If you were trying to measure the transient response for two different pre amplifiers, what's the right way to do that ?
Do freq by time graphs demonstrate much of anything ? I would think them a crude measure at best as transients are inherently fast ?

You can listen obviously, and put transient heavy stuff through, like snare drums If you have a Oscilloscope you could put a square wave into the preamp and look at that.. cheers Wiz |

Stepped (10 dB changes) square wave source is I believe one standard method. Illustrates any reaction to change between the two. Or maybe I'm thinking of compressors; anyway, it would work.

I did not particularly notice any huge lack of transient detail. That said, I don't really get much out of other people's mic pre tests, got to get my hands on 'em. |

Oh ya I hear you! I poster here cus then I was curious ,what is the right way to test for differences?

After years of sweating other's opinions, I finally settled down too. I spent years thinking that I was hearing things "wrong" before I made the realization that maybe I was actually the person hearing "right".. |

Use a 2k hz square wave. That's a standard frequency as used by Jensen and others. If you see a slope reduction on the rising edge that's the transients getting missed.
If 2k looks good then try 10k hz. Only a few will pass that unaffected.
