Best opamp for my cdplayer.
 
Hi, I'd like to change my output opamp in my cd-player?

Actually I've been using the NE5532 but I'd like to try some other.

Could you gimme some advices?

I've just take a look on LM4562 or OPA2134... what about them?


Friendly, Enzo.

if you tell us what make/model, it will be easier to suggest something. but, i've found with all the different players i've had that trial and error was the best approach. just what ever sounded best in conjunction with the rest of my system to my ears. good luck! :)

I don't know about the best opamp for your player,for reasons mentioned in the previous reply by Crippled chicken.
However, an OPA2134 is a good choice that will sound better than the NE5532, without any problems. You could also try the
LM4562, but in some players it may seem a bit overwhelming with it's high frequency detail.

So you have a dual op amp.
First thing is to remove the original carefully and install a machined 8 pin DIP socket.
Then you can change chips very easily. Always power down before changing chips !

Try all the chips you can get easily. You must remember that what sounds best to you is what matters . Use others opinion as a guide but don't consider it gospel truth. Settle for a chip you like best .... it might not be one that many others like and it 'might' not be an expensive variety. Higher price 'need not' indicate better sound to your ears.

I have just tried out a TL072 in an old Philips CD850 MkII cd player. Now I understand why that chip still has many followers . Not the best chip for the job but certainly does a great job in this machine.
I can certainly live with it happily if the need arises. ( I had used an OPA2134 earlier !)

Keep an open mind and listen carefully...........AND .........take time when comparing.
Have fun.
Cheers.

some dual chips used in CD players

Hi Enzo,

For my system I use OPA604 (OPA2604 dual op amplifier). It sounds less linear than OPA2134, but sound adaptation is better on my system.
As say Ashok take time when comparing. Generally you must wait for 48H00 heating before best sounding.

OP Amp for CD-850 MkII
 
Without a doubt!
CD-850 MkII needs at least 24 Hours warmup to sound sweet.
I recently get back my old unit which was with a friend! The unit suffers the usual malware... gear tray broken!
In 1997 i update its power supply with Elna audio series (Standard- Metallic Red) and a pair of BB OPA2604 DIP and a OPA2604 SMD for variable output. It was imediate the upgrade this Opamps gave when i compare it to LM833 and NE5532.After 2 years i try BB OPA2134, still it are more open and detailed, and for my taste it made a good job and arent so expensive as other chips!
So recently i listen again the "Fat Lady", and "goshhh" it sound very good indeed, so much detailed and dinamic, and after a 24 hours warm up, the treble tamed, and the sound become more gutsy.
I compared 2 or 3 cds with my Sony SCD-XA3000 ES!I like both palyers, each of them with it own signature! Despite the aging of Philips it is a very good cd-player!
P.S. Get good capacitors and opamps, and get rid of the fuse resistors in serial with the supply lines of the opamps and dac SAA7350. The dac have 6 power lines, check the schematics and the SAA7350 datasheet!
A remarkable piece of electronic audio engeneering!
The CDM4 transport can read CD-RW 10X with multiple recordings and read once recorded CD-RW 4X.
What are we asking for a cd player with 15 years of existence!?
Kudos for Philips!

Regards

I was playing around with all the "hot" and "hifi approved" opamps in a CD player recently. Tried all the latest and expensive options. Ironically the best sounding opamps for this particular application were ne5534D's. They cost about a $1usd a piece.

You never know.

Original Marantz CD 94 use JRC 5534D. Update to OPA604 greatly improve sound.

Hey Eric,

I cannot argue with you about the 5534D. I was seriously surprised when I popped it in on a whim and it sounded better in my unit. Probably one in a million chance.

-David

BTW, anyone should test out what they have in the parts bin. These ne5534D's I pulled out of one project and replaced with AD797's actually sounded better in another project. For me I started setting aside preconceived notions of good and not so good when tinkering. It's the surprises that are fun for me in the audio hobby.

A year ago i saw a review of a high end cd player from Luxman that use in final output stage JRC 2114, wich is the same that Sony use in SCD-XA3000ES, SCD-XB970 and others with exception to SCD-XA9000 ES, which use OPA2132!
One thing we must learn, an optimized power line to the dac and output buffers is crucial for the device perfomance!
Check what opamps Esoteric SA-CD and DVD-A players are using or use in the past! I think they run with JRC!
In the posts JRC 2114 arent quite apreciated, but i think they are not bad! I believe that some opamps are more sensitive to psu noise than anothers, and capacitors have distinct sonic caracteristics regard the effect that higher capacitance usually gave to the sound!
