Hello
How much time the laser head of a Denon DCM420 cd player are lasting ?
Thank

It depends on many factors, including how often it is used, how dusty an
environment it lives in, whether it is a heavy smoking household and so on.
What's your actual problem with it ?

Gaetan said:I want to modify my cd player, it was manufacture in 1991, I just want to
know if the laser will last many other years, so it would worth to work on
that Denon.
John said:Pray tell, exactly _what_ modification are you making that concerns you
about the laser head life?
Gaetan said:Changing for better Dac, changing the I/V op amp, and few other things, It
just that I don't want to do that to see the cd player laser to die after
few other months.

John said:I'm not into the golden-eared modifications, truth be said, I'm half deaf so
it's all wasted on me, however:
Aren't there pro-level CD players for this?
Or are the mods a cheaper way of doing it?
Honestly, I don't see any mod making a huge difference, is this for some
specific purpose where the analogue reproduction is more important than just
trying to impress friends with music they couldn't tell the difference on anyway?
Gaetan said:Pro-level cd player are to costly, the mods are much cheaper or i may use
the spdif out ans another Dac.
John said:Ok, then wouldn't it make sense to use SPDIF? You at least get a choice on
CD player, and in the event of failure, just replace the player.
You're stuck of course till the end of life of the SPDIF interface, or
failure of equipment whichever comes first, but that's going to be some time
into the future, so why worry?
By the time that happens, it will likely be near the end of life of the
Redbook CD standard anyway, and you would be better inclined to move to
whatever the next whizz-bang standard is.
Unless I'm missing something?
Gaetan Mailloux said:Hello
Yes, I did think of using SPDIF, I even think of using a good cd rom
drive since they have better mechanic.

Why using a cdrom drive are debateable ?
Thank

I didn't say that there was any problem *using* one - only that it is
debateable as to whether there is any improvement in quality over a
'conventional' drive. I see many many CD and DVD players for repair, and a
good deal of these use pre-built OEM drives in them of exactly the type
that you would find in a computer ie with an IDE interface. They seem to
suffer deck related problems just as much as players fitted with
'conventional' drives. I also don't think that they are particularly any
more long-lived in computers, than they are when used in HiFis.

If you wanted a player to modify whose laser and deck was going to last for
ever, then you could do a lot worse than one of the Pioneers from a few
years back. Although they used to suffer from a bad spindle motor after very
prolongued use, this item was quick, cheap and easy to replace. On the other
hand, I can't remember replacing more than one or two lasers in Pioneers
since they were first building CD players.
I would have thought that the way to go if you really wanted to experiment
with a better DAC, was via the SPDIF or co-ax outputs from a conventional
player. What comes out of there is data, is data, is data, basically just as
it rolls off the disc. I seem to recall that the magazine Elektor
Electronics have done a couple of external high quality DAC construction
projects in the last couple of years. Go have a look on their website, where
they have all of the articles archived and catalogued for search.
