Seeking warmth and good sound, because sometimes I found this CD player sterile and overly analytical, somewhat harsh and fatiguing.
Is it a good idea to try to replace the NE5532 op amp in my Sony CDP-XA3ES?
What do you recommend? improve the sound?
OPA627, AD826, BD2134? Should I use the same for the I / V and the output buffer?
Someone has done on this CD player?
Any better to add? Capacitors, etc..

An externally hosted image should be here but it was not working when we last tested it.
Opa 2604 on output would probably be reasonable starting point towards what you are looking, that's what sony used in XB 930 UK edition i have. Or, you could check the swap meet, there is someone selling his zapfilters right now. If you decide to go that route, it will take it to completely different levels.

+ 1, Yes. While you are there, please also consider changing those cheap cinch's with something better and upgrading your clock, it made a big difference in my Sony at the time. Install DIP sockets and you can try different opamps until you are happy with the marriage with the rest of your system and your ears.
Happy tweaking!

Not at all , few if any op amp can match the 5532/5534 as I/V converter.Almost any newer generation OpAmp will fair better as I/V converter. Or have better results as filtering stage.

OPA2604 has higher noise and distorsion than the 5532...
But is faster...
Anyway, personally didn't find it really better sounding - compared with LM4562.
As for 5532 - it's just a mediocre OpAmp for the I/V job. 5534 is better than it, but there are other singles that are also above 5534:

I found the THS4031 flat and boring. Now I am using OPA627 biased in Class A (1.5k resistor from output to negative supply).And what about THS4032? Any experience in XA-_ES player?

If you see the photo I post, which one to replace? IC602 or IC603?
Where do you bouth this chips?
Thanks.
You have three OpAmps per EACH channel there. Converters seem to be 503 and 603.
To be specific: Do I install OPA2134 on ic502 and ic602 and on the other hand AD627(dual) on IC503 and IC603?
Is this a good solution? Or tell me another. And sorry for my ignorance in electronics.
I need to improve the sound of my beloved XA3ES.
Before You replace the op amps there are other mods you could try.
I have not found a schematic (that I could download for free)!
But looking at your photo has the CD player output stage seems to have muting transistors. If they are muting transisitors they will probably be positioned in the circuit to pull down the outputs. If so, these usually can be removed.
You could probably also remove any DC blocking capacitors if you check that there are no excessive DC offsets.

Again I doubt arise. LM4562 or OPA2134.
I'm going crazy. At the end buy a new player.
Why doubt ? I thought you liked the player
The OPA2604 is the one to go for if you want the most "analogue and non fatiguing" sound.
The OPA2134 is less coloured but we are talking subtleties.
Either should easily better the 5532's fitted.
I havn't evaluated the LM4562 so can't comment on that one.
For what these parts cost and the few minutes it takes to swap them I can't see the problem tbh
