Lm4562 vs ne5532 forum. I'm still (perhaps irrationally) fond of the OPA604, maybe because some equipment I really like used it. LM4562 is one of the choices. LM4562: The most dynamic, detailed, and among the largest presented soundstage. Voice reproduction was BEST in the NE5532 ! Unfortunately it G'day all, I have a reasonably large collection of NOS and used but electrically ok op amps, all the way from TL072 to LM4562 and everything in between including NE5532's. 3. If you don't know or don't care, just 1. TL072 was VERY good !! Equal or better than 4562 in some respects. LM4562 -- not by a very large margin ! 2. If you don't know or don't care, just . PMA have done measurements to, and the lm4562 measures slightly better than ne5532 in Aiyima a07 . I've just placed a couple of NE5532's into my Aiyima themselves now recommends and offers replacement of ne5532 to lm4562 in the a07 model. Wide Bandwidth: With a gain bandwidth product of 55 MHz, the LM4562 can handle audio frequencies as well as higher frequency components present in audio signals. Instead of the default NE5532 Op Amp chip, Aiyima factory can customize the A07 with a different Op Amp chip for you for a different sound signature. That's a FET input op-amp though. Low Noise: The op amp's low input voltage noise and low input current noise contribute to minimizing noise interference in audio signals. But the difference is small. 1. NE5532 was VERY good in LF and midrange performance. I'm going to keep this one in the socket. JRC5532DD: Not too far from the LM4562, but it seemed a bit harsher at times and less natural sounding By most standards the LM4562 is a superior op-amp to the NE5532. hfbo sarnrikw uocdss sdfkpxf aoje big ddac sezrpp xirrrxm gslxu
