Opa1612 vs lm4562.
Something better than the LM4562? I want to change LM4562.
● Opa1612 vs lm4562 OPA1612 ~ 6 Euro According to specs I would think the OPA1642 would be one of the best compromises cost vs performance wise. Thread starter rhythmsandy; Start date 2012-08-24 7:28 pm; Status Not open for further replies. Now we're talking! Detail, soundstage, imaging, wow! Only downside is a definite reduction in midbass punch. My perfect sound would be the 1612's with the bass of the 2132's. I doubt anyone would ever be able to hear the difference between any of these in a blind test. Over this supply range the LM4562’s input They are "better' ones you can try - LM4562 is always a good candidate just check the supply voltage fist. May be 828 will be better, but i have to do some thing in the board to extract best of it. Last edited: Jan 3, 2023. 000. DACのオペアンプを交換しました。線が少し細くなりましたが、小音量で全体のバランスが良くなり高域のクリア感が増しました。SOP8パッケージの交換は面倒なので、最後にすべくOPA1612に変えちゃいました。SOP8をDIP変換で交換出来るようにとも考えましたが、安定性を考えて中止です。 So, did some research and ordered up OPA1612's with SOIC Adapters. Weiss. « Unless you consider the OPA1612, LT1028, LT1115, 1N A217, or the THAT 1580---which are ALL quieter in a phono stage. The OPA1642, SMT-only, is also a The LM4562 datasheet indicates it has at least 12dB greater open loop gain than LM833 at all audio frequencies. I designed and built a battery-powered preamp around the LME49720/LM4562. I rolled the T6 Pro with the Oracle 02 op amps in the preamp output stage and the opa1622 in the A07. Maratnz likes to drive 5532s with the full swing of +/-22V which is too much for most of the stock replacements. • Power Supply Voltage Range: ±2.

Jump to Latest --lme49722 lme4562 lm4562 opamp is very good sound ,higher ratings than opa2134 -but not as warm and musical (recommend 2134 for driving amps) high current drive,enough The OPA1612 is more robust against EMI than the LME49720. OPA1612 is one the most low-noise opamps ever built, so totally recommended for unity-gain stages (LPF or output stage of a DAC, but also I/V stage too). In my experience any audible difference between well set up opamps is fairly subtle. the LM4562/LME49720 and the OPA2134. Post #6,064 of 7,422 nesty 100+ Head-Fier.

A more refined sound all round . diyAudio Community diyAudio Store. if you like it then it might be worth considering 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 Used OPA1656 in I/V of PCM1792 in dual mono configuration. the sound difference was what I imagine rolling a tube sounds 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. tnt-audio. (Normally one would probably point to LM4562 as being the best compromise, but I think the Quiescent Current of 10mA is very high) OPA1656 has even lover distortion. IMO, the ADA4627-1 has a fuller, more "musical", sound than the somewhat thin/sterile LM4562, whilst still retaining nicely detailed highs, and remains my favorite sounding op amp to date. The OPA1612 does not seem to have the process contamination of the LM497X0 that produces rocky-sounding noise. All five op amps have more than half the noise compared to the NJM4560. The sound is very different between them. Nonetheless, I already like it and I think its a better sound than when the 1656s are in the soundstage preamp. Really only matters if you are doing 24 or 32 bit designs for specs only. LM4562 is more punch, dynamic sound and it could oscilate very easy, you must be carrefully with it, LME49860 it has a more warmer sound, sweety treble, but the midrange just a little in the back of stage and the bass is more soft, not too good. If you want discrete, then Sonic Imagery 994 or the Weiss op amps. The sound is smoother/refined and more listenable. Valid comparisons between amplifiers can only be made by a double blind test. Though the diff when using it further down the chain in the amp is lesser than in a preamp. OP . Especially on the sound-stage and overall music presentation is more forward with this LM4562.

Something better than the LM4562? I want to change LM4562. Thanks in advance. #1 Choose the LM4562 (LM4562 vs NE5532): High-End Audio In the case of my two Aiyima a04 and switching between ne5532 amp to lm4562 amplifier, the difference soundwise is clearly bigger than moving your head 30 cm in the listening room. Average dimensional soundstage. com/blogs/news/opa2156-hifi-in-cmos. Buy and try several. Long-winded question for anybody is what’s the diff between these The amplifiers you mention have lower input voltage noise, but when their input current noise is taken into account, when working into typical moving magnet cartridge source impedances, the total noise of the phono amp circuit is not necessarily lower. 5 V to ±24 V) Equilibrate warmish!

The sound quality is quite reasonable unlike most YouTube audio demos And what about low voltage applications? 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. Jun 11, 2018 at 9:36 PM. Probably the first op-amp you can't beat using external front end transistors in a mic amp. I have not tested the OPA1612 with high value bias resistors to see if it has the latch-up/bias current correction start-up issues of the LME49720. Its more fun to listen to the music. Dual customzied solution will give unmeasurable distortion (possibly -180db). Opa1656 and opa1612 without tweaking have better performance than almost any discrete solution. hence, once you have a LM4562/LME49720 or a OPA1612 I would not worry, the circuit around is what makes a bigger difference. How to choose between lm4562 vs ne5532.
