Difference between NE5532P and NE5532AN

[klitgt]

Hi out there

Do any of you know what the difference is between NE5532x opamps?
They may come from Signetics. Texas instruments or Philips.

I want to know how NE5532P is different from NE5532AN

I have been told that a provider called JRC has launched a 5532 without NE prefix that is compatible with NE5532X types.

What is the features of the JRC product as compared with the "originals".
I have understood that the JRC performs better in audio = HIFI equipment.

The NE5532N is the standard version and the AN is a specially low noise premium version.
The NE5532P are not in the Philips /Signetics data sheet..

I have made a "null test" between a NE5532N from Signetics and a JRC 5532 and the NE win hands down.

Paul McGowan, of PS Audio fame (he even shows up sometimes), claims that only the Signetics version is worth anything.

For me , the only version that is close to the Signetics , is the TI version.

The P version is a TI product. I have seen it myself.
It is in a circuit (2U-1435 "module", see diagram of details in a Denon cd machine DAC board. Input to NE5532 comes directly from IV converter. IC106 pin 7 goes directly to the out RCA socket. IC106 is btw also NE5532P).

I am trying to find out (also in another string) whether there might be an improvement to get by replacing the NE5532Ps in the 2U-1435 circuits and the IC106 (and IC146 for the other ch) by AD825 based opamp modules.

I can tell that replacing the IC106 (and corresponding for the other channel) by AD825 based opamp modules gives a better, more fine grained sound.

Apparently the NE5532 in the 2U-1435 circuits serve another purpose than the IC106 and I wonder whether they should be different from the opamps in the IC106 position.
I know that they could be single versions of any corresponding opamp, but that would require changing of the pin positions. It is easier just to replace by another double opamp.

I am new to DIY Mods to cd players. I want to upgrade all of my collection of Denon cd players:

DCD-1420
DCD-1500II
DCD-1520
DCD-1560
DCD-2560
DCD-1700
DCD-3300
DCD-3520

and a few Nakamichi CD-4 players.

So for starts, which opamp should I start with?
OP275, OPA627, or others?

Maybe the moderators should split this thread into a new one?

Hi Klitgt

I have been studying one Denon 2U-1435 module and it seems to me it´s purpose is a unity gain low pass filter. Am I correct ?

The little sub board marked 2U-1435 in post #6 is just a buffer... the LPF is the LC network below driven via a constant 6K8 source impedance (R702/752).

This is a very old thread, klitgt hasn't been on here for nearly 12 months
