CEntrance Mini-M8 Portable iDevice/USB 24bit/192kHz DAC/Headphone Amp The best just got better With its unique combination of sound quality, portability, and function, Mini-M8 sets you apart to experience Audiophile sound anywhere you are. Reclaim your freedom from the confines of a home system -- experience your music anywhere. Mini-M8 (pronounced: "mini-mate") is thinner and lighter than our best-selling HiFi-M8, making it our most portable DAC/Amp with the longest battery life. Yet, despite its slimmer size Mini-M8 packs additional features, such as four inputs, DSD playback and more! Mini-M8 features a laptop input with 24-bit/192kHz asynchronous USB interface, an iPhone/iPad/iPod input compatible with both 30-pin and lightning-based devices, a SPDIF optical, and a SPDIF coaxial input. That's four inputs in total! This unheard-of flexibility allows you to connect your Mini-M8 to any Digital Audio Player and be confident that your amp remains future-proof, even if you change DAPs later.
