What's the difference between op amp? (OPA2132,NE5532,JRC4558,5532DD)

[@gamiwv]

I prefer NE5532 . Piano is extremely demanding to reproduce (NE5532 has EXCELLENT but not fatiguing "attack") and I have the track (in "Day dreaming" CD) so I have "a reference" without YT compression, to compare. I also quite often use LM4562. Much faster than NE5532 and much more capable to drive "more current demanding loads" but also no "fatiguing sound" at all.

[@arthurrose6473]

Excellent video! You present the same set of op amps I was researching, and you gave frequency response curves, a multitude of music genre, and an artistic, professional presentation! I've watched this video probably a half dozen times because of it's content as well as presentation.

[@tomekichiyamamoto2177]

Thank you for this video.

[@Douglas_Blake_579]

Scale matters! 1:10 ... Measuring the 4558 at 12db of gain (voltage gain of 4) against the 5532 at 0 gain is not a realistic comparison.

[@peterkalmar757]

Interesting Video. But there come some Questions in my mind. Isn't it also a matter of the Design around these Opamps? Arent's these different Input types, like Fet (OPA2132), JFET (TL 072), Biplar BJT (NE5532) CMOS (OPA1656). Arent there different input resistances between these opamps? Don't have some internal Frequency compensated, and some need external compensation? Is it a good idea just to switch an opamp in a circuit between these types? Couldn't it be, that they won't work properly?

Fantastic work! 😉👍

[@mikepxg6406]

It simply depends on the design application. Replacing an op amp is more likely to add distortion as the Equipment you have is designed around the opamp inside. Most people don't have enough electronic knowledge to do this. Every mixing desk in the audio chain has gone through hundreds of NE5532. So you put in an unsuitable JFet OPamp in a little box in your living room, you hear some high frequency noise and think it sounds better because you paid more for it, Unless you can test an improvement you are probably making things worse. Plenty of High End audio use Philips / Signetics NE5532 because they are perfect for audio,

[@ItsMe-mq9tp]

Thx🎉

[@fx-studio]

The NE5532 is an opamp from the 1970's, nearly 50 years old ! Believe me the world has moved on a bit since then.

[@Thoughtflux]

Can you do one with Muses, sparkos & burson v6 too please

[@MkUltra-sk6dx]

You probably don't think he's a naive who will pay that much for opamps that differ only in that they play in class A

[@Zockopa]

Personaly i use 2068DD as replacement for various older low cost opamps in vintage audio gear. Its pretty universal and easy to implement. However,of equal importance are the passive parts surrounding it. Some more modern opamps are clearly better when it comes to noise and THD,but in practice its not worth the investment in most cases. Anyway only opamp rolling doesnt do the trick in most cases.

[@noneofyerbeeswax8194]

"Of equal importance are the passive parts surrounding it". Yes, absolutely. OpAmp rolling doesn't do the trick. You also need gold plated jacks and pure 101% silver cables.😁

[@RickRuizAudio]

Good video 👍

[@MrPolluxxxx]

I'm not familiar with audio electronics. Comparing different chips without mentioning the circuit they are used in is confusing to me. The frequency response of the amplifier changes based on the applied feedback. Is it some kind of standard circuit? I'm sure you're not using the opamps in open-loop configuration.

[@AndrewDelle]

Absolutely! I was going to post the same comments. Those response graphs are useless without knowing the external circuit design. Just for starters, what is the gain these OPAMPS under test? And then doing listening comparisons through the KZbin audio chain?

[@MrPolluxxxx]

@@AndrewDelle it's nice to know I'm not crazy. I hope they are all talking about these opamps in the context of a reference circuit topology, otherwise this whole comment section makes no sense.

[@Douglas_Blake_579]

I can't speak for headphone amps, I never use them. But in the new mini-amps everyone is going gaga over, the ne5532 chips are almost universally used as phase splitters to drive the TPA32xx series chips balanced inputs. Some have a little bit of gain, 3db is typical, most operate at unity gain. At unity gain the frequency response will be that of the chip's Gain/Bandwidth product (AKA unity gain bandwidth) and thanks to the massive feedback used it will be ruler flat. In this configuration both the 4558 and 5532 chips will give you extremely low distortion and perfectly flat response, well beyond a megahertz. In fact, I've seen 4558 chips passing a 6 volt, 1mhz square wave on my breadboard circuits. The 5532 will do it too, but the input impedance is much lower, leading to some low frequency roll off below 10hz.

[@Douglas_Blake_579]

@@MrPolluxxxx The comparison is valid in that chip-flipping does not alter the surrounding circuits... so it is testing different chips in the same circumstance. What is not realistic is comparing the response at 12db of gain with that at 0 gain. (Look carefully at the scaling on those graphs.) Not the same chip, not the same circuit ... no premise for comparison.

[@MrPolluxxxx]

​@Douglas_Blake_579 Yes, that's true. But I dont think it's very meaningful. We don't know what circuit or what device (I don't remember if he says what device he's using) he's flipping chips in, so we only know what difference it makes in his very specific case. In other circuits, it might not even make any difference.

[@you2ber252]

You mean the open loop freqeuncy response, of course. And what about the slew rate and the noise shae... However to my hifi experience, NE5532 with reasonable negative feedback is fully transparent in the audio band.

[@wakesfield]

For me the JRC 4558D has the best sound, for me the most natural and dynamic sound. I have listen to this in a acoustic treated room with expensive studio monitor.

[@SzalonyPirat-b2r]

[@2jpu524]

We're also at the mercy of the you-tube compression algorithm.

[@xfloodcasual8124]

Theres no issue with KZbin compression anymore. it can stream 96Khz if you encode correctly.

[@TranscendentBen]

1:11 These graphs are totally made up. Here it shows the NE5532 with 0dB gain at 30Hz (the left-hand portion of the graph, why not 20Hz like True Audiophiles would want ...), but the JRC4558 has a gain of over 12dB. These would have to be in different circuits for this to be true, so it's clearly not a valid comparison. Sorry, folks, you need to learn a minimum amount about electronics to have a clue what's true and what's not.

[@Douglas_Blake_579]

Yep ... absolutely correct.

[@TTVEaGMXde]

I wouldn't even use the 80s Op Amps as an offset servo anymore.

[@AstroSam66]

Could you please tell us why?

[@TTVEaGMXde]

@@AstroSam66 4558 is much too slow, 5532 input resistance min = 30K Ohm, 2132 and 072 are FET OP Amps which are usually only tested at 2K Ohm or less load (no 600 Ohm load) and tend to produce even harmonics that sound "nice" but not original. The input noise is much higher, and very high at 40 Hz.

[@AstroSam66]

@@TTVEaGMXde The higher the input impedance the better. There are not much OpAmps which can drive a 600 Ohm load (NE5532 or LM4562 e.g.) If the OpAmp is not capable to drive 600 Ohm, you could always use a Unitygain Stage as follow up. And most of the time, driving a load of lesser than 2k is not necessary because the input impedance of Audio Equipment (besides of Studios) is always higher than 2k.

[@TTVEaGMXde]

@@AstroSam66 However, a larger output resistance is required to avoid oscillations caused by the cable capacitance. The feedback path must be built with very low resistance for low-noise applications.

[@AstroSam66]

@@TTVEaGMXde What are you trying to say? At first you blame OpAmps to have a too high output impedance, then you say you need a high output impedance. The resistance of the feedbackpath has to be as low, thats right. But has nothing to do with the OpAmp itself. It is caused by the Johnson noise. BTW: you already did not tell us why the "older" OpAmps are not as good as new ones.

[@ChipanJana]

Your audio is too quiet. Cannot hear you properly above a normal road outside. Can hear everyone else on youtube fine. Ipad pro maxed out.

[@ChipanJana]

And the fact that you think people will be able to tell the difference between these op amps WHILE THEY’RE LISTENING ON DIFFERENT ONES means you’re not to be considered. Channel blocked.

[@zarkoujdur9424]

JRC4558 is very old opamp, and prefix JRC means nothing, it is a just generic 4558 opamp, afaik... ))

[@Douglas_Blake_579]

The chip is an RC4558 ... made by a number of companies with NE, LM and other brand prefixes. It's still around and it's dirt cheap because literally millions of them are sold every year. The J prefix from ArtChip indicates it is 22 volt tolerant where the standard chips are only 15 volts.

[@qddk9545]

This is a completely misleading video. NE5532 and JRC4558 are really low fi op-amps, designed more that 50 years ago. At the time NE5532 was the best op-amp out there, but that is a very long ago. Try to feed it with a square wave and you will see that is is ringing like a bell. Compared to for instance a LME4562 it is complete junk, and discrete op-amps are even (much) better. I hate that people who don´t know better, keeps promoting such a shitty low cost component. Try to listen with your ears, not your backside, and you will hear that NE5532 can ruin every audio signal.

[@MkUltra-sk6dx]

5532 ruins everything, so listen to music created and processed on these opamps in professional recording studios😂😂😂

[@noneofyerbeeswax8194]

It's a good thing audiophools don't know how many hundreds of opamps the signal goes through before even reaching the most sacrilegious thing known to man: ADC. Most of those are 5532s, LM833s and NJM4580s. Sometimes even TL074s. Perhaps it's the superconductor cables that let you hear the difference?
