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.
30 sty 2004 · The LME49720 output stage is optimized for supply voltages under +-17 volts. The LME49860 is optimized for +-14.5 to 22 volts. The LM4562 is similar to the LME49720 except it's in a metal case and has better heat dissipation and drives 600 ohms effortlessly.
28 lut 2021 · Curiously enough it seems to sound its best in combination with the OPA2134. In some respects I think of the LM4562 as a somewhat upgraded NE5532. I have used the OPA2134 as the first gain stage in a number of high quality DIY phono stages, with the LM4562 in the second overall gain stage.
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.
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.
20 lut 2009 · In many applications the LM4562 fills the gap between two of my favorite op-amps; the AD797 and the NE5532. All three opamps have outstanding noise performance as well as very low IMD. All of these opamps have low THD at high audio frequencies while most opamps exhibit a rise in THD with frequency.
