I heard people mentioning that Koss Porta Pro mod with Tera Player is match made in heaven. :) And I cannot find out what modification on PP to be made. Can anyone help me to find about the mod? Thank you. :)

Yes is correct what you just said,been using mine for around 3 years now.Amazing sounding together.
The modification is : drill 17 holes x 4 mm in each plastic grill that covers the speaker.
Just be careful not to touch the membrane.

Thank you. :) Is there any photo where to put holes in Head-Fi thread? I tried to search for it but only found many mod on pads but no holes.
