I'm looking for a crossfeed schematic for my HD600, I want a more centered image of the sound so less stereo effect.

Looking at the webb I got several schematics:
Headphone xfeed

i have been looking for something like this but i never knew what they were called. i also find headphone listening artificially wide. the sound should be in your head not in your ears/headphones.
thank you for this 🙂

With the impedance curve vs. frequency of the HD600 anything but flat :

You are not going to get a decent response with a passive cross feed network, unless you use a notch to flatten it first at 100Hz.
And then a Zobel to pull down the inductance from 5kHz onwards.
For a collection of different cross feed network, you can refer to the references (2~6) here :

Thanks for the links Patrick very helpfull, I'm still not sure what way to choose for EQ: passive or digital, I like the sound at 100Hz, I can't calculate the zobel because I don't know the voice coil inductance Le.
With the xfeed I'm looking for a more centered sound but the schematics used don't like the sound. What do you think is the best for HD600?
Congrats for you very nice headphone amp🙂

I looked at building a crossfeed add-on board for one of my amp designs a year or two ago. Looking into it through there were several software crossfeed plug-ins for popular audio players that seemed to be highly rated, so I never bothered. At least one of those was for-pay commercial software too, as I recall, and rather pricey.
Software doesn't help much though if the source is a turntable or or non-PC gizmo! 🙂
Dr Meier did that original post on Headwize way back when (the excerpts in your second link in post #2). Since then it looks like he formed Meier audio, a commerical company, if I have the history right. Here is his crossfeed page:

EUVL has a good point. Crossfeed may be best done on the source end of things (that is where I was going to put it) so a low Z output headphone amp can drive the headphones directly.

We shall never use a passive cross over even with a flat impedance like the HE1000.
Compare to burning off 90% of the output power of the headphone amp in the passive filter, an active filter at the input is a much better solution.

Started with this attached schematic.
I'm hearing better the headphones, the sound is more centered allowing to listen now more details before not listened for the stereo image.
I guess the schematic used is for medium crossfeed, time to experiment with more crossfed schematics.
