Birds and insects, for example, won't see red, green, and blue light combine into white. The photodetector in a CD player certainly doesn't "see" colours like this.Well, yes and no. Get three flashlights -- red, green, and blue, and shine 'em at a white wall and see what happens.
Or, try some dabs of cyan, magenta, and yellow paints.

I kind of conflated primary and complementary (which was a gaffe on my part) -- but the relationship between red and green is pretty salient to anyone who has ever seen a colo(u)r film negative.

Right. I didn't say it "made sense" - I did say (or at least I strongly meant to imply) that it could be construed as making sense.That trick works only for humans and other animals with similar colour vision. Birds and insects, for example, won't see red, green, and blue light combine into white. The photodetector in a CD player certainly doesn't "see" colours like this.
Although I don't believe in the "sonic" benefit of the green markers, I did have one CD which mistracked at a certain point on my Phillips CD player. I applied the green marker and it didn't mistrack anymore. So the marker is doing something.The green pen tweak -- to my way of thinking -- epitomizes the "things that make just enough sense, when properly presented, to give some folks pause".
