I think it's on the cheaper side for the market! I'm selling it to upgrade my equipment. It's a gen1 Thunderbolt model, HERITAGE EDITION. It has been transferred and is fully functional. The top panel, which looks dirty, is a protective seal that I haven't removed since I bought it. I'll 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 items: Power adapter, Thunderbolt cable
