Mine has a screw on 1/4 adapter

Another way to differentiate between the two cables:
 
The HD600 connectors that go into the earcups are red and black, whereas the HD650's are both black.

My HD 600 which was delivered from RazorDog last week looks like this.

 
Yeah, that is the classic cable. No switch there.

Doh!  I found that after emailing razordog.  Another Sennheiser POS.......can't be used with any other 3.5mm plug!

Yap, I found out this yesterday using my IEM.   I heard the sound only from the left channel when 3.5mm plug was connected to Senn 6.5mm adaptor.

Interesting... I'm sure my plug is the same way. I think I tried pulling on it, and it didn't budge, so I assumed that it was a standard 1/4'.  It must just screw on/off.  D'oh!!

Recently picked up a wireworld starlight 6 digital coax cable to link between an M2tech Hiface 2 and Nuforce HDP.  The difference between the old monster cable I was using and the wireworld cable are staggering through the 600.  My setup is hiface2 > HDP > Bottlehead Crack.  The new interconnect seemed to really smoothen out and extend the treble while clearing up the muddy mid bass I perviously surmised was the tubes but I now suspect to have been jitter.
 
Does anyone else have similar cases or finds?

@Jmstrmbn
I haven't been able to experiment with different interconnects but I just ordered a Bottlehead Crack for my HD600.  I'll definitely post my impressions once I receive/assemble the amp.  How are you enjoying the combo (HD600 + Crack)?  
 
I am currently using a 1st generation X-Cans Amp with my HD600 so I'm hoping for a nice improvement.

Yes, actually I do. Last night I tried my $35 Cardas HP1 interconnect for my HD-600 and 650 and it made a noticeable improvement.
Someday I might get a Cardas cable for my HD-650/600. $200 is kind of a bit overkill for me for such a small improvement though. I wish Cardas wire was easier to find in bulk, but only one company in canada seems to carry it. I heard it's hard to work with though.
 
Best thing about this Cardas cable is the build quality and how tangle free it is. It retails for $50 and I would have paid that.
I don't mind paying a little extra for better built cable that's (possibly) made in the USA.

The following is all IMO:
 
The only other amp I have used the 600s with is the Nuforce HDP. Hands-down the crack is far and above the HDP.  It has a wider soundstage, extends lower in the bottom octaves, and has a more natural timbre.  The Crack seems to layer better as well while the HDP had a relatively flat staging.  This is not to say the HDP is bad, without hearing the Crack I was happy with the HDP but going back and forth between them is a night and day difference in favor of the crack.  I am using the stock crack by the way.  No upgraded caps, tubes, etc.  Another benefit of the Crack is I find that I can really enjoy the music.
 
The full chain is:
 
Audirvana + (Direct + Integer)  >  M2Tech Hiface 2  >  Nuforce HDP (DAC)  >  Bottlehead Crack   >  HD600s
 
Aside from the Wireworld Starlight 6 between the Hiface and HDP all other cables are run-of-the-mill stuff.
I won't get into cables as that's not the point of this thread but I found a HUGE difference between the starlight and the old Monster cable I had been using.  If anyone is interested PM and I will describe the differences/Improvements.

Just ordered a pair of these and an amp for my iMac, going from a $50 pair of Skullcandy in ears to the 600s, so...can't wait.

You'll prob pass out from the sound quality difference

After reading this thread, I couldn't resist.  As if I need another set, but found a good price from a distributor in HK, and they've just arrived.  Out of the box, they sound phenomenal, already.  Am running them through a Fostex HP-A7 while burning them in and listening periodically alongside the HD700, and with classical especially the sound is indescribable, actually brings tears to my eyes.
