FS: Brand new, unused iFi SPDIF iPurifier, opened only to take a photo. The unit reclocks and galvanically isolates. I use one between an Oppo 203 and a Lampi dac - previously a DSD - so this one is extra.* See https://ifi-audio.com/products/spdif-ipurifier/ for product info. They go new for $149. Asking $99 shipped CONUS + PP (or use f/f). Feedback here and Audiogon, Audiomart, and eBay(genegold99), etc. * I also have a Core Audio Technology Kora LPS for sale, which improves the iFi's sound quality – see https://www.usaudiomart.com/details/649542582-core-audio-technology-kora-linear-power-supply-lps/).
