Oh yeah, I did see your Unipolar mod - very cool work considering the challenge involved.
Since my HE-500 is slightly modded I doubt anything will ever dethrone it, just a simple grill mod adds at least 30% more air/space to the sound.

I am still getting used to the sound of mine (300 ohm) and I think it's in the same league as HD600, DT880 etc for resolution, but in FLAGSHIP league for timbre and overall sound presentation.
It REALLY is a reference headphone, it just gets out of the way of the recording.
At first I thought it was clearly something great, but quickly I found the sound... 'boring' ... uncoloured... maybe even bland.
But soon I realised this is one of the few headphones where you're not meant to enjoy the headphone, since it's sole purpose is to let you simply enjoy the music.
The upper-midrange and treble has a certain mild 'crispiness' to the sound that just sounds and feels REAL without being fatiguing, ever.
I still prefer my HE-500 overall, especially in the bass department which is the ONLY place the HD540 lacks IMO. It has the texture but not the volume to satisfy a truly 'neutral' presentation; there's just too much roll-off.
HE-500 maintains a pleasing level of slam into the lowest bass notes that give a similar level of impact to real bass notes and instruments.
HD540 might have simply been tuned for the ears of older folks with failing treble sensitivity.
