Where I find a description or differences between Discrete Op Amp

[opacheco]

Hi I would like to start a discussion about this topic: Vintage Discrete Op Amp differences (topology differences, schematic differences, sonic differences…) like fairchild, api, melcor, neve, avedis, burguen, sonic and others?

I read the op amp beginning with vacuum tubes few week ago but now I would like to have a similar discuss about discrete solid state op amp! Any scientific paper about or comparison schematic set in order to check for differences will be a good start point.

Thanks for anticipated!

Just look up our local DOA hero Samuel Groner - META - Discrete Opamps

He also did some major research on the subject - e.g. as published in the Journal of the Audio Engineering Society, Volume 65, Issue 5, May 2017
