※Price not negotiable. I believe this is a good price compared to the market! I am selling this because I am upgrading my equipment. This is the gen1 Thunderbolt model, HERITAGE EDITION. It has been transferred and is fully functional. The top panel, which appears dirty, is a protective seal that I have not removed since I purchased it. I will also include a Thunderbolt cable, which is normally sold separately, as a bonus. The high-quality audio interface, Apollo Twin X, is equipped with a DUO CORE processor and delivers professional sound quality. - Model Name: Apollo Twin X - Processor: DUO - Included Accessories: Power adapter, Thunderbolt cable
