Well for once on headfi, I actually got what I wanted from user replies!
Anyhow, I already have your wooden african padouk pads to fill the magnum drivers in. In which Turbulent Labs has their own set of Vimeo videos to guide me through the whole way. https://vimeo.com/51110396
Thank you for your response, I'll definitely take the extra caution for installing these drivers now.
The look of these headphones are quite embarrassing when they're on my head actually. However I have a set of HE-400 earpads and I hope to glue a set of grado earpads to make them an over-ear headphone. Then I have another set to make them an on-ear portable headphone.
I'm actually hoping the headphone I'll assemble will sound better than my AKG Q701's. If they do, well then I will actually sell off half of my headphone inventory.
hmm a he-400 pads? which? the pleather or the velour one?
I liked my magnums best with L-Cush pads on them.
