How noticeable these differences are and whether the differences are good or bad depends on your specific application (RIAA equalizer, line driver, tone control, post If I'm in the mood for that so called "burr-brown" slower lazier sound I prefer the OPA2228 but as with my comments about the AD8066 below you can't just drop that into any old circuit and get good results - the OPA2227 is a more drop in replacement but doesn't sound quite the same as the 2228. But even though I replaced it in my previous (2 in) A07 or mixed in A07Pro, the real sound experience doesn’t match sound quality vs cost I spent for a budget product like Aiyima . Its high slew rate and wide bandwidth make it a go-to choice for audio processing, ensuring that the magic of In the review of the Fosi V3 (Fosi Audio V3 Amplifier Review), Amir wrote “There are replaceable op-amps for those of you who have nothing better to do than mess with the design. It ensures a very low noise density as well as an extremely low distortion level. 1nV/√Hz at 1kHz bipolar-input operational amplifiers achieve very low • ULTRALOW DISTORTION: 1. I had read it many times before posting this threat. LM4562 and LME49720 are the exact same part just different model stamped (stated by an ex-employee) The LME49860 is just a Check for Samples: OPA1611 OPA1612 1FEATURES DESCRIPTION 23• SUPERIOR SOUND QUALITY The OPA1611 (single) and OPA1612 (dual) • ULTRALOW NOISE: 1.

Sound-stage increases, sound becomes more detailed without being harsh or sounding bright. The OPA1641 would be slightly better. TI-Produkt NE5532 ist ein(e) Rauscharmer Zwei-Kanal-Operationsverstärker, 30 V, 10 MHz, für Audioanwendungen. Bluebook The right price. By the way, the NE5532 tended to worsen easier than analogous* BJT input types I tested when in G=10 non-inverting mode. Sound: For purposes of these tests, I started out with a Burson Swing and Fun DAC and amplifier. Dear sir, in my amps, I have NE5532AN as input (right after the rca plug). Check there is HF decoupling on that chip first オペアンプの違いによる音質比較表を、店主の主観たっぷりに紹介しているので、オペアンプ交換の参考にして欲しい。 Other Parts Discussed in Thread: OPA1612. Better than any op-amp in terms of transparency except their own V5 ofcourse. OPA1656 sounded worst, Muses 8920 sounded best. I am looking for a dual version of AD797 for replace the NE5532. ) The next op-amp I am planning to try is the OPA1612 but perhaps the DAC is the limiting factor and perhaps the measurements will look very similar to the OPA2134 even if the OPA1612 is a really good op-amp. The NE5532 was clearly the worst sounding when listening after the clearest melody pitch, but one could be very lost in the evaluation If only listening to ” the sound of the music” - not - NE5532 - Burson V6 Vivids - Sparkos SS3602 - Sparkos SS2590 - Muses 01 Of course it's all about synergy with the rest of your audio chain, but testing in my Burson Funk I preferred: SS2590, SS3602 and MUSES01. Looking to buy some opamps for rolling then stumbled on a thread with people saying that the three are the same thing. So, it is a different design and chip. LM4 is even better in THD, but shows signs of instabilities. The new OPA1622 delivers lowest distortion and noise, high linear output current, and low power, enabling the highest performance for professional and The NE5532 should and can sound very transparent when used correctly and in the right applications, however, I read an interesting article on the 5532 and how its bjt input stage can give rise to odd distortion products when used at the output of DAC's due to the residual HF hash causing non linearities. 000015% at 1kHz. It is the question whether this is still so. 1 IIUC the folks at Sparkos designed the board for Allo or they collaborated on it. Looks like the unit was powered by 60hz bench supply but used in a 50hz environment. NE5532, NE5532A, SA5532, SA5532A www. Even for audio use there are a lot of different applications like - line stage low gain/unity gain (buffer) - line stage, high gain (microphone amplifier) - RIAA stages with RIAA in the NFB network - power amp front end (two versions - signal pad by output and by power supply rails) - two version of low pass/high pass stages in active crossover Curiously enough it seems to sound its best in combination with the OPA2134. Status This old topic is closed. Touting sound quality in the datasheet makes it sound 300% better. One relevant point is that the supply voltage as shown is about +/- 6. It (in its present-day format of the NE5534) has remained at the top of audio quality ever since. Two cases were evalutated – in a Breeze Audio AK4495 based DAC, driving a ATHA5000 amp (listening via Beyer T1’s), and then driving a Grado RA1 clone (basically a CMOY circuit) to hear the amp The sound quality comes from the entire circuit, not the op amp. Virtual Systems. Noise is roughly around 3-4nV. Hello. Lm4562 3. The easiest is the 2134, but the 2107 and 2134 combo are huge leaps in the quality of sound.

I am amazed at the sound quality of these little things as it is, I never expected them to There's are reasons people use NE5532's and JFET opamps, and low current-noise is a notable one. Overall balance with new amp is a little darker but with better transients. Same opamp could sound more open and with a darker background when tested in equipment #1, but may sound with a much closer scene and with a bit of hiss-noise when installed in equipment #2. g. 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. 3. Unfortunatly with the new OPA1612 I have obtained a lot of noise on the output channel. Both devices However, swapping opamps seems to be more dependent on the surrounding circuitry, their quality and PCB layout, than the opamp itself. The idea is A fair question! And although I was the product definer and systems lead for this part, I don't get 100% control over the marketing folks But, I can honestly say that when we started working on this part about a year ago, I was very adamant that I didn't want to create a part with excellent specs but terrible sound quality in the real world. the ne5532 looks a bit harder, narrower and more direct, the other two a bit more relaxed and further. I did not EEVblog Electronics Community Forum » Electronics » Projects, or otherwise LM833 and NE5532. There is a site where some types are tested. the differences aren't huge, but big enough to make a change worthwhile. If possible, you could try all of the three op-amps from above without getting worried to get oscillations. This is a thread were we discuss subjective sound results, meaning one can prefer a colored dac . Does it SOUND better? I don't know. Joined Sep 8, 2012 Messages 848. Technically speaking, it's really hard to beat opamps like AD797, AD8599, OPA1612, OPA1656, so it might be safer to use one of these over the "exotic" ones, Try a pull-down load to the negative supply rail to force the NE5532 into class A, just a few mA will really make it sound better. Forums. Slew limiting at audio frequencies, especially for relatively low Lets take a look at the NE5532 op-amp, used in audio products everywhere since 1979 and it costs about a $1. It features an advanced integrated Hi amigos, I share with a quick review of an unknown new DAC. 3- Overall would you recommend the AIYIMA A07 or the Shui Yuan board? I don't care about the casing, The Vendor's Bazaar forum is for commercial offers and transactions. The designers thought it would be a good idea to add 10 μF to the 0. Hello together, i want to put one of the mentioned OP Amps in my amp. So why does TI think the additional 10 μF is necessary? Building an audio power amp based on Yewen's idea will provide only a marginal performance improvement (if at all) over other loop gain increase techniques. The stage is huge and provides a well spread instrument distribution. Featured Vendors I was wondering if the OPA2604's could be replace with a dual opamp like the OPA1612 with similar or hopefully better results than the OPA627's? It can be replaced but you'll get diferent sound character. TL072 have low current output capability. Sparkos was total disappointment. These three Op-Amps sounds great. Douglas Self advices not to bypass them to ground. Personally I find running op-amps in class AB a bad idea since this inevitably creates crossover distortion and it is entirely up to GNFB to reduce this ugly kind of distortion, and GNFB becomes less effective in the higher frequency range. I've had an OPA1612 lose its mind in a filter circuit where an LME49720 worked just fine. 5 Electrical Characteristics VCC± = ±15 V, TA = 25°C (unless otherwise noted) PARAMETER TEST CONDITIONS(1) MIN TYP MAX UNIT TA = 25°C 0. If you want to reopen this topic, contact a moderator using the "Report Post" button. You must trade-off the distortion and S/N ratio. The OPA1642 has the JFET input stage- thus reducing the input current noise- reduced common mode input distortion and sensitivity to source impedances, and lower standing Hi All, Please advise what would be the best bet for a modern replacement of the NJM353 in my 12-15 years old vintage 4X60W Class A Zero Feedback car amplifier? Tried dual OPA627AU on adaptor but the sound is of reduced volume, of loss details and PCB is warmer than before and the noob in me did not realized the input current of The OPA1612 does not seem to have the process contamination of the LM497X0 that produces rocky-sounding noise. In terms of pure sound quality and power, is there a difference between the A07 and the typical AV receivers or stereo amplifiers from brands like Sony, Yamaha, Denon, Marrantz, etc? Archived post. Excellent ampli OP Utilisés en remplacement des NE5532 dans le kit préamplificateur Velleman K 8084, ils donnent We tried OPA1612, OPA1656, NE5532, and Muses 8920 opamps in Rohm BD34301EKV Evaluation Board (which came with 5532's installed). OPA1612 is decent the only reason I'd use Texas Instruments' OPA1612 (dual) bipolar-input operational amplifier achieves very low 1. Just to mention a few: Show hidden low quality content. Only really better substitution for NJM4580 for example as Pre-Amp can be no less then OPA2228 or even better OPA1612, but for that -3dB less noise (and distortion) over whole audio spectrum you will have to play premium extra. Conclusion. If you really feel the need for something faster, look at ADA4898-2 or ADA4896-2 (+/-5V supplies max). Because the first one has to do with emotions. alongside with some aliexpress el`cheapos for like 2 buck a piece instead of 7. The OPA1642 is significantly inferior to the OPA1612 in many regards (GPW product, output drive, distortion vs output load, input voltage noise for example). The NE5532 is, of Sometime I use OPA1612, OPA1642 and OPA1622. Attachments The OPA2228 didn't sound good in the DAC, and was the least good in the op-amp gain stage. Merch Rep the community and hobby you love so much. Can I replace NE5532 opamp by two AD825 on a kind of browndog dual DIP8 pcb adaptor? And can I replace NE5534 opamp by one AD825 on a DIP8 adaptor? I hope to enhance sound quality, of course. The NE5532 is a bit better than the LM4562 for NE5532/34 is the best op amp for audio. I can whole The NE5532/5534 opamp The 5532 is a low-noise, low distortion bipolar dual opamp, with internal compensation for unity-gain stability. It is the best $1 opamp you can get! Sure, there are opamps that perform better spec-wise---the LM4562/LME49720 is the best PDIP-8 available, only surpassed in the bipolar world by the SOIC-only OPA1612. The xlr input and the trigger are two great additional features, as is the nice and efficient enclosure, however the mono is not true mono, and the 13 db of sinad lost is a bit disappointing, especially given Some will point out the OPA1612 (which is even better) or the OPA1656. (Leaf Dac Dual 9038Q2M ) This DAC is using a dual 9038Q2M chips and fully balanced and also equipped with DIP8 OP amps and removable BT module. The world's largest high-end audio community. 7 nV/Sqrt[Hz] vs NE5532 with 5 nV/Sqrt[Hz].

Let the world see what you've built. 50 each only six months ago. 1 nV/√Hz at 1 kHz of ±2. Before any modifications I use shematics to see what i need to choose between these four Op-Amps. edit: looking closer at the pics, the I/V resistors are 390R (about half the datasheet values, which makes sense as they // the outputs). 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 The OPA1641 would be slightly better. OPA1612) - quite popular in higher end consumer devices - i tryed lme49722 opa2134 and opa1612 ,--. General Audio Discussion . V6 vivid measured superb tho. After several hours of testing OPA2209 vs OPA1612 my subjective conclusion is: When you would count the points in the categories (i. Featured Vendors I tested for a few hours and is quite similar with the NE5532. com/blogs/news/opa2156-hifi-in-cmos. Previously I did some changes especially in all technical aspect and evaluate the sound My choice would be OPA1612 oder ADA4898-2. Virtual Systems Let the world see what you've built. Although NE5532 performs well, many audiophiles still want to improve the sound quality by replacing the OP chip. - high levels of DC precision are generally not required by audio customers (audio equipment makers). It features an advanced integrated feedback design and I bought 100 NE5532's for the same money, and the MUSES02 is basically about the same as an NE5532 without the high current handling I think. the best sounding is OPA1612 ,not for driving headphones -low output current drive ,3ma current consumption ---then opa2134 the best all around as preamplifier it can be used at high gain 6-10 times,very good sounding and Musical,good for biassing in class A. It is nice to discuss theory but in practice Currently, the op chip used on AIYIMA A04 & A07 is NE5532. ••• NE5532 ADA4898 LM4562 LME49860 OPA2134 OPA2604 Please feel free to suggest other models.

Who knows what Search titles only By: Search Advanced search G'day all, last night I was about to place an online order for some NE5532 op amps from my usual online supplier but I find that they list several versions of the NE5532 ((NE5532AP, NE5532P and probably others!) The specs all look the same but there is an appreciable difference in price between these two items! question 1: I was looking at the NE5532 datasheet and I can see typical supply current is around 8mA. When the original OP is Bipolar(like NE5532 etc) we can most always replace with FET or another similar Bipolar OP. The OPA1611 (single) and OPA1612 (dual) bipolar-input operational amplifiers achieve very low 1. Bass is also fairly one-note and lacks a bit of impact, and each instrument sounds less distinct in the 5532’s congested stage than they do with better op-amps. IMHO the outcome was mostly decided by how the opamps responded to the RF coming out of the dac chip. Although I am a fan of the OPA2134, I still have very considerable respect for the NE5532. To my experience, Yewen's technique is effective for fixed gain, inverting, composite op The OPA1611 (single) and OPA1612 (dual) bipolar-input operational amplifiers achieve very low 1. 1 OPA1612-Q1 SLOS931A –NOVEMBER 2015–REVISED NOVEMBER 2015 OPA1612-Q1 SoundPlus High-Performance, Bipolar-Input Audio Operational Amplifier • Superior Sound Quality These devices operate over a very wide supply range • Ultralow Noise: 1. 5a to replace my current 48vx5a for any change of improvement.

When we developed the OPA1656, this was also a major design target for us, and the designer and myself spent quite awhile in the lab with previous CMOS audio op amps (specifically Only the sound quality should be always the most important thing. 2 things I have noted from looking at the circuit board so far: 1. I have some vintage audio gear that I would love to keep period-correct, but the price surely has sky-rocketed. Every time. I hesitate to recommend those without simulating the circuit. Bat boy-o-boy they sound so GOOOD on all of my studio speakers and headphones (starting with old The original NE5532 2. OPA1612 is Opa1656 and opa1612 without tweaking have better performance than almost any discrete solution. -Category Forums. I'd suggest using NE5532 or OPA1612 for U4 in the first instance and see if that's making a difference. just as an example of bipolar NPN input opamps , like the OPA1622 , or AD797, NE5532, OPA1692, Anyone know whether the LM4562-LME49710-LME49860 series are PNP input or NPN . They are doing just fine for almost all needs. If a transient causes the op amp inputs to be pulled apart, the differential input voltage forward-biases those diodes causing a large input bias current. The output swing for Aol should be considered as it is different between the two devices. According to the TI datasheets OPA1612 has less noise than OPA1656. But to take advantage of this, you need to ensure that the Johnson noise of the resistor network you are feeding the input from is small, which for such a low input noise voltage means you are in the low kOhms. It has the most stable input capacitance vs. Marketplace Home. so you are steering towards the 1642, and you find the 1602 and 4562 about the same in terms of sound? Caps on the dac supply pins.
