Tokyo Sound SOUND Valve X SE Vacuum Tube Headphone Amplifier - Headphones New, Unopened, Long-Term Storage. Original price: 77,000 yen. Discontinued product. Invoice included. ⚠️ Since there was no comparable market price for a new, unopened item (used items are around 30,000 yen?), I'm currently thinking of lowering the price to 67,900 yen, considering past price suggestions and rarity. However, if you have a price in mind, please use the "Price Reduction Request" function or the comment section. ※ I already owned one at the time, but around the beginning of 2013, there was information that Tokyo Sound might go bankrupt (unfortunately, they actually did in 2013), and because I liked it, I bought another new one from Fujiya Avic and kept it in storage in case the first one broke. The unopened item has been stored for over 10 years since purchase, but the first one shows no signs of breaking, so I thought it might be pointless to keep it, and I decided to list it if there's a demand. ※ Basically, it's an amplifier that leans towards the low and mid ranges. You can enjoy the change in sound by replacing the vacuum tubes. At the time, changing the standard Electro-Harmonix tubes to JJ or Sylvania tubes was highly regarded. You can also replace the power cable and fuse. (Please read!) ⚠️ Since it's an unopened item, I can't take pictures of the inside, so I also took a picture of the invoice from Fujiya. The 8-digit number (serial number, information from the box of the same item currently in use) sticker affixed under the barcode on the box and the registration number listed on the Fujiya invoice are the same (Photo 5, blue). ※ I have hidden part of the name of the person in charge and personal information, as well as the first and last digits of the 8-digit serial number (Photos 2-5). ※ If you purchase, I will ask if you need a copy of the invoice with personal information redacted. ⚠️ The top of the box says "Glass parts...", but I didn't hear any sound when I gently moved it from side to side, so I don't think it's broken. ⚠️ Although it's a new purchase, please understand that I cannot guarantee the condition or operation of the contents due to the long period of being unopened. In addition, since the manufacturer has gone bankrupt, I would like those with the technical skills to handle any potential issues to purchase it. (Apparently, a company called I-Products handled repairs, but I don't know if they still provide support.) ※ I will pack it with as much protection as possible for shipping.
