They are headphone mods for K701/HD650/HD800. They are 68nF/63V WIMA polyester types. Gives more detail in the bass on headphones.

Oh right. Well since my headphones are (unfortunately) not even slightly in that league of performance, I'll leave the remaining 2 alone.Originally Posted by StanleyB
Edit:
Oh wait, hang on. I assume the 2 WIMA ones your referring to are the red ones just right of the grey caps, yes?
I was talking about the 10 grey caps 4 on the left and 6 on the right. You only mentioned 4 for line out and 4 for headphones.

You only need to worry about the 4 on the left if it is only LINE output you wish to upgrade.

What would be the best capacitors to use for the 47uf 16V?
I just plan to replace the lineout capacitors and want the best I can get, the Blackgate equivalents, since they no longer make them.

The non-polarized Rubycon are quite good. But I have updated the circuit a bit. So best wait for a new picture to appear from me.

Does anyone know why non polarized caps rather than polarized ones would offer upgrade to the opamp circuit? I thought that the non polars are just two caps back to back effectively. Is it more likely that the improvement in sound could be just down to a different cap?
