Fun thing about Kaftwerk is that they come in two flavour, original and English, sad thing the version is rarely wrote on the disk

German releases have German track lists, English releases have English track lists. The track list is always printed on the vinyl itself and on CD sleeves.

3 of em have different album titles in German:
1977 Trans Europa Express / Trans-Europe Express
1978 Die Mensch-Maschine / The Man-Machine
1981 Computerwelt / Computer World

3 use the same title in both languages.
Here you have to know the disc region or look at the track list:
1986 Electric Cafe
1991 The Mix
2005 Minimum-Maximum

Germany/Austria/Switzerland releases are in German, and only for the 6 albums I listed above, other Kraftwerk albums have no regional variants.

I must take a closer look at the tracklist, I knew only some like Neonlicht and it sound better to me than Neonlight.
This hint will help me to get the right disc, need to put my hand on these to complete my collection !

I agree with you. Maybe I'm slightly biased, I'm German, but I think they sound better in German.

There are extra lyrics and stuff in some songs that is missing in English.

Like "Sekt? Korrekt!" in Das Modell. All the extra lyrics in Computerwelt. Computer Love has more reverb on the voice in English which I think sounds worse. etc.

Yeah, if you can it's worth finding the German versions. Trans Europa Express, Mensch-Maschine and Computerwelt. I think those 3 albums are essential.

Please avoid the 2009 "The Catalogue / Der Katalog" Remasters. They have been compressed and noise reduced. All of them sound worse than the originals. Try to buy pre-2000s Kraftwerk vinyls or CDs, you will enjoy the sound on those more if you care about audio fidelity.

And avoid the 2017 "Catalogue 3D / Der Katalog 3D". It's almost a scam. It's modern studio remakes of old Kraftwerk songs. No need to buy these. The originals are much better.

Thanks for the advice.

Sure, the "modern" mastering is all about maxing out the level and achieve less than 3db of Dynamic range on a device (CD) that can achieve without any trick (dithering) 96db.
This is why a lots of people claim vinyls are better, which is technically false with a practical 30db DR, but when you listen a vinyl with creaks and noise but 12db of DR, it will "sound" better than a 3 DB DR CD !
They just put worst music on the media !

For a same track on my old recycled public address amp (from the 70's formerly use in the village hall so not HiFi at all)
Old CD =>amp 4/10 vu-meter bouncing from -10 to -3
New remastered mix=>amp 1/10 vu-meter sleeping at -6 feel "flat" and hammering my ears
