19 maj 2017 · By most standards the LM4562 is a superior op-amp to the NE5532. I'm still (perhaps irrationally) fond of the OPA604, maybe because some equipment I really like used it. That's a FET input op-amp though.
10 paź 2020 · For me its clear evidence that LM4562 is a very good op amp. I have also tried opa1642, 1612 and 2134, but they are all slightly inferior to lm4562 soundwise in Aiyima a04.
21 mar 2019 · The A-138o, which is the output module for the A-138p only has 1 quad TL074 opamp. I thought I would try and do something better with it, seeing I have 8 channels of audio going through it. I purchased a Brown Dog opamp adapter and swapped out the TL074 for two dual LME49720 (LM4562) opamps.
25 lis 2015 · So far I read the OPA2134 as an upgrade to the LM but its quite expensive, has anyone experience with this op amp or do you know any op amps that you consider an upgrade from the LM4562?
17 mar 2009 · I just found out that you can get LM4562 Op Amps for free from National Semiconductor. This is pretty cool, and I've always wanted to get into DIY audio...
29 cze 2004 · high-end opamps would work great for filters and such, but not for audio purposes. the LM4562 and OPA and AD8066 and AD8620 are considered good opamps but they sound extremely muddy and smeared and undynamic.
7 sty 2021 · So considering NE5532, LM4562 and OPA2134, OPA2134 gives best measured results in AIYIMA A07. 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. We get lower current noise and better EMI resistence.
