An Issue with Discs Showing Up "Dirty" From My Marantz CD Changer...

dannnielll

Which part of the answers have you a difficulty with?. The most logical and plausible reason for black dust appearing on the discs is black material disintegration in the plastics used in the internals of the drive. Now if you ever opened one up,you will see what we mean. An auto changer has even more moving parts and latching cams etc. Every cycle causes a little wear . The laser lens assembly is constantly refocusing many thousands of times a second holding the beam in line,there are mechanical gears in these assemblies which are also plastic. I have had headphones leaving rims of black on my ears, as the vinyl pvc coat just disintegrated into a flaky dust.
Showing pictures of these machines for sale new,is unnecessary and makes a no value point. Five years ago, I saw brand new 8 track  players for sale in an electronics shop in Saigon

I'm NOT showing PICTURES of these CD changers new -- they're being SOLD via RETAILERS right NOW is my point...and people are BUYING them. I don't see eight track players being sold on a widespread basis NEW, as you were alluding to. TOTALLY different scenario. So what YOU'RE saying is unnecessary and not making a valued point.

Please read these words carefully: I provided that information about CD changers via Crutchfield, a MAJOR catalog and online retailer, because the member who posted before me stated that these are VINTAGE items and alluded that they're totally obsolete...I am proving they're NOT, as there is still a market for them (even local brick and mortar "Best Buy" shops near me in the U.S. sell the Onkyo changer and a couple of Yamahas).

Note the two models on top:

Additionally, that INTEGRA model I included as offered by Crutchfield, made by Onkyo, is actually considered a HIGH END esoteric product...and it's a CD CHANGER.

How is that "unnecessary" to mention?

Even THAT being said, what you mentioned BEFORE you called my posting of these changers unnecessary is what I wanted to focus on -- I wanted to know if the CHANGER mechanism could be causing the dust I'm seeing, or something else, and if CD players themselves can do this, as well.

I never opened one up, so I will take your word for what's going on there (no need to again remind me that it's as simple as picking up a screwdriver). If that IS the case, then I have my answer as to what can be causing the dust/grime...don't know what I'll do, but at least I know where it's coming from.

Well, I've learned something new today - CD changers are still available here in the UK from Onkyo:

I'm still not entirely sure why you're shouting at us, but it seems to me you've been given all the tools by the community to to choose what to do next.

Derek,

I'm not shouting -- I am emphasizing certain words by capitalizing them, but if you'd prefer, I can italicize them.

As for your discovery of the changers -- that is what I was attempting to get across. They are still available and being purchased...I didn't lie about that. The Onkyo model in particular is still very popular across the world; I read user reviews about these things all the time.

That Onkyo is indeed available in the UK and elsewhere...though I'll never be given credit for saying they were still being sold. There is also an upscale Integra model based on the Onkyo that is offered as an "esoteric" high-end choice; the Yamahas are also highly regarded by many in the U.S.

As for what to do next, I am uncertain...but so long as I know what was causing the issue, it's a step in the next direction.

Thank you.

On the Internet, using bold type is generally regarded as shorthand for shouting or aggression. I have no doubt that wasn't your intention, but that is how it comes across.

I still think you've been given some good advice once you weed out the replies that are pertinent to your situation. As with any fault-finding, it's usually a process of elimination, so opening up your player and looking for the telltale signs of decay is probably as good a way to start as any.

Maybe you can upload some pictures of your player's internals so that more learned members than myself may be able to identify this for you?

It was never my intention to show aggression or hostility; many forums I am a member of don't have an issue with capitalizing for emphasis of a point. I appreciate your candor and willingness to thank me -- for anything.

Okay....but I was attempting to explain why I feel the changers aren't so "extinct" or "worthless" as many here alluded to in back-and-forths with me; do you understand what I was getting at now with regard to that?

Granted -- they may not be nearly as popular or preferred as a high-end single-disc unit (they never were, actually, especially amongst audiophiles) but they are still being offered brand new, with warranties and all. I think what most people immediately conjure up in their heads when one mentions "changer" is one of those clunky magazine-style units that exuded horrible quality and longevity; the carousel-style changers, such as the ones I have used and continue to use, are something of a slightly different animal.

I very much appreciate that; let me see what I can do. The fact that I'm getting some replies in the direction of what is actually causing the black marks is a giant step forward for me, as it is was the reason I created the thread in the first place.

Thank you for engaging in a civil, level-headed conversation about this matter; seems to be a dying art amidst the hobbyist/enthusiast internet forum circuit.

Sorry guys but there is a tone running through this thread that has become far too confrontational and it's going round in circles. Locked.
