You also get a choice of op amps: a 4558 as in the original, and my fave for almost any op amp circuit, the OPA2134. You could try swapping the OPA2134 with a NE5532 initially. Tried all three in a TS at one point or another. 5532 are BJT and tl072,opa2134 are JFET input. Let me preface this post say a couple of things. 70) I have used LM6171 (single version) - and found them to be the best for me - and also the cheapest of the better ones by a large margin. I have selected the NE5532, but OPA2134, TL072, or TL062 would all work as well. Because the LM4562 has considerably more available gain (loop-gain) in the audio-spectrum compared to the NE5532 and LM833N, this translates into lower THD. The OPA2604 is a 8-pin DIL dual-in-line device with dual internal op-amps. Flavors of Audio Op-Amps I was looking for audio Op-Amp that suit my ears, so I decided to test a few well known audio Op-Amps from Burr-Brown (OPAs) and Analog Devices (ADs).

The NE5532 is cheap as errr chips, so it might be worth getting a few to experiment. Not that the opa have much higher input impedence than the bipolar ne5532. The audio DACs are 24bit, 192kps WM8740s from Wolfson, used in conjunction with Burr Brown OPA2134 and Texas Instruments NE5532 operational amplifiers for the analogue, semi-balanced, DC-servo controlled, buffering and filtration circuits. "The NE5532 outperforms the OP275" is a quote I read in a different thread as a response to one of my posts. I've also done this particular swap on several Soundcraft consoles (160+ at a time)and power supplies will need to be re-thought if you go whole hog like this. But do they? The chip companies don’t help the perception implying some of their op amps offer better sound. The OPA2134 is similar, but better since it has a far higher slew rate and is legendary in its tolerance to poor design. Die nackte Wahrheit über Operationsverstärker Unter Audiophilen gibt es ein allgemeines Missverständnis über Operationsverstärker: sie sind einer diskreten Schaltung vergleichbar oder gar überlegen. The 2134's also draw nearly half the current as well (4mA vs 9mA), so it's actually kind of a winthat is if you have headphones that are power hungry. 5See test circuit and frequency response curve for 0.
