Both are excellent "jelly bean" op-amps, meaning good all-round performance at a very low cost. The NJM8065 is a much-improved 741 and is about the cheapest op-amp you can buy, so unless you need even better performance stick with this. For slightly better performance at the cost of higher power consumption, the NJM8080 is a good alternative.

May 25, 2017 · I replaced the op-amp chips in my NV400, that had the Peavey factory tone mod installed but NO op-amp updates. Made no difference at all. On the other hand replacing them in a 1000 or 112 made a significant (plus) difference. _____ GFI Ultra D-10, Quilter Travis Toy 12 Amp, POD X3, MatchBro, Cakewalk Sonar and Studio One Pro V4.6 DAWs, MOTU 4pre

Op-amps ranked by voltage noise density (typical) The great divide is between JFET input op-amps and BJT input op-amps. The JFET op-amps have more voltage noise but less current noise than bipolar input op-amps, the TL072 being particularly noisy. If you want the lowest voltage noise, it has to be a bipolar input.
Jun 13, 2012 · Re: Brief review of Cambridge Audio Azur 840a, Jamo e875, Xonar stx & d2x & some OP a Yes, in 2 channel analog stereo mode the d2x without modification had better detailing in the lower mid and upper mid freq range than the stx on stock OP amps. The stx on Stock op amps have better "absolute" middle freq's and similar lows and highs to the d2x.
Parts arrived from Burson, so no op amps at all on the boards now, all 10 are discrete modules. Based on the previous sets, they will take 50 hrs to run in, but even after 5 hours they are sounding much better than the op amps. I will definitely be using this configuration on the balanced input build.
To add a bit more detail, the tuner is a Technics ST8080, the op amp runs non-inverting with a gain of c. 8 by my calculations (4.5k resistor to ground, 33k feedback resistor). There are some sites suggesting that OPA2134 (as found in the active crossover kits in my second system) is a possible replacement, and its datasheet claims pretty much ...
