I'm not to worried about it - most of the variances were well under 0.5 dB, and the stuff at the extremes is beyond my hearing anyway

Gents,
maybe someone can help me figure something out. I've been running some tests with copper vs silver cables, and I have found a consistant and repeatable difference in the Group Delay within the 45-51Hz region
Pink is silver, black is copper
what is this group delay and how would it affect the audio? the fact that it is only (afaict) in the low bass region, seems to contradict the usual "silver is brighter" idea
Not the answer your looking for, but I would say that this is an indication that nature is far more complex than we can replicate or measure with our technology.

All these charts are going way over my head
I have my X5, my E12 and my AKG K550s that sound good and that's all I need to know
why is it such a low resolution?...
Hmmmm, good question!
Maybe they used very low resolution files (mp3 @ 96 kbps) for this test chart...
Oh well, in that case here's a very simplicated chart of X5+E12+AKG K550:
Enjoy
No, you're screwing it up. Here's Theo's initial statement:
If you select the custom EQ or one of the preset EQs and set the sliders to flat (as a starting point), you get a flat curve identical to EQ off, but have to live with a 6 dB volume decrease. The drop-off at the extremes in Theo's example is the result of the outer bands being 31 Hz and 16 kHz instead of say 12 Hz and 36 kHz. This while trying to compensate for the 6 dB volume drop-off by increasing all frequency bands accordingly.
And while I'm at it: Theo, how is the resolution of your graphs? Are they smoothed in any way? They seem to consist of assembled straight lines of the length of one octave, with hinted corners at the joints. That's not what I would expect from a measuring graph.
