Hi everyone,

Looking to sell my xDuoo TA-66 desktop tube OTL headphone amplifier. I recently purchased this but I am moving it along because I do not own any high-impedance headphones. Every online review notes that high-impedance cans are where this OTL amp truly shines, so I am hoping to pass it to someone who can maximize its potential.

Condition & History:

* Cosmetics/Function: Perfect aesthetic and functional condition. It is a beautiful unit!

* Usage: The previous owner logged ~50 hours of playtime. I have added fewer than 12 hours.

* Packaging: Will ship securely in its original packaging.

I am offering this with two purchase options (both include CONUS shipping and PayPal G&S fees):

## Option 1: Base Package — $200 Shipped

Perfect if you just want the stock setup. Includes:

* xDuoo TA-66 Tube Amplifier

* Original 6N5P Power Tube

* Original 6N2 Driver Tube (~20 hours of use)

* Power Cable

* 6.35mm to 3.5mm Adapter

## Option 2: Premium "Tube Roller" Bundle — $250 Shipped

Includes everything in the Base Package, plus a fantastic assortment of upgrade tubes and the required adapter (over $120 retail value):

Item | condition/use | value

| 6N2 to 12AX7 Adapter Plug | Excellent | $12 |

| Electro-Harmonix 12AX7 Tube | < 2 hours | $25 |

| Tung-Sol 12AX7 Tube | < 2 hours | $30 |
