Introduction: Numerous opinions and preferences exist regarding op amp selection for hi-fi audio circuits.The question we attempt to answer is "Which op amp is the best for audio applications?" We go on Digikey, look up the AD's, LT's, LM's and NE's, and rapidly find our eyes glazing over from specification overload.

Notes on Audio Op-Amps - Tangentsoft

The OPA627 can be accurate to a fault, if your recording has unpleasant detail in it that another op-amp would ignore or deemphasize. If you have flawed recordings, you may prefer the pleasant lie told by the AD843. Bottom Line: This is a serious contender with the Burr-Brown OPA627 for the title of "best op-amp I've ever heard". I view these two chips as rough equals; …

https://electronics.stackexchange.com/questions/8462/which-op-amp-for-audio
Op-amps have a gain-bandwidth product (GBW) which indicates that the bandwidth depends on the amplification; a higher gain (amplification) results in a lower bandwidth. GBW is closely related to slew-rate, and you want to have a much wider bandwidth than the 20Hz-20kHz of audio to get high slew-rate values. I've found a few interesting parts at ...

With a 30V supply and a single-ended amplifier circuit the power into 4 ohms is only 13.8W. Maybe your speakers are rated at 60W peak which is 30W RMS. An OPA134 single, OPA2134 dual or OPA4134 quad opamp is excellent. The max allowed supply is …

Best sounding op-amp - High-End Audio Discussion Forum
https://forum.audiogon.com/discussions/best-sounding-op-amp
If op amps influence sound as much as people are saying, then op amps are being used in circuits where they don't belong. The headphone amp cited by Chillysalsa is probably a prime example. Op amps, even "good" ones are a lot cheaper than circuitry implemented with discrete transistors, so I suppose that widespread use is inevitable.

Best op-amp for a DAC output | Headphone Reviews and ...
https://www.head-fi.org/threads/best-op-amp-for-a-dac-output.284081/
If the op-amp is connected straight to the DAC output, you better use a FET input op-amp. I'd begin with the OPA2604 , it's dedicated for the I/V stage and does it very well in my CD player. The OPA627 and OPA637 are almost neutral but they miss one point and that's why I don't like them - they lack PRAT, sound kind of slow, uninvolving, they never make me tap, or bob my …
