All the CD’s I have burned of Audacity WAV-files (version 2.3.0) can be played on any CD-player EXCEPT the one I use the most: MARANTZ CD4000.
What can be the reason? I already tried several burning programs and different CD-recordable media.
Just to confirm, you are making Audio CDs, right, not Data CDs? When you burn the disks, did the software give you the option to change the 2-second gap between songs? That only happens on Music CDs. If you put one of your disks in a computer, it should not give you a list filenames. That only happens on Data CDs.
The Marantz plays everything else, right? Does it play home-made disks made by anybody? I’ve heard of players that refuse home-burned disks – full stop.
Those of us that went through the beginnings of his process know that sometimes changing the burning speed can greatly affect the playability of disks. If you are burning at maximum possible speed and your burner screams at you while it’s working, then you should try X12 or slower.
It seems other people have had this problem.

I’ve burned several type of CD’s (Philips, Verbatem) with different burnspeeds: same problem.
I also changed the wav-file into MP-3: same problem.
I’m running out of options, I hope you’'re not!
Google threw this up: http://www.diyaudio.com/forums/digital-source/5358-do-not-buy-marantz-cd-players.html
The replies say that they have not experienced the problem, but they do not say if they were burning TAO or DAO whereas the original poster specified that his/her problem was when burning DAO.
DAO is required for making “gapless” CDs. Good CD burning programs should have an option for enabling TAO/DAO modes - check that you are using TAO.
I’ve burned with both TAO and DAO. Makes no difference.
Are you able to make CDR disks that work on the Marantz using audio files that have not been made with Audacity?
What CD burning software are you currently using?
Yes, I think it’s related to Audacity-software, because before I’ve had no problems at all. The burning software I use is both Real Player en Nero.
But what can be the reason why a “normal” audio-file like 'wav or 'MP-3 cannot be played on a simple CD-player like Marantz.
Could you try that again as a test.
Nero should be able to convert any audio format that it supports so that it works, and if the format is not supported Nero should throw an error, so I can’t think of any reason why files created with Audacity should be any different from other files - Nero should either accept them and work, or reject them with an error message.
Note that there is a difference between “audio file” and “audio CD”.
Standard “audio CDs” are not “files” in the normal (computer) sense. Audio CDs are a special format of raw data, with separate track information that tells the CD player where to find the data that belongs to each track (Compact Disc Digital Audio - Wikipedia)
Computers are able to read “audio files” from “data CDs” as well as playing “audio CDs”. Many standalone CD players are not able to play “audio files” and will only play “audio CDs”.
Another possibility is that the CD drive on your computer may be wearing out. (The optical drive on my laptop became unreliable after about only 1 year 
). Some CD players are a lot more fussy about the CD “burn quality”. Some versions of Nero include “Nero DiscSpeed” (also available in the “Nero Free Tools” section here: Nero Download Center - Overview) which can test the burn quality.
Yes, the sounds on an Audio CD are not sound files. That’s why you need a ripper program to “convert” an Audio CD so you can edit the music.
Don’t fall in love with MP3. That’s a delivery or internet format and causes sound damage when it works – and you can’t stop it or fix it later. The sound on an Audio CD is perfect WAV quality and you want to keep it WAV as long as you can.
