Let me share with you the tone and working voltage of the OP

The Op-Amp of the AD series has a brighter sound in the high-frequency range, quick response, and surging momentum.

The Op-Amp of the OPA series has a warm tone, all frequency bands are even, especially string music is even better.

49720HA: Less music, less warmth, low noise, and affordable price. I definitely want to buy two

128SM: Bright mid-range, good extensibility of treble, slightly less bass, insufficient sense of space, but the warmer sense of music. The vocals are first-class, but the shortcomings are low noise and big noise

627SM: The mid-frequency is not as bright as 128sm, but it is still good. The high and low frequencies are fast and accurate. The sense of space is strong. Low noise is low. It is suitable for listening to rock, pop, and metal, but the shortcomings lack emotion in a human voice.
I have heard of 627SM, 128SM is tight, and both of them are top OPA, but my comments are different.

The sound of the 627SM is very delicate, the sound is faster, and the low-frequency quality is better.

128SM sound is more delicate, clear sound is slower, warmer, high, medium, low, very balanced, (I think the sound of the recent tube amplifier)[/li]

The sound of LME49720HA is cold, light, crisp, and fast. The musical sense is first-rate but the vocal feelings are not good.

NE5532 has many different sounds. The modern and cheap NE5532 pottery seals have different sounds from the ancient Philip NE5532 pottery seals (Philip’s is thicker, but the explanation is not strong). NE5532 is just a name, and every factory produces it. The sound is slightly different.

Another wild and cheap Op-Amp is JRC4580, which is also a wild Op-Amp that won't be wailing but not too loud.

AD8599/AD8610, etc. are relatively unmodified, straight-out, and straight-in. As a result, there are very few requirements for wiring and accessories, but they are definitely better than BB when done well. I think that if you change the capacitors (and you need to know the tuning by the teacher), you can try AD products, otherwise, the performance of these AD's high-priced Op-Amps will not be brightened by changing the OPAMP alone.

What about the taste, though?

I think AD series has more of an epoxy-like taste, whereas OPA series tastes more like ABS.  The leads on both gives a nice zesty metallic zing, although I warmly recommend avoiding tasting used opamps, as many fluxes leave a toluene-like chemical aftertaste that may be difficult to forget.

I haven't yet made a true pro tongue-board for licking opamps in combination to get true gastronomic explosions of combined tastes, but that's my next project.

For true connoisseurs, the opamps should be powered when tasted, although for hobbyists, it can be difficult to appreciate the nuances then.
