I am auditioning a CD player with a 6dj8/6922 Tube based output buffer that has this OP amp on the output Buffer board along with 4 large Aeon caps..Is this a good chip in this application or holding back some potential in the unit?Would possible upgradeing of this make any large difference?I notice folks are regularly upgrading the common 5532 but this is new/improved version[8 pin].Is it linear?Any info would be appreciated.This player just came out and lists for $1675 so using this OP amp if its not of high quality for this application doesn't make sense.The player sounds astounding as is but?Thanks for your input,JD

Good day to all.Need some clarification here since you guys are discussing Op-Amp for CD player. My CD player are using some OP-AMP RC5532DD (8 pin). Just wonder whether is this the the normal 5532 op-amp that can be replace by OP275 & OPA2604 as I could not find the maker name on the IC.
Thank you.
When I ditched the 5532 in my cd player for an OPA2604, the sound improved drastically. Moving up to AD8610/20 took the quality even higher. YMMV.Consider putting in a socket, then you can swap opamps with less pain. Many here recommend the gold-plated Millmax (which I used). Power supply pin bypassing is also a big issue when upgrading - the archives have a wealth of suggestions.
IMO, are plenty of IC's that are better than the 5532. The ad8620 and ad843, are two I would look into. If you decide to retain the 5532, I would, at the least, consider biasing the the 5532 class A.

If you buy what is on here the NE5532 is very hard to beat. Not everone agrees with these findings but you should at least be aware of the opinion expressed by D.Self. At worst, NE5532 should not be classed as a poor opamp but rather as one whose performance may have been exceeded a couple of alternative depending on what characteristics are more important to you.
Also, opamps are not 100% "plug 'n' play" some work better in some situations than others. My advice is self education and make your own decision. While there may be alternatives that sound better, there are certainly many more that sound worse, even much worse. Proceed with caution.
I personally found that 2604 blew the 5532 away completely. It was just more musical, dynamic and made much more sense of complex orchestral pieces. I later tried the LM6172 which in turn blew away the 2604. This improved on everything, especially detail and tonal saturation/purity (after I got the PS decoupling right).Can't believe anyone would prefer the aging 5532 to these more modern chips.

I find the graphs shown to be very biased. On most of the graphs he goes to 50 khz and more. On the 5532, he cuts the readings off at 10 khz. Way below what we consider audio. The same holds true as far as expanding the graphs vertically with the .0001 to .01 bar measurements. Most of the graphs look biased toward favoring the 5532 IMO.
As far as my listening tests, mostly on FM tuners and Sony, Denon CD players. I've replaced 5532 (Magnum Dynalabs, Sony CD and others), 4558 Kenwoods and others with OPA2132,2134 and OPA2604s. These op-amps (to me) really "flesh out" the midrange and sweeten the highs. The 5532 always had a dry, lifeless midrange. Just one opinion. jim...
If I was considering such a swap myself, instead of worring about the scales and visual presentation, I would simply get a ruler and read the values off at each octave point. If you just tabulate, the figure on a spreadsheet, the NE5532 is going to be at the low end of the THD+N range along with some others.It would have been nicer to extend the NE5532 data to 20k, but unless there was some outrageous problem, it would probably still be respectable.
I think the problem is that some rather popular pieces that come from the maker with considerable marketing puffery don't look so good on paper. Nonetheless, if you use one of these and like the sound, who's to complain?
Are you refering to the 8 pin Ne5532AN as well.I understand its an improved version.Thanks,JD
A 5532 is a bi-polar op-amp. The ones I use are bi-FETs. The sound I prefer. Try both types. They're cheap. Use the type you like best. jim...
