Amps that can drive the HiFiMan HE-6 planar headphones - Page 40

The HiFiMan adapter is to protect the Amp or to protect the Headphones?

 

Both. Inside the adapter is a pair of 10ohm resistor in parallel and a 25ohm 1/4 watt in series per channel. The total impedance of the resistors with the HE-6's 50ohm is still close to 8ohms. The 25ohm resistor would hopefully protect the HE-6 from over-current.

OK thanks.

 

So If I decide to try it out.  What would I need, 4 short speaker cables with bananas or spades on both sides?

You can use either one. The speaker terminals at the back of the adapter are this kind.

My home brewed cable looks like this.

So you don't use any kind of adaptor (like the HiFiMan) or resistors between the amp and the headphones?  

 

You just use your home made cable?

I've been using this with no issues thus far.  But there's no protection anywhere.

I use 10ohm resistors in parallel but not the 25ohms. In this amp, I soldered the resistors between the speaker terminals inside the amp. The 10ohm resistors provide some protection too since it absorbs most of the power.

Can you post a link to where I can get the 10ohm resistors?

Cool thanks

Tried with and without resistors, couldn't hear a difference, so I left them out.

It's a good thing that you couldn't hear a difference.  That's even more of a reason to leave them on.

What kind of resistors are you using? The 10ohm resistor also adds protection since it absorbs more power than the HE-6.

Nice resistors, even more expensive than the Mundorfs.
