AUDIOTRAK DR.DAC2 DAC + Headphone Amplifier with Box and Optical Cable

I used it without any particular problems, but I haven't used it for the past few years and it has been stored at home, so I am listing it for sale.

The items for sale are the AUDIOTRAK DR.DAC2 main unit, standard AC adapter, and USB (USB-B) cable. All of these have been used by me and are pre-owned.
There is no instruction manual, but the operation is simple and you can basically use it by just connecting it.

In addition to the accessories, I will include a power cable (so-called eyeglass cable) and an optical cable as a bonus.

The main features of the DR.DAC2 are:

- Equipped with a DAC (TI Burr-Brown PCM 1798) with 24bit 192kHz, 123dB dynamic range, and THD+N: 0.0005%.
- Equipped with dual headphone outputs.
- FDO type triple OPAMP circuit.
- Uses high-quality film capacitors.

By the way, the price at the time was 44,980 yen.

Please check the 5th photo for the internal OP-amps.
Since the headphone amplifier can be opened by removing just one screw, it is recommended for those who want to enjoy music by replacing the OP-amps.

It also supports optical input and I believe it is a DAC that can still be used.
As it is not new, I believe there may be some age-related degradation in the analog circuit part regarding sound quality.
Recommended for those who often listen to music, watch movies, or play games with headphones, or for those who want to enjoy replacing the OP-amps.

Please understand that this is a used item before purchasing.
