※ Please check the profile before purchasing. Thank you for viewing. This is a set of the Cayin N6ii DAP T01 and the audio motherboard E02. I am selling it because I purchased another DAP and haven't used this one for a long time. I purchased the T01-equipped body new around October 2021, and then purchased the E02 used. I had the standard case attached, so there are no noticeable scratches on the main body. The case has some signs of use, as I had a portable amplifier wrapped around it. There are no noticeable scratches on the motherboard either, but there are some minor scuffs from insertion and removal. I checked the operation of all boards and terminals before listing, and they were working without any problems. I haven't checked the operating time in detail, but it was about 1% in 10 minutes with the most fuel-efficient E02's high gain, so I think you can use it without any problems. However, please note that the power consumption varies greatly depending on the DAC and gain. The operation is slower compared to recent smartphones and DAPs, but I was able to play Spotify properly. You can enjoy multiple sounds with one unit, so how about it for an entry-level or sub-DAP? ※ The A02 in the photo is not included as it was sold separately. Please be aware.
