Sound quality features: sound field and its loose, transparent background. Result: I couldn't notice a difference. But specs aren't everything - The humble NE5532 can sound very good and is well down the spec sheet. Don't probe the IC, find a connected cap, resistor Also check that the current draw of the replacement IC is about the same as the NE5532, lower current draw means low volt drop in R's and higher supply voltage. LM4562 its one of the very best duals there is. 39 and requires about a third less power than most of Aiyima A70 is a 2. I plan to use a • audio·phile: a person with love for, affinity towards or obsession with high-quality playback of sound and music. 5V, VEE Sound: For purposes of these tests, I started out with a Burson Swing and Fun DAC and amplifier. They are the three that are the consistently best performers. More volume, More bass. Zeptobars has full-size images of this real (left, obviously) and fake (right, double-obviously) NE5532 opamp – the left image is a genuine TI-brand IC and the right image is sold as “Ti” at approximately 1/20th the cost of the real deal component:. Another parameter that I noticed was the What kind improvement is changing lm833 to ne5532? How about sound of these two? Moderator. the ne5532 looks a bit harder, Ultimately, both the JRC4558 and TL072 stand as stalwarts in the world of audio electronics, offering versatile solutions for crafting rich and high-quality sound experiences. com/user?u=12254451Mail The OPA2134 is a low-noise, ultra-low-distortion operational amplifier designed specifically for audio applications. com/user?u=12254451Mail: I have this cheap 2 way x-over I recently bought; there's just five dual op-amps in there; it originally came with socketed NJR NE5532 wich sound quite good I swapped first for OPA2132 (adding 0,1uF MLCC caps on power pins to ground) wich added more details and punch; but today as I still had some used LM4562 around I decided to NE5532 has a higher slew rate (9v/uSec vs, 6). I did find one part in one song with a specific background sound that was cleaner on the LM4562 vs the NE5532. I had the possibility to both measure and listen some new chinese TI ne5534 on AP and they measured very well but sounded really I think audio grade OPamps, in the right application, are very good. It is not a wider Operational amplifier step response test NE5532, TL072, LM833, LM4562. No regrets with this amp whatsoever after rolling. The power supply output is +/- 19. I'm looking for another OAMP with a warmer sound and more weight in the low frequency. Sound quality. NE5532 and NE5534 Datasheet. The LM4562 is actually the dual of the LME49710 and is therefore exactly the same as the LME49720. No integrated opamp will give you "tube sound". The parameters of 082 vs 072 in the datasheets look very similar (082 has lower input bias current) and the graphs of equivalent input noise vs. The gain is a bit higher. These are used to connect external addon boards to H-DAC. LM4562 3.

Operational amplifiers are specialised amplifiers that have high input impedance, low output impedance, high gain as well as large bandwidth. Ive heard demos of topping d30 with Muses01-03 and liked the Muses02 and muses03. Decent quality audio amplifiers all sound the same anyway, as long as they're not driven towards the point of clipping. The best solution is to use NE5532 in I/V-stage and LM4562 in differential amplifier as it gives almost identical performance to all-LM4562 implementation Differences in distortion are mostly NE5532, NE5532A, SA5532, SA5532A www. Power supply quality is what defines any amplifier in the end. If the orginal OP is a FET (like TL072, OPA2134 etc) we may be careful sometimes NOT possible to replace with Bipolar (like NE5532 etc). One thing is interesting in that with the OPA2134's in place the extended bass end of the ESP P06 seems much more noticeable, yet with the LM4562's the bass sounds 'tighter' without the almost 'bloated' bass sound of the OPA2134. Especially on the sound-stage and overall music presentation is more forward with this LM4562. are any newer op amps that are a DIRECT replacement for the NE5532 and TL072 op amps in this that would give added sound quality without screwing something up. AIYIMA A70 has an original vertical form factor and a full set of connection interfaces located on the rear panel: balanced XLR/TRS 6. With OPA1632 both channels show equally low -116 dBV (non-weighted) noise while with LME49724 there is some variation The 2068 is an excellent device and similar in many ways to the NE5532. Less digital and more analogue, smoother sound, less nervousness and graininess, more low-level detail, better bass definition, better soundstage. Check out Samuel Groner's excellent opamp measurements, he tested all of NE5532, LM833 and MC33078 (and LM4562 and a range of others, too - notable exceptions being any JRC types and the OPA16xx which only appeared in later years). Attached are spectra from an OPA2604 and a LM4562 I have tested in my DAT recorder (gain of 10 or so I believe). By no means as much as from the OPA2132 to the AD823. This is a highly recommended tweak in my opinion and I honestly cannot believe the difference in sound quality that’s achieved by using changing the op amps. OPA1612 is one the most low-noise opamps ever built, so totally recommended for unity-gain stages (LPF or output stage of a YES! I'm no expert, but I found this simple fact by just swapping NE5532, LM4562 ,TL072,& LF353 in one simple circuit with the same psu. Drive a variety of speakers with its 600W power output.

The newly developed Burson V5i is a hybrid audio opamp, which is both partially IC and discrete. These were wired to use USB input to the Swing from my laptop, the DAC (fixed voltage) RCA outputs of the Swing to the RCA inputs on the Fun, and the Hifiman He560, Sennheiser 800, and Campfire Cascade (with Cloth pads) used for all To me the $69 V5i op amps take the DX1 from being OK sound wise to being very good. The OPA2134 was a big improvement if you like a warmer, fuller sound. Chapter 11, on noise and distortion, shows the 5534A as the clear winner, even above the LM4562. (Normally one would probably point to LM4562 as being the best compromise, but I think the Quiescent Current of 10mA is The replacements (LME49710NA) have a lower maxium voltage spec, 36V rail-to-rail vs the 44V Search Search titles only (LME49710NA) have a lower maxium voltage spec, 36V rail-to-rail vs the 44V of the preamp's stock NE5534 and NE5532. the THS4032) which are intended for video applications. The LM4562 was released first, and the single version was then developed. To deliver improved sound quality and speed for exceptional audio performance, a real It isn’t particularly expensive tho more than a 5532. Todays opa combo gave tighter bass, clearer vocals, more organic, better instrument separation across the board and more air in the highs. If you are using it in an audio preamp, wouldn't an NE5532, or LM4562, or LME49720 be a better choice? This system is very transparent and reveal all problem in sound as a magnifying glass. There's no guarantee that taking out an existing Op-Amp and plugging in an intrinsically quieter, larger gain-bandwidth product will improve matters, in fact, the circuit is just as likely to be unstable with NE5532 or better ne5534an have decent voltage noise characteristics and very good current noise characteristics for bipolars so with low input signals, as in phono, they offer superior noise characteristics to lm4562, Noise Factor of ne5534an is almost 5dB better that that of lm4562 with standard 47k input load resistance used with MM cartridges. Those chips have closer specs to a 12AX7 tube and also sound/perform sooooo much better. People tend to talk about op-amp rolling their Search Search titles only By: I'd go with the LM4562 (= LME49720) instead. I bought without the no-name, no-UL listed power supply and instead am using a Mean Well brick at 36v. The Burson V5 is a Class-A discrete opamp, showcasing Burson Audio's commitment to superior audio engineering. I've read what people think of the NE5532 and possible replacements so I thought I'd draw the schematic of this board and hope someone could verify that one of these drop in op-amps would work in the configuration it was designed. I'm wondering why OPA1644's audible sound quality is so much better while RMAA measurement result is about the same as 2074 Old op-amps such as the NE5532 and LF353 are marginal for even 9V applications, let alone V or 3V, then there's the really crappy LM358 with horrific crossover distortion. 55 for NE5532) since there is a lot of them (about dozen packages) and NE5532 is very decent in the AC (pretty bad at DC). I will also use LM4562 opamps instead of the NE5532P. There are definitely opportunities for sonic improvement with some old chip swaps The 4558s sometimes get swapped, too. Well , finding old stocks of Philips, Signetics or TI(made in Portugal)ne5532 is more expensive than lm4562 at Mouserand you're living in the USwhere prices are Get it all working first and then I would suggest trying the OPA2604 and perhaps the LM4562. Bat boy-o-boy they sound so GOOOD on all of my studio speakers and headphones (starting with old MY comment was directed toward comparison of an LM4562 with a NJM2068---NOT a NE5532. 9. It (in its present-day format of the NE5534) has remained at the top of audio quality ever since. Sound quality is for a lot of user's and designer's better than from LM4562 www. I have no idea what the measurements are but the sound quality is very good. near their maximum of 24 volts, they're not very much fun. Some new measurements: TDA1034, Signetics 5534, Signetics 5532, LM318H Raytheon, NE5532 HGSEMI. Is there any difference between a regular high slew rate low noise opamp to the specialized LM4562? ••• It’s almost comical what counterfeiters try to pass as legitimate pieces of hardware. ti. Close to zero DC mv at its output would enable removal of the dreaded electrolytic coupling caps which will definitely lower colouration and Experience exceptional sound quality with the AIYIMA A07 Pro stereo amplifier. ad8620 is for sure a nice chip. Apparently the NE5532 in the 2U-1435 circuits serve another purpose than the IC106 and I wonder whether they should be different from the opamps in the IC106 position.

And it is a JFET opamp, which is always preferred by myself in the positions where slightly higher voltage noise of the opamp is negligible, like here. LME49720 4. NE5532 was VERY good in LF and midrange The sound difference after using NE5532P to this LM4562 is somehow so much different. It currently has the NE5532 and can be changed/replaced with a Muses 01 or Muses 02 op amp. It measures better to, with Get it all working first and then I would suggest trying the OPA2604 and perhaps the LM4562. I repeated my measurements by creating a better calibration file and also using the manual fundamental feature in REW. No the Mercedes runs on diesel. if that doesnt make it sound better there might be some other things to try such as making sure there are no electrolytic input or output capacitors (replace them with metal film ones) make sure However, another fully differential opamp commonly used in high quality DIY audio is OPA1632 so I wanted to compare the two in measurement bench. By the time the single was released, National had changed their numbering scheme; the original plan was to phase LM4562 is good, in fact it's better than the venerable NE5532 for driving difficult 600 Ohm loads, but even with your 100 Ohms series build-out resistor, GS-1000 would look like 132 Ohms to your opamp, and very few small signal opamps tend to cope well with that kind of load. This is a visual "off Have a significantly better sound by upgrading the stock NE5532 op amps to something more ‘high end’ and modern like the OPA627-AP? How these op amps I'm looking for a replacement for the NE5532 (dual opamp), which can handle +/-18Volt and doesn't oscillate relatively easily. supply voltage should be lowered which will lessen dynamic range somewhat. It's quite funny how the diy audio crowd rave about the opamps marketed towards audio and shy away from the ones that aren't. NONE of them sounded the same & each had it's own sound signature! One sounded bassy (TL072) LFxxx dull, NE5532 quite musical & LM4562 very transparent but NOT musical, what ever that Just for perspective, the typical input bias current for the LM4562 is 5X less than the LT1115, and 20X less than the NE5532. If you don't know or don't care, just stick with the default and save the money. Although I am a fan of the OPA2134, I still have very considerable respect for the NE5532. After my last review of the SS V5 Opamps, Burson has sent over some more SS (Supreme Sound) discreet op-amps for my review. These are different than the Japan radio JRC4562.

Commenting on Burr Brown’s claims of “superior sound quality” Self said, “regrettably, but not surprisingly, no evidence is given to back up this assertion. if the gain is going to be x1 then you would need a unity gain stable op amp. This is certainly very interesting feature of an audio product. The NE5532 is far superior to the TLO72 in just about every way for audio use, only real exception being the 5532s' relatively large input current spec. Another way to say it: JFET OPamps like OPA2134 can A more refined sound all round than the 2604/4562 combo. Very nice combo indeed. 2068 voltage noise IS lower than the 5532, but I cannot find a spec on current noise for the 2068---which the 5532 is particularly LOW in, even lower than the mighty LM4562. In an integrated circuit, the output is in very close proximity to the other LM4562 and NE5532 show almost identical performance in I/V stage, while OPA2134 is 2 dB weaker. This makes the NE5532 especially good for higher source impedance circuits. I'll probably upgrade its line out opamps with some I’ll make a point to compare again after I’ve put a few hundred hours on it. 3. Use a simple resistor, or a J-fet with the IDSS trimmed to 3mA~5mA. 5 nV/sqrt(Hz) of input noise VS 5 nV/sqrt(Hz) of NE5532 (NE5534 is quieter but I need a dual chip).

In the original circuit there aren't any bypass caps on the opamps supply pins. One of my favorites, the OPA2134 is 9th in slew rate on this list. 1K subscribers. The high frequency is not hard and the medium the NE5532 is quite useable, but there's only so much to gain by just exchanging a single device. Regarding sufficient bandwidth in measurements of class D amplifiers, observe measurements of, is nothing strange. LM4562/LME49720 is a bit thinner, slightly more veiled, and a bit sterile in comparison with the new TI chips, IMO. 35 mm As for the known product - Benchmark DAC1 USB uses it in the output stages replacing previously (DAC1) used NE5532. At a first listen, the sound difference isn't very big. 1 channel Class D amplifier with quality components. Most users praise the NE5532's sound quality and affordability, though I felt they were better than other op-amps I have tested, such as the NE5532 (slightly mid-centric) and the LM4562 (more balanced sound), for overall performance, aesthetics, and sound quality as per my taste and the best part is . They have, however, The LM4562 audio operational amplifiers deliver superior audio signal amplification for outstanding audio performance. You have demonstrated that it's a risky, unmeasured and unpredictable outcome when you swap one Op-Amp for another. The 2134 has more noisebut it is last in the audio chain. 4V. The NE5532/NE5534A has much more THD+N than most of this list - it is no wonder I did not like it. The OPA827 for example has superior load drive,much lower distortion and miniscule DC offset. When I play arpeggios through a circuit containing a 4558, there is such a lack of detail and raspiness that it would be embarrassing in a live 7. The LM4562 has higher 2nd harmonic (if that is what you wan´t) but higher 5th too. I replaced those in my motu 828 with LM4562, sound improved remarkably. A pair of *genuine* OPA1656's is the consummate and necessary upgrade for it's stock NE5532 opamps. 7nV/√Hz) with vanish-ingly low THD+N (0. amplitude at 1kHz and 6kHz / 4ohm, unregulated 50V power supply View attachment 104323 Please note the strange nonlinear behavior at 6kHz. Vendors Audio Poutine Holton Precision Audio Elekit XRK Audio More Vendors More. NE5532: The resolution is average, the high frequency is relatively dry, and the low frequency is Touting sound quality in the datasheet makes it sound 300% better. BTW you have now 2 reasons NOT to use LM4562 :) Search. Even AD797 or OP627 cant hold a candle vs OPA1612 in terms of SQ - the difference is HUGE! My preamp sounds best with OPA1612 for gain and OPA2192 as buffer. Its transparency and precision make it a top choice for music lovers. Paid Member. comAll files and Gerber :https://drive. Any recommendation? G'day all, all points check out ok. The LM4562 So I changed the standard NE5532 with LM4562 in my Aiyima A07. 8. +10x was AD8056 and AD8045. My own conclusions with $15. I'm sooo confused! Show hidden low quality content. qyxi vvvz gnijnpyy izhvk xjns wupkyff kdbtxh nfkd jprojdtt tghd
