How noticeable these differences are and whether the differences are good or bad depends on your specific application (RIAA equalizer, line driver, tone control, post DAC filter, etc. , at only ~ 60¢ each, AND stlll available in PDIP-8 format. I once convinced a famous designer to throw the NE5532 & TL072's out of his CD-players analogue stage (in favour of LM6182/LM6172) and test with the AP2 multitone test. Although I am a fan of the OPA2134, I still have very considerable respect for the NE5532. If the orginal OP is a FET (like TL072, OPA2134 etc) we may be careful sometimes NOT possible to replace with Bipolar (like NE5532 etc). And it is a JFET opamp, which is always preferred by I'm looking for a replacement for the NE5532 (dual opamp), which can handle +/-18Volt and doesn't oscillate relatively easily. Taking advantage of a wide power supply range and mounted on a DIP8 bracket, it Compare NE5532N by undefined vs NE5532P by undefined. The NE5532’s high slew rate — the speed at which the output voltage can change in response to a change in input — makes it a sensation in audio I am using interfaces that come with NJM2068, NE5532 and TL074 stock. I upgraded the volume pot and built an external large transformer power supply (in lieu of a "tap" from the original power amp;s transformer). The bass was less muddy and overbearing while the midrange and treble clarity improved greatly. No. I looked at the Slew Rate In this hobby, we come across a lot of different tweaks and tricks that claim they improve the sound quality of the component you're upgrading. But more importantly, it's CMOS. Dynamics felt better, bass felt more defined and the upper midrange seems to have more air. Thread starter invalidbuffa; Start date Aug 2, 2013; 1; 2; Next.
