Za audio primene daleko je bolje rešenje sa LME49710 po istoj šemi, jer se tada dobija 10 puta bolji THD uz 10 puta niži šum. Primer za takvo rešenje je drugi stepen u preampu LA Vol. 5.

The INA137 and INA2137 are differential line receivers
consisting of high performance op amps with on-chip
precision resistors. They are fully specified for high
performance audio applications and have excellent ac
specifications, including low distortion (0.0005% at
1kHz) and high slew rate (14V/µs), assuring good
dynamic response.
