Selling my line out docks.
Both have very unique sound signatures. I am the original owner and bought both brand new.
ALO 18awg Jumbo Cryo DockSell for
$100 shipped CONUSA. Paypal included.This has a very full, warm sound with just the right kind of detail. My favorite LOD for its tonal attributes. Best copper wire one can probably buy.
Uses a Canare F12 miniplug and a larger dock connector.
Revelation Audio Cryo Silver Reference Line Out DockSell for
$65 shipped and paypalled CONUSA.
This has a faster sound with oodles of details. The bass is tight and accurate. The highs sparkle. Uses a slim dock connector and gold miniplug.

Here is an awesome headphone amplifier to go with it. It is a DAC and headphone amp so it can hook up to your computer for high quality audio. Use the Line Out dock with your IPOD and this amp for a portable high quality solution.
