that depends on the application... in summing amps 553x is likely superior.living sounds said:In my console I get much lower distortion and noise with NE5532/34 than with TL072/71 even though the circuits were actually designed for the latter. Better grounding and decoupling was added, of course.
But why would somebody do that..? I often used 3 flavors of op amps in console design, high z low gain, low z higher gain/drive, and don't care using $0.12 op amps (like 4560) where it doesn't matter.I guess if you were really carefull with loads and only used it in inverting configurations it could be ok, but it should be difficult to design an entire console with only TL072 and not make compromises wrt performance.
