Dedicated 3.5mm Source to Headamp Cable: Yarbo Audiophile Cable with 3.5mm to 3.5mm Stereo Plugs.

For the Source and portable headphone amplifier interconnect I use a very substantial cable called the Yarbo Audiophile SY-211OL which 1 m long and is terminated at both end swith very high standard gold plated 3.5mm stereo plugs. Cable diameter is about the same as a AAA battery. Of course with this cable the best audio signal transfer is obtained.
