Finally finished the Uber version of the HD25-1 mk ii. I have been working on them for a few months and they are just about there now.
These ones have 24ct gold gilding on them just for kicks. As you can see from the pick they are fitted with an audiophile grade cable.
Here are some of the mods that have been done. ( DO NOT TRY THIS AT HOME UNLESS YOU HARE HIGHLY SKILLED AND HAVE A DELICATE TOUCH ) We can perform any of these mods for you for a sensible price
I have 24ct gold plated the springs in the sockets and gold plated some Cardas HPSC connectors to match – These have then been fitted to one of the hand braided audiophile cables and matched up with a neutrik jack
Mass loaded driver enclosure. I have added a little extra mass to the driver enclosure using lead strips and added some bituminous vibration damping material round that. This ensures more of the energy from the diaphragm goes into producing sound rather than vibrating the casing
On the back of the driver there is a similar arrangement and the bass ports are partially covered. The mass loading gives you more accurate bass but also more bass in general so the bass ports have been reduced to lessen the bass wilst keeping the extra detail
The pads have been washed to make them softer and the foam disc has been removed ( i like the extra bit if treble you get )
Inside the cup I have replaced the standard damping material which is a felt disc with more high end damping material – this helps them block out even more noise and makes the headphones sound more open – they sound less boomy and more like open back headphones.
