geesh... like I told - high ripple current spec doesn`t make it certainly better. Stop seeing only numbers on paper, use Your ears and find out what fits best for your setup and hearing.
This capacitor thing is subjective and there`s no certain best choice. I gave 3 different suggestions to try out what I thought sounded best and who`s going to change caps should definitely test different ones and not choose based on specs on paper.
 
Btw, what HPs are You using to test capacitors?

babs, I have one really crazy question for You - is it possible to somehow add remote control for DX50 rev/fwd/play/stop button functions?

Do also more Your own research and think. If You can`t handle those things, take it to electronics guy. I told You in beginning that those upgrades aren`t so easy like plug-n-play

 You didn`t even know what breadboard is and how to connect caps wires. Sorry if it sounds harsh but we aren`t Your personal electronics teachers. There`s internet - use it.

As I said in previous post:
 
Anyway, i have try the ADA4896-2 for the differential amplifier, and I love it! its my actual differential amplifier
but, warning,  its a extreme MOD! do not try at home!! (page 5)
 
You must carefully pry the little pin to extend them as much as possible
And solder them to the pads with lot of solder
Need binocular microscope!
 
I will try to post a picture tonight

Eneglish is not my first language,so never heard that word before!changing caps is the only mod I will do by myself,for the rest I have a guy from a phone repair shop!I don't know so many things,but you have to appreciate my willing! :D  just want to squeeze the best from this player,and I almost got everything babas told us so far he did! I was so impressed about how small is that ADA8496-2 beside the original part,and you can see that from the picture!

The ADA8496-2 is an MSOP-8 type component; pin pitch is 0.65mm, yes its small, but its a pretty standard pitch today
At work, we solder lots of 0.5mm and even 0.4mm parts
(Not me ! ... my technicians)

Yes, i actually try some new mods, as you can see on the picture, the board just above the OP amp is pretty dirty...
I am not finished yet, but I think I am near the end
I will return on that soon
