There's only two things that smell of fish. The other ones fish.

But there is nothing voodoo to do with it. The light from the laser is focused to a tiny spot on the rear surface of the CD (almost in the plane of the label). Since there is no refractive index matching, light is partially reflected at the polycarbonate/air boundary, and, particularly on the outer tracks (the later ones, since a CD tracks from the inside out - ie opposite to vinyl) there is a more than decent chance for that light to get back up through the optics and add a noise-like component to the received data. Thus it adds either an increase in bit-error rate, or adds jitter - or both. All the green or black pens do is act to absorb any such rogue scattered light and stop it getting back up the optics. But violet energy patterns? What pseudo-science clap trap. I use a black pen to darken the inner and outer edges of all my CDs. It makes engineering sense to me to do so. I also use a Nespa Pro finalizer to 'process' the bubbles in the polycarbonate, a process which makes a lot less engineering sense but which most definitely works for me. |

I always pen my CD edges with permanent green marker and they sound better as a result!!!! All the green or black pens do is act to absorb any such rogue scattered light and stop it getting back up the optics. Black?!! It 'has' to be Green, sir! |

Had I best not mention the small piece of foil on the TV screen at this point? I use the foil off a Kit-Kat. Don't get chocolate wafers with Mr Belt's products, do you? Does it work then? |

I also use this too www.audiodesksysteme.de/index.php?kat=10_17_6 . Does it make a difference? Yup - a very significant one IMHO. More significant with harsh recordings, which are rendered much more listenable to. |

I've looked at getting one of those, Craig. You may just have pushed me into a purchase.

I've looked at getting one of those, Craig. You may just have pushed me into a purchase. Not cheap - and the same price from AudioConsultants and Russ Andrews, so there doesn't seem to be a was of reducing the outlay. I bought a cheapo (ie the cheapest!) vacuum cleaner from Argos to push into the hole in the back to suck out the swarf. I also use RA's ReVeel wipes to get rid of mould release agent and ReLees (what naff names) antistatic spray on the label side of the disc. It all ends up being a bit of palaver, so I usually work myself to a frenzy and do maybe ten or twenty discs at the same time. RA also does sticky labels for the jewel case with tick boxes for what you have done to a particular CD. By comparison with the www.audiodesksysteme.de/index.php?kat=10_17_6 the rest of the stuff is only a few quid. Oh - forgot that I usually wash the discs with ReVeel first before using the Nespa. UV stands the risk of polymerising mould release agent, so I get rid of that first. |

I use the Auric Illuminator kit to clean the discs and do the edges with their supplied pen. Then into the Nespa for 60s each side. Some discs are greatly improved, others only a tiny amount, but it's always worth doing. As it's such a faff I just treat any disc not previously treated when I'm listening. I put a couple of dots on the inner part of the disc to mark what I've done.

I just bung in the CDs and play the feckers. Life's too short to be arsing round with felt tip pens.

I tried a few of the PWB tips back in the day. I Remember using a staedtler lumocolor violet pen to mark inside and outside edges of the disc with an odd number of 1cm dashes. If definitely had an effect and it was to my ears, better than the green pens around at the time.
I bought a PWB CD stabiliser with blue and yellow circles on it. That made a big difference to CDS. I'd still be using it today if I hadn't left it in the drawer of a player I sold. I also heard differnces using electret cream. Also a CD shorting device for unused digital outputs (a treated phono plug with a 1 million ohm resistor IIRC). PWB were also the originators of removing speaker wadding (via Jimmy Highes).
Not everything I tried worked, Spiratube didn't seem to do much to my perception and electret foils on my speakers made them sound worse to me. I'd be up for trying more things today if they were inexpensive or cost nothing.
I'm not claiming anything for the products beyond my own perception but I'd say "don't knock it without trying", especially if it's free.

Belt historically a combination of moderately sensible ideas (like CD stabilisers, screening plugs for digital and analogue unused I/Ps, line around CD etc) and a whole load of pseudoscience and really whacky creams, foils and potions . And he seems to be getting whackier as he gets older.
But so am I.....the men in white coats are coming.....

Well, it could just be my imagination (running away with me), but there does seem to be more… snap & bite to things. I tried a few of the PWB tips back in the day.

I don't even own a TV, and I still haven't got time to be arsing round with felt tip pens, fancy mains cables, or buckets of water. |

I found this on a dealers web page.
"Free Sound Improvement
When listening to your audio system, try turning off your wireless router and all mobile phones. The sound improves by quite a big margin. Tonal balance becomes more natural with more authority and, most importantly, the sound stage becomes much more holographic. And it’s free!
Go on, you can live without being connected for the sake of an evening’s listening pleasure."
