Get Vinnie from RWA to mod AK100 to RWAK100

About the Red Wine Audio AK100 Mod, I got this message from iRiver:
“Dear All,
I think you guys already known about “RWAK100”
Well, here are our mentions for this issue, please refer to it.
If you change AK100’s output impedance into 0 ohm (by taking off resistance)
PROS :
1. Sound become powerful.
2. enrich sound of high impedance
3. better balance for Armature unit drive earphone.
CONS :
1. Each headset has limitation of maximum output. By reducing impedance of AK100, there could be deterioration of headset and it cause short of circuit. In this case, it consume over 2W electric power and make damage of AK100 circuit.
2. When there is Static Electricity, it can easily damage of AK100. In this case, even it plays but there is no sound.
3. VOC and PL regulation issue will be happed by causing hypacusis and deafness.
4. Even it improves the sound power, it reduces smooth and delicate sound detail of AK100.
With these reasons, we do not recommend reducing impedance or any modification by users.
To prevent such unauthorized modification by end user, we use special screw driver for AK100. But if they carry out any kind of changes or modification by themselves and it cause any problem or issue, we are not obliged to provide C/S or A/S.”
