I received a few emails about the type of wire we use in the RWAK100 mod. It's Cardas Golden Section Litz wire (copper). It's my favorite
wire in these type of applications because its solid copper, enameled (so there is no dielectric of a standard jacket), and very pure (99.99+). I've used it to
make custom short interconnects (under 3 feet) and compared it to a lot of different types of wire. It offers a balanced sound, with no stridency in the top-end,
and is very transparent. Way better than going through the circuit board traces and the connector that attaches the MB to the headphone board.

Having said this, we only use about an inch of wire per channel. That's right - a very small amount. So even using the most exotic of wire should
not have a any noticeable difference in comparison. What is much more important is:
- The quality of the solder connections
- Making sure the wire touches the output stage FET and headphone jack leg, and then is soldered on (instead of there being a noticeable amount of solder in series with the connections from a bad solder job)
- The routing of the wires inside
- Making sure the stock signal path is removed (so it is not in parallel with the new direct path to the headphone jack).
- Using the correct soldering iron temperature to not thermally strain the parts.
In other words, getting the job done right (the cleanest, most professional way) is the most important thing. The 1 inch of silver vs copper, etc. makes no difference if the soldering is not top-notch.
And I stand behind my modification work for as long as you own your player. And when the time comes and you need help getting a new battery in there, or helping with any other
non-modificaiton-related issue, you know I'll be there to help with that and offer you very prompt service. This is how I've been doing it since 2005 when I developed the 4G iMod and then
the 5g/5.5g iMod (which has been copied, but rarely duplicated in quality from what I've seen in person and from those who needed service and asked me to help).
I am very careful, do my homework, test, repeat, and offer all my customers very good communication and responsiveness. To all my customers - I am very thankful for your support and confidence in my work, and all your feedback from your emails and posts here.
I would highly recommend trying the Kondo silver RCA cables and stripping it
the Kondo cables are made from very fine strands of silver drawn in the Kondo Laboratory, annealed for up to twenty years, treated specifically for skin effects and then coated with multiple layers of proprietary varnish which acts both as a protector of the silver and as a means of rejecting RFI
