HD650 has nearly as much bass quantity as the HE-400?  Aw haaaaaaalllll naw!

But then, let's not start the whole presence and impact nonsense. All I'm trying to say here is that the K702 Annie has plenty of bass. Noticeably more than the Q/K of old.
For others: (again quantity, doesn't matter if it's sub or mid bass)
XB500: 10 (only bass)
Ultrasone Pro 900: 9.5
D7000: 9.5 (presence being mainly sub bass compared to the Pro 900's mid bass)
DT990: 9

+1 

having owned hd 650s + these headphones at one time or another, i agree 100% with this bass quantity comparison. 

btw how does sub-bass quality and bass decay compare on k702 annie vs. hd 650? the hd 650s have very clean deep sub-bass that is very subwoofer-like imo without becoming bloated or exaggerated, though it tends to be on the one-note side at times.

You guys must have had amps at the time that really brought out their mid-bass impact.  HD650 has no sub-bass either-- not subwoofer like at all.

the hd 650 has very good sub-bass it just isn't as strong as with other headphones like the denons or beyers. it was still quite enjoyable though and did come out more depending on the song.  

i do agree though that the hd 650s was slightly lacking in the mid-bass, it wasn't bad though.

Please define "sub-bass".

i define it as frequencies under 50 hz, or even 60, but i think of 60 really as the beginning of bass

I think if that is how you define it, then most mid-fi cans have sub-bass.  Of course this is all relative to 1kz.  You could show 40Hz on name that headphone but 40 to 60db down?

I define sub-bass as at least 40Hz and below and not that far down relative to 1kz.  This would include orchestral bass drum, pipe organ, contra bassoon and tuba.  The planars can do it, the expensive Stax can do it, some of the older Denons (5000,7000) can.  IMHO.

Queue me, the HD650 defender (after I was just attacking it!)  To me HD800 is more of a sidegrade on sound signature alone.

the hd 800 sounds nothing like the hd 650, its much more neutral and open sounding. way diffferent sound.

the lcd-2 sounds closer to the hd 650, quite a similar sound signature, except the lcd-2 is dark and linear whereas the hd 650 is dark and smooth

both headphones are on a completely different level from the HD 650s. both are huge upgrades IMO

A natural progression implies that it needs to sound pretty similar to what you're upgrading from.  Otherwise it's not so natural.  This is a hobby where sound signature alone can mean the difference between very enjoyable or completely unlistenable.  Queue the LCD-2 vs HD800 debates, the Sennheiser vs Grado debates etc-- and of course, the HD650 vs 800 debates.
