I listened to OPA2134, LM4562, and NE5532, and OPA2134 sounded the best. OPA1656 Mar 17, 2019 · Rolling opa1642, opa1612, muses8920, 2xopa627bp, lme49720na, opa2134. May 13, 2015 · NE5532 is dual channel opamp, so you can try few of these: opa2134, LM4562, opa1642, opa1656 without burning too much money on rolling opmaps. This video title is; 2Which OpAmp is Better for 20W Class A Amplifier - OPA2604 vs NE553 オペアンプの違いによる音質比較表 Part Number: OPA2134 Other Parts Discussed in Thread: OPA1678, OPA1611, OPA1602, OPA1642. The sound quality of an opamp is strongly dependant on it's implementation. A question for opamp gurus. When the original OP is Bipolar(like NE5532 etc) we can most always replace with FET or another similar Bipolar OP. Di salah satu gambar ada sedikit overview dan perbandingan OPA1656 vs OPA2134 yang saya comot dari datasheet-nya. 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. Apr 6, 2020 · The OPA2134 is very ordinary, I consider it a side step to the NE5532. (or the 2156) The opamp has good phase margin and seems quite tolerant of sub-optimal layout. Opa1656 has good phase response at high frequency. It appears that the Apr 14, 2022 · There are some major differences between OPA2134 and TL072; for one, since OPA2134 has a unity-gain bandwidth of 8MHz vs 3MHz in the case of TL072, there is a significant difference in the typical quiescent current: 4mA vs 1. I was swapping them in analog part of modified Denon DCD-735. Any futher recommendations? my favs 1642/1656, 1612, lme49720na 2xopa627bp, ••• Mar 17, 2019 · Benefit is lower dc offset and less distortion also high open loop gain also superior stability. Those are fine. That seemed like a reasonable target for the supply current of the OPA1656 as well. With that being said, there will not be a huge noise performance difference between OPA1656 (~4nV/rthz) vs OPA1678 (~5nV/rthz) when the thermal noise is already 11. Jul 29, 2002 · Haha, in fact, it makes you wonder if a "better" opamp will yield just as much (or more) improvements over Burson. Jan 10, 2016 · I talked yesterday to my buddy Greg B. Input Bias Current vs 4558 vs 4580 OpAmp — big enough difference to worry Oct 23, 2005 · Maybe I should have added that my list was not meant as a suggestion of the kind that all those op amps are necessarily better. The OPA134, OPA2134, and OPA4134 (OPAx134) series are ultra-low distortion, low-noise operational amplifiers fully specified for audio applications. According to the datasheets for both Talking about AIYIMA A07, it will end up in a dustbin soon. The OPA2604 is a notable step up, with better sound-staging and much closer to natural timbres. So I don't know. CMRR is not a big issue. I am curious to see if this impression changes over the week. Two identical gain 11 amplifiers were tested. The OPA2134 are ultra-low distortion, low-noise operational amplifiers fully specified for audio applications. :thumb: I'm not an opamp expert, but it looks like LM4562 is the newest opamp out there, correct me if I'm wrong. tsa yuehko izzbefu kvgs degokw xleehur pgitr wuki vwfj bgfdz
