In the meantime I get various CDM12.4 laser heads again.
All ones where is to read "Made in" ... Japan, Malaysia and Taiwan work fine in all respects.

Thus there must actually be a supplier either for NOS from Sharp or good quality copy.

But all CDM12.4 heads "Made in China" (10 pcs) I had to complain cause too low power output.
I must send back all 10 pcs. Thus the hologram diodes from this heads must be a bad copy

None of the wholesalers who buy in the Far East is apparently able to find out, in which factories this parts are manufactured.

Consequently all european (and u. s.) wholesalers purchase always the pig in a poke;
and the Chinese supplier is pleased to have once again sold electronic scrap resp. trash to an European buyer.

Why we have this situation?
Is it because none of the wholesalers resp. large buyers from Europe speaks the Chinese language?

in the meantime I named all compact disc player devices which are not in perfect working condition to electronic scrap in those cases, where CDM12.x/VAM12xx/VAU12xx there are inside - even all very expensive brands like e. g. Krell kps30I, BOW zz-eight, various Marantz and several other so called "High End Audio" products.

there is additional to note, tat the PCM DATA STREAM from an ordinary compact disc provides not a really good sonic quality (only 16bit and 44.1KHz).

what is this?
Original Philips Laser Lens Pickup for Naim Audio CDs II CD Player | eBay (Naim Audio CDS-II, VAM1205 head)
or
Original Philips Laser Lens Pickup for Linn Sondek CD12 CD Player | eBay (Linn CD12, CDM12.4 head)

Very expensive.
But in the text of those auctions I read:
"The lens, optical formulations & coatings were originally designed by Rodenstock in Germany, on Philips' specifications"

This sounds good.
Are there experiences with those parts?

I think these are used parts from old players - this ebay member offers too many 'new' replacement pick-ups (and at high prices) without disclosing what it is he is selling by the part information.
