Thank you for viewing. This is a set of Furutech's wall outlet GTX-D NCF(R) and Audio Mijinko's original outlet cover. In my personal opinion, I think this is the best wall outlet available. The basic performance is amazing, including the number of sounds, resolution, and soundstage width! As a side note, although it doesn't directly affect the sound quality, I was a little surprised when I first plugged in a plug and it connected as if it were being sucked in (lol). The manufacturing precision is high. As a bonus, I will also include Audio Mijinko's wooden original outlet cover. As a precaution, you may already know this, but a licensed electrician is required to replace a wall outlet, so if you don't have a license, please have a qualified person replace it for you. I looked for the original box for the outlet but couldn't find it, so I couldn't include it. Sorry (sweat). Thank you for your consideration!!
