Lm4562 vs opa2604 specs
Lm4562 vs opa2604 specs. One can almost not find two more different sounding IC:s. The first one is sounding warm and innofensive, and the LM 4562 is cleaner and leaner. I note that the LM833 and LM4562 datasheets contain identical RIAA phono circuits in their application notes. 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. . There are clearly sounddifferences between opa2604 and lm4562. An op amp is part of a larger circuit and is chosen because its specs match those required for the circuit. Switching op amps is likely to cause as much harm as good. An OPA1612 has slightly better specs than an LM4562---less noise and distortion, faster, and more output voltage swing. The LM4562 is miles ahead of the OPA2604 in terms of sound quality, if bypassed properly with an MKT cap. You could always try the LM4562 (or the single version LME49710). Both are musically better than ne5532, in my subjective opinion. 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. An op amp is part of a larger circuit and is chosen because its specs match those required for the circuit. I've been researching and designing possible solutions around LM833 op-amps. The LM4562 datasheet indicates it has at least 12dB greater open loop gain than LM833 at all audio frequencies. The opa2604 is a fet opamp and 4562 is a bipolar based IC. The sound quality comes from the entire circuit, not the op amp. hye whlaf ulaiarow vichf loritt rtxth kgnus xdk msjzg gwrtu
