Default JVC "EXU-901a" (KRELL KPS-25sc Phase Tech CT-1 CT1) better than VAM1254, CDpro2LF ?

JVC cd mechanism "EXU-901a" (KRELL KPS-25sc Phase Tech CT-1 (CT1) - better than VAM1254 (CD-pro2M + CDpro2LF) ?

Who know more about the JVC cd transport mechanism "EXU901a" (EXU901 EXU-901).
I don't find datasheets, information about optical pick up (laser unit) and order sources for spare parts so as the complete JVC device.
I know about only two cd player brands, where this mechanism is inside:
1) Krell KPS25SC
2) Phase Tech CT-1
to find by follow URLs:
http://www.audiogon.com/cgi-bin/cls....lay&1253308225
http://www.phase-tech.com/html_japan...page_ct-1.html
www.phase-tech.com/pdf/CT-1_catalog1.pdf

Who know more about this transport unit? Thank you for your advices

Reimyo's successor of CDP-777 uses now VAM125x from Daisylaser/Philips; maybe Victor's "EXU-901A" is no longer available and obsolet.

The laser head (optical pickup) of the mechanism "EXU-901A" is the "Optima 4S", also used
in the JVC cd player model "XL-V311BK" (XL-V311, XLV311).
Here a photo URL:
JusTone Lasereinheiten. OPTIMA4S / OPTIMA-4S / OPT4S / OPT-4S JVC Lasereinheit, Laserpickup, Laserunit, Pickup, Laser, Laserkopf, Laufwerk, Mechanism
What is the type number (model number) of the new JVC PRO mechanics you ask ??

Data sheet and distributor address of "EXU-901A" from JVC still wanted.

tiefbassuebertr, only mistake - the laser head (optical pickup) of the mechanism "EXU-901A" is the Optima-4, not Optima-4S

Thank you for this advice. Unfortunately in the first headline of both URLs (blue background, white text) is to read ("Optima 4S").
