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.
30 sty 2004 · Looking to buy some opamps for rolling then stumbled on a thread with people saying that the three are the same thing. Some vendors market the same as well. LM4562 and LME49720 are the exact same part... just different model stamped (stated by an ex-employee)
The LM4562 A07 does work really well if you feed it with a good preamp like the Aiyima T6 Pro which also is flexible when it comes to op amps. I tested a few in both units and the best combination to my ears at least is the opa2604 in the output stage of the T6 Pro and the LM4562 in the A07.
23 lut 2019 · AIYIMA A07 TPA3255 Amplifier Measurements LM4562 option. I received my A07 yesterday, on January 6, 2021, shipped from Italy. Purchased at Amazon.de and as stated on their website, it arrived without a power supply. I am testing the A07 with 2 different power supplies.
30 maj 2023 · The LM4562, known in audio circles as a game-changer, represents a pinnacle of operational amplifier design. In this in-depth exploration, we're going to plug into the heart of this chip, allowing readers to truly understand its brilliance and how it has reshaped the audio landscape.
7 sty 2021 · We have now SINAD = 88dB at 5W/4ohm/1kHz and @24kHz BW. 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.
7 cze 2016 · Latest Rating. Filters. Dawgfish. 1000+ Head-Fier. Dec 27, 2022. Great opamp for those looking to upgrade their Little Dot 1+. Pros: Better bass quantity and quality. More liquid and lush mids. Better definition in treble with no harshness. Increased size of sound stage. More precise imaging. Slight increase in overall resolution. Cons: None.
