At most you may say that all of my preferences are directly related to my particular music tastes. Then again, audio is subjective in nature, so what did you expect
No problem at all, I just wanted to highlight that this is YOUR personal preference, in YOUR application circuit, with YOUR music, in YOUR system, for reasons YOU only know.

A newcomer here could by mistake take these personal opinions as somehow having any value for other people with other music, other systems, other topologies.

I do think that all my experience and my neverending tests could be of some use for others.

But as I myself wouldn't take anything read on a forum as gospel, so I would expect others to do with me

Surely there all interchangeable! Nothing like a 1000V/us device with no ground plane and poor supply decoupling.

As far as me, I've compared the LME49710 (NA and HA) and LT1028 extensively, and the LT1028 is what I'd take anyday. Be sure to try the ACN8 if you choose the DIP package.

I'm listening to the Jayhawks' Rainy Day Music, a very familiar record which I had forgotten for a while... yess, the LT1028 proves again its transparency. No special effects to be found here..

It was just an example of applications where one OpAmp can be better than other (I/V versus preamplifier).
NJM2068 has 0.001% TDH at gain 20dB, 0.56uV noise, 6V/uS SR, 5.5MHz GBW.
OPA2134 has 0.000008% TDH at gain 1 (would be some 0.0008% at 20db), 1.2uV noise, 20V/uS SR, 8MHz GBW.
In a pure analog stage, 2068 is slightly better, but on an I/V stage 2134 is better. You are testing the OpAmps in preamplifier...

J'ai tout compris




I'm thinking that I wouldn't mind trying the AD8599, although I already know from reliable sources that it's not as transparent as the LT1028.

I've replaced the LT1028 with the LT1363 and I seem to prefer the latter

It has a more mellow and warm sound. Love it. I'll make a quick comparison between LT1363 and LME49720HA to decide what to stay with, at least until I try the OPA1611 for which I have high expectations.
