Purchased in December 2024 from a Hi-Fi audio website overseas and used until now. The condition is good, and the operation has been confirmed to be excellent, producing very good sound. I loved it and used it with care, but I am selling it because I will be receiving a higher-end model from an acquaintance. The main inputs were I2S and Optical, and the output was XLR balanced. ※ While removing the cables for this sale, the cover of the Optical input terminal came off, and the Optical input is no longer recognized. Other inputs, USB, I2S, Coaxial, and AES/EBU, have been confirmed to be working. As a countermeasure and bonus, I will include a TOSLINK and Coaxial converter. Even compared to the Pegasus, a higher-end DAC from the same company, the sound quality difference doesn't justify the price difference of over $500, according to evaluations. It is a highly-rated product by engineers and users alike. As it is a volume-less DAC, it is recommended to connect it to a high-quality preamplifier. It's not often that this product is listed, so why not take this opportunity if you haven't experienced an R2R DAC? The package includes the main unit, power cable, TOSLINK and Coaxial converter, USB cable, Optical cable, and the original box. I will pack it carefully for shipping. ・I will try to ship as quickly as possible. ・I will respond quickly and sincerely, so thank you. smsl topping gustard denafrips ladder holo audio
