I too have been using Audio Hijack Pro with a bunch of plug-ins to tame the 6-8K peak AND pull up the upper mid range slightly. And boost the bass etc. It works remarkably well depending upon which plug-ins are used etc. I...
One way to verify the actual EQ curve is to run either a white noise source or a sweep generator and use a spectrum analyzer on the back end. This yields a fairly decent look at the overall response curve.
And you can...
Here is something to ponder.
If 150mW is enough for ≈120dB and then you add 20dB of bass boost that equates (roughly) to 100dB of unequalized output elsewhere in the audio spectrum. Yeah I know this analogy is a bit...
150mW is not a lot of power. And is that the amount of power available at 600Ω, or is it just the rated power of the amp?
And if you boost the low freqs by say 6dB which uses ≈ 200% more power at those freqs AND crank...
One thing to keep in mind. The HD 800's have a rather high impedance like 300 to 600 Ω.
Most amps make FAR less power as the impedance goes up and with a 600Ω load @ 100Hz, your amp may make very little...
For some there was a seeming 'lack' of bass.
For some there was a seeming 'glaring' mid-upper treble
For some there was a seeming lack of detail.
All of these aspects are improved in one fashion or...
After trying several variations of the anaxilus mod and then the mod that Tyll shows in his InnerFidelity video, I HIGHLY recommend Tyll's version.
It's cheap, easy, provides solutions to some known 'issues' and aids in...
While there are undoubtedly a few headphones more unsuited to traveling, the 800's certainly belong to that group.
I mean risking damaging $1500 headphones (unless you've got $$$$$$$$) looks like an expensive lesson learned...
