Default C.E.C. TL51XR upgrade

Greetings to everyone!
Own this C.E.C. TL51XR cd player is about 2 years and now I decided to make major changes! I was inspired by this for upgrade digital modules: cectl51x

I started with the power module. Here I replaced all regulators with Newclassd UWB DX78XX/79XX regulators.

Of course, I plan to change and electrolytic capacitors with Elna Silmic, Nichicon or BlackGate but it is very difficult to find the right size, I mean diameter!
I preferred to do bypas with 0,1uF/160V VISHAY-RODERSTEIN MKP-1837 Metalized Polypropylene Film Capacitor.

Here I have changed all copacitors with OS-CON and I even supplemented like Lampizator!
Instead 7808 regulator I put UWB DX7808 regulator.

Changes will continue to DAC board!
If you look closely you will see that is assembled very careless!
I even discovered some components (some blue bypas capacitors) that were not soldered!!!
Was assembled in the garage!!!? Big surprise is that it worked!

Here I replaced all Chang electrolytic capacitors with Nichicon on PSU, OS-CON on digital and Elna on analog sections. And of course two UWB regulators +5V, +3,3V found their place!
Instead 4 X 3,3 uF blue polypropylene on balanced output I put 4 X 3,3uF OIMP V-CAP bypassed with 0,01uF/160V VISHAY-RODERSTEIN MKP-1837 Metalized Polypropylene Film Capacitor.
Oil Impregnated Metalized Polypropylene Audio capacitors by V-Cap

To note is that after each stage of changes I did auditions. Each time the sound was different, increasingly better and now I can say I'm happy!
Now I think this C.E.C. TL51XR CD player is indeed Hi-end, can keep up with reference CD transport/player! Investment and effort are well worth!
