I'm not aware of any other headphones that use the Lemo connector.
The connectors are $20-$30 each. A 4-pin balanced connector is $4. Decent cable (mogami quad) is less than $1 per foot. Fancier cable is maybe $1-$3/foot (times at lest 4). A decent cable should cost that much to make. I made a 16 strand copper cable for under $100 and about 6 hours of labor.
Thanks!
I am certainly not capable of re cabling myself, or building them from scratch.
So, if somebody can suggest where where to get Utopia cables from, would be great.
There is always that eBay seller that does all kind of cables, including the Utopia cables for $200 + shipping.
On another note, does anybody here uses Utopia with Mjolnir 2?
