Keep on listening I mean, how hard can it be to pick a 741 from an LM4562 or an OPA134.

It IS difficult. I have tried something similar a long time ago with AKG headphone. My conclusion was that the source and the system was not good enough for me to be able to find out which one was best.

I think I need a criteria, but there are many possibilities. A calm sound may be relaxing but it is not transparent. Dynamic is another criteria. I have download the MP3s and listened to 7 of them quickly (only the beginning 20% of the files) with a $5 headphone, and I prefer the banana.

I will bring the files home tonight and listen through my speaker. My speaker is quite capable of showing details. High dynamic contrast is possible with my speaker. Cymbals, drums and such. I'm curious because I have no expectation. My only expectation is that they all will sound terrible

It could be very difficult, if you are doing playback thru a couple of 741s.
But finding the original should not be difficult - it should stand out from all the rest.

A 20kHz square wave would be great just to see if there is any difference in stability.
Why wait

Here is the 741 vs one of the others. 20kHz and 6 volts peak to peak output (which is actually a little below the Marantz max output).

Well, you would think so When you see how "poor" the 741 is then surely it must stand out by a country mile

I have not yet listened.

But in the past I received an ABX disc from a certain un-named "famous" ABX advocate. Quite correctly he claimed that you could not hear the difference between the DUTs. In this case he had messed with the bit depth, iirc. The reason was essentially in the selection of the source (music) that he had picked. That selection was such that differences would be readily masked.

In an odd way it was a funny experience.

Along these lines I have an instrumental cut by Pierre Bensusan which is eery, no matter what you play it on, it just sounds tremendous. Truly. It's almost impossible to play this back and make it sound bad. So, a great choice for impressing visitors, but a terrible choice for hearing flaws or limitations in my system.

Just a thought.
