Lumin U2 mini Following in the footsteps of one of our most popular models, LUMIN U2 Mini introduces our all-new processing system, delivering greater flexibility and future-proofing. Capable of upsampling and downsampling all the way from 44.1kHz to 384kHz/DSD256 and supporting playback of DSD512, LUMIN U2 MINI is the perfect streaming partner for your DAC. Main features Transport-only LUMIN for combination with an external DAC The first LUMIN to feature our all-new processing system Faster processor provides greater resampling flexibility - upsampling and downsampling to every supported format up to DSD256/PCM384 to hit your DAC's sweetspot Increased capacity for future updates New surface finish taken from the high-end P1 Quad native clock system for precision timing 5 types of digital audio output including USB MQA Decoding Roon Ready Leedh Processing volume control Builds on the massive success of U1 Mini Completely new processing hardware and software deliver improved features and increased resampling flexibility while retaining all the musicality that was noted in so many outstanding U1 Mini reviews. Key hardware features carried over from U1 Mini include the quad clocking system and 5 different digital outputs with USB now capable of up to DSD512! The new model is also finished in a new silky surfacing process taken from our high-end P1 that is less susceptible to finger marks and easier to clean. All the usual LUMIN refinements From MQA to DSD, FLAC to WAV, LUMIN can play all the high-resolution formats you could ever want Native support for TIDAL, Qobuz, Spotify and AirPlay, giving you access to tens of millions of songs The unique and intuitive LUMIN App described as "fantastically intuitive and easy to use" by What Hi-Fi LUMIN programme of continuous development that has seen Apple Silicon Mac support, TIDAL Connect, FLAC Lossless Radio and TIDAL Suggested/Related tracks added in 2021 alone.

Apple Mac with Apple Silicone OTHER: Leedh Processing lossless digital volume control Compatible with LUMIN Infrared Control Package Programme of Continuous Development – Firmware-upgradable for further features LEEDH PROCESSING Lossless volume control for all LUMIN players. LUMIN users now have the option to use (at no additional cost) Leedh Processing Volume Control instead of the default processing algorithm. What is Leedh Processing? An innovative new digital volume adjustment algorithm that eliminates rounding errors. Modifies the digital signal amplitude exactly, without any changes to its shape and free from any kind of information loss. Uses more efficient whole number volume values to maintain audio information integrity during subsequent DAC conversion. Low processing power requirements free up cpu resources. Removes need for a pre-amplifier in more systems. Improves the quality of the signal into LUMIN Amp. Leedh Processing is an innovation of Gilles Millot of Acoustical Beauty, a French manufacturer of high end loudspeakers who already holds several patents for his innovative designs and technologies.
