Leave it downstairs, I'll save you the hassle and pick it up on Sunday :P

First impression:

 

It's damn heavy!!! And I'm very used to lugging heavy things around.

 

I hear no noise floor with the headphones directly into the taps. It's just so CLEAN! So much more dynamic. And I still need it warm up some more!

If I buy a pair of HE-6, is it safe to say I could power them out of my JDS Labs O2 (613 mW into 33 ohms, 0.54 ohm output impedence)? I could power them from the speaker terminals of my Emotiva UPA-200 (125 W x 2 into 8 ohms), but I think I would probably hear the noise floor and might blow my eardrums with the slightest volume movement. I would be using my iPod Touch 5G as my DAC and preamp (don't judge because it's an iPod, this generation sounds much better than my Dragonfly).

Perhaps I would be better of buying an LCD-2 rev. 2 or Beyerdynamic T1?

The O2? If you insist on using it in this application, it would best be served as a preamp feeding a proper amp.

More iron in the Southland!

Will sunrise find you with your gear?

I wish! Fatigue has taken a toll on my body though. I've had a twitch in my eye all week. Damn those long hours of work! and my inability to get myself to bed on time...

The O2 will not come remotely close to powering the HE-6. Period. 125w per channel into 8ohm should be fine as long as you have good volume control. I had my 6 running off the Merak monoblocks at 200ohm/channel into 8ohm without issues (excellent volume control via the Taurus Pre).

^+1.  I also own the ODAC/O2, won't work at all with the HE-6.  Not sure about using it to control volume either as the quality of the pot is not exactly stellar.  But don't worry about 125 WPC into 8 Ohm, should be about 20 WPC into the HE-6's 50 Ohm, I plug mine into the headphone out of my SX-1980, also delivers >20 W into the 50 Ohm (via the headphone).  Good volume control is the only issue.

Since my iPod has 16 volume steps, that should work out to about 1.25 W at 1 volume step. Should work okay, I don't listen loud so I'll probably move the volume slider manually to give more control. I don't know if using that low of a volume on the preamp will degrade sound quality, but I'm guessing it will unfortunately. My O2 has channel imbalance at the beginning of the pot and I can't line out the internal DAC of the iPod so that won't help either.

I've used the O2, and it does indeed drive it if you read my posts.  It actually was loud and has volume range left over to make it louder.  There has been discussions of variances in the impedance of the HE-6 from 40-60 ohms.  Possibly, there might be variances in the sensitivity also as I felt mine was pretty sensitive.  Just like LCD2, the headphones react better with more wattage as my Beta 22, 2-channel thankfully had enough to drive it to bring out it's potential in providing realism and in your face details.  I notice sound is not as controlled with O2 with the both of the orthos, and when the orthos is under-powered you hear a particular sound I can describe is hollow sound.

 

I say, you must try the O2, and another with lots of juice if you think amp is all about loudness.  It will break your preconceived notions, believe me.  With the HE-6, it will.

Well I believe that amplification quality matters, but having more power than necessary doesn't make sense. More power doesn't make a headphone amp sound any different if you aren't using the power. Maybe point-to-point voltage is better, impedence curves are different, and the ratio of current-to-voltage makes speaker amps sound better than regular headphone amps when using planars? I'm just looking for a scientific answer, simply saying it must be better because it is a speaker amp doesn't explain anything.

I'm not trying to sound angry or anything, I'm seriously questioning why speaker amps would sound better.

Well, lots of people are saying that these are pretty hard to drive, and common sense would tell them, it's hard to drive so why don't I just give it more juice?  And whala! people connecting to speaker amps.  These speaker amps have a headphone jack that limits the wattage, so that you can have more volume range.  I think vintage speaker amps with headphone jack is not a bad option for these as these are pretty flat impedance wise and you just need to provide enough juice.  I don't see it reacting too differently to various amps as long as you feed it the power it needs.  Yes, the SX-1980's total power is overboard as you just need the wattage from the headphone jack, but I'm guessing quality of the driving is better since people are recommending it.  

 

I would definately try vintage amps since they can be had cheaper with more power than headphone amps.

Well, if you care enough to do a little research, look for the speaker amps with headphones thread. Lots of discussion on the topic there.
