Back to 650 it is. Is there an easy way to pry off the outer grill? In case dust/debris get thru the grill holes.
A chainsaw would probably work

I will warn you, the HD650s will need more current then you Denons currently use. I'm just hoping you to temper your expectations unless you have an amplifier to do them justice...

Are you kidding?
+1: I could only stand that type of a song for 1-2 seconds at a time... Let the electronica age thrust us forward!

We really should keep the HD 650 headphone thread a headphone thread.
We have some very cool threads on HeadFi for music sharing:
Electronic music exchange - valuable resource for keeping up with the electro scene, and some good oldies too
A Bit of Music and a Bit of Fun - Eclectic variety
That's a brilliant song I haven't heard before. I do like Natalie Merchant though. Have you heard her singing Motherland?

Took the plunge. My 650s will arrive in about 5 days. Looking forward to excellent sound!

Volts RMS required to reach 90dB SPL: 0.205 Vrms
Impedance @ 1kHz: 320 Ohms
Power Needed for 90d BSPL 0.13 mW
Volts RMS required to reach 90dB SPL: 0.082 Vrms
Impedance @ 1kHz: 25 Ohms
Power Needed for 90d BSPL 0.27 mW

already 3 thumbs up when it's utter nonsense. scepticism really isn't your thing guys ^_^.
just knowing that lower impedance(the rest being equal) will let more current flow, should have made you suspicious, it certainly did for me.
if innerfidelity's PDFs contain no mistake, and I didn't multifail typing on windowzzz calculator while eating pringles, then they read:
HD650
the voltage was as mentioned 0.205V, I=P/U=0.00013/0.205=0.0006341A
so the amp provided 0.635mA at 90db into that one hd650. and that's what current is!!!!!!!!!!!!!!!!!!!!!!!
AH-D5000
doing the same with this one, I=0.00024/0.082=0.002927A
the amp had to feed 2.9mA to drive that headphone to 90db (takes less voltage but uses more power, it was obvious current would be bigger here)
that's more than 4 times the current used to drive the hd650 at the same loudness.
ok thanks bye.
For anyone else using a tube amp: Do you sometimes get this weird buzzing sound? I've been having these recently. Not sure if it's the amp, headphones, or DAC. Pretty sure it's either the tubes or the DAC, the DAC is quite old.

i totally don't know how to read this if an amp spec is put in front of me with a hd650
