Fang has said direct 50w is safe but when I asked him about my 70w receiver, he said the HE6 could handle that without the adapter. 

No adapter required then. Those resistors just colors the sound.

A local hifi store's selling the AR D70 for $1,099.

If the filter caps have been replaced, all tubes are fairly new, no scratches on the faceplate, output tubes have been biased, and no hum, and its a Mk. II then that's a very good price.

Figured it was, don't know the details though, I was more eyeing the used Gallo Ref 3.1s at $1,200.

At the Seattle meet yesterday one of the listener's turned the volume past 1 o'clock on my amp and the HE-6 survived!

I might be stupid but the HE6 does not distort like dynamic driver at the end of their excursion telling you to back off.  I kept turning the knob and the sound was clean all the way to the stop.

Clean and transparent enough to blow your eardrums off!

It didn't mine but it was loud, very loud.

Not surprising, the HE-6 scales incredible well with a speaker amp (Rega Brio-R). But one question related to all this:

I've seen that speaker amps sometimes (even though seldom) get some sort of internal short circuit and that it can generate sudden high volume pops / clicks and blow those speaker elements.

What if such an unwanted event should occur while we had the HE-6 on our heads.

- Would we all go instant deaf?

- How do you assess the risk in these matters?

- Would it be prudent to use e.g. In-Line Attenuators (http://www.rothwellaudioproducts.co.uk/html/hi-fi.html)

I have a speaker/output relay in my Marantz so I would think it would shut the output to the speakers before any damage can be done to the He-6/ears.

Attenuators won't provide any protection , all they do is act as passive volume control by reducing the output (gain to less than 1). You can get the same protection by turning down your volume.

I would think the in-line attenuators would act as some sort of protection since they decrease the gain received by the amplifier from the DAC. I.e. if some sort of hick-up should occur in the signal path before the amp the ear pop would be reduced somewhat.

The reason I ask is simply that I blew two Heil Tweeters in a pair of Audiovector M3 Avantgarde some years back. For some strange, unknown reason, the computer or the Primare amp generated a pop (LOUD) that made both tweeters to "melt down". It was not a pleasent experience, and I still remember it. Would hate if that happened while wearing the HE-6 on my head...

Only if put them after the amplifier stage but then it might affect how the HE-6 sounds due to voltage drop.

Hi, last night I took my (not so much used) HE-6 off my head.  Kaboom! The left hanger cover (or whatever the correct name for it is) catapulted and hit the HD800 box a bit away! HE-6 is now broken into two pieces, see pic.

Note that the strain of the headband is handled by plastic screwed into… plastic! After I get the headband replaced I don’t know if I ever dare to put the HE-6 on my big fat head again.

That's unfortunate, hopefully its covered by warranty.

sad for a product in this price range. for how long do you have'em? does this happened to other models too (aiming for he-500 in near future). if you're out of warranty, maybe you can set a tiny bit of power glue to each screw and screw-holes to fix it. but u have to be careful, because if glue reaches the sliding metal piece you won't be able to set size anymore. or if you're able to take off the top of the covering you can drill the screws on/in a different spot through to the counterpart of the covering.
