Audio Op Amps - It's The Loop Gain You Seek, Not The ...
https://sparkoslabs.com/discrete-op-amps/audio-op-amps-gain-seek-bandwidth/
When choosing an audio grade op amp, some opt for high loop gain devices as it is well known that high loop gain makes for a more precise amplifier and lower THD specifications. Others decry the use of high gain devices, claiming the high gain …

Almost any type of op-amp capable of delivering 1-5 mA current can be used for this circuit. Most of any small transistors with maximum collector current handling around 100-200 mA can be used. The resistors R1 and R2 should be selected to supply the biasing point at 0.5Vcc, chose as high as possible but keep below 1/10 of op-amp’s input impedance.
Notes on Audio Op-Amps - Tangentsoft
https://tangentsoft.net/audio/opamps.html
We can eliminate power op-amps, super-high-speed op-amps, high-voltage op-amps, low-frequency op-amps, and low-spec general-purpose op-amps. Audio requires a fairly high slew rate to maintain low distortion, flat frequency response from 20 Hz to 20,000 Hz, and decent output current if the chip is to drive headphones directly.
Audio Designs With Opamps
https://sound-au.com/dwopa.htm
Introduction. There are few audio frequency designs today that do not use operational amplifiers (op-amps, or just 'opamps'). Over the years, the poor opamp has been much maligned, with mainly spurious claims about 'audibility', distortion, and other so-called defects.
Best op-amp for audio use? | Electronics Forums
https://www.electronicspoint.com/forums/threads/best-op-amp-for-audio-use.295668/
I have auditioned many op amps over the years for use in audio. Among the best are the OPA604 and the OP37. More recently I have use NE5534's in my guitar amps. Be careful if using these as they are stable only for gains of greater than 3. Another low distortion, low noise op amp is the LT1028. I have never tried them as they are horrendously expensive.

An operational amplifier can amplify signals having a frequency ranging from 0 Hz to 1 MHz This means that OP-AMP can be used to amplify DC signals (0 Hz) as well as AC input signals (high-frequency signals).

possible to make a suitable amplifier using an op-amp and a couple of external power transistors, but we went with a simpler solution, and chose a chip that was specifically designed as an audio driver, the LM386, shown in Figure 1-5.
