*Edit- Fang just called me back as I was typing this (I called him yesterday), and he told me that the impedance box and speaker cables will be ready in one month and the price will be +/-$100 give or take a Heineken.
In the meantime, the prodo HE-6 can be run directly out of any headphone amp that has a decent output. No portables, but certainly any amp that has minimal cujones (sp?).

 
We recommend headphone amp which can provide 1.5 to 2w per channel at 32 ohm.

I'm not clear on how the addition of a resistor would eliminate hum.  Even  mismatched impedances will not CAUSE hum, it can only be generated in the power supply rectifier circuitry as unfiltered ripple or be the result an external ground loop. 
 
I drive all of my balanced headphones directly from the speaker terminals of my Virtue 2.2 and have zero hum, nor did I have any hum when driving them from the speaker terminals of my Signature 30.2.  


wow.... that would be bad if the problem is an external ground loop, I already sent back the LCD-2's.

Thanks for the spell check. Is that the left one, the right one, or both

I used my Dared 300B quasi mono blocks which put out 13 wpc with no hum, and some seriously excellent sound, in all of the registers.
I also used them in every headphone amp that I own (non-portable, and the only one that wasn't a good fit was the Valhalla.
 
The Valhalla is a real nice amp, especially for the money, but i felt it's not a good match for the needs of the ortho, including the lCD-2's.
 

thanks immtbiker, I doubt if I'll have the patients to wait for the Head-Direct speaker cable... I'll have to get one made

As i can understand i can use HE-6 without impedance-box if the amp is weaker than 70w! Here and there i can read that you should buy and if you can use a nice ordinary amp and connect them to the speaker taps. If i´m not have any amp today maybe i should look for something that works without the impedance-box. So, maybe this little tube amp can be something to connect straight into HE-6.
Maybe someone here that had the oportunity to listen to it before or can try with HE-6 and can comment the sound. Good review here with ordinary speakers and the price tag is very nice! http://www.6moons.com/audioreviews/yarland/yarland.html

I have had excellent success driving my HE-5LE's and my K340s directly from the speaker terminals of my 40wpc Virtue One and Virtue 2.2 amplifiers.  They deliver superb performance at a very reasonable price point.   (virtueaudio.com)

Couldn't it depend on the grounding scheme of the headphone, whether or not it will hum when driven from speaker terminals?


I guess I can find out through a process of elimination - if the HE6's don't hum, it may have something to do with the LCD2 - if the HE6's hum, it may have something to do with the Leben.

Great! The Leben puts out 15w at 4/6/8 ohms (switch selectable).
 
Have you tried the HE-6 driven directly from speaker taps?  Is there a hum?
 
I drove the LCD-2's directly from Leben speaker taps. The good, I thought it sounded better and the volume headroom was greatly increased - the bad, there was an audible hum.  The hum wasn't terrible, but bad enough. When I ask Yoshi (Leben) about it he replied, "A resistor is applied between the output transformer and the headphone [size=medium]output to cope with headphone application, therefore, if you use a headphone directly from speaker output, there should be noise or hum. (It will not damage the amp, but is not a proper application)."[/size]
I don't understand how all this works, but I assume the resistor is needed because of the impedance mismatch - speaker output 8 ohms and headphone load 50 ohms - but that's just my uneducated guess.

I ran the production HE6 out of a Marantz 2220 vintage receiver rated at 20wpc and a Red Wine Audio Signature 30.2 LFP-V Edition and I did not hear any hum. Cheers!

Print a copy of the invoice from the head direct site?

Anyone have a shipping notice yet? If this isn't a pre-order I'm not sure why they aren't shipped out yet.

I believe after receiving the request for phone number, they are on their way very shortly thereafter.
