About the U2 w/Sbooster
The Lumin U2 is a transport-only unit featuring a built-in linear power supply, which is a significant upgrade over many other digital transports. It includes an ultra-low-noise rectifier and linear regulator, along with an extra large toroidal transformer. The U2 supports DSD512 and PCM768 playback and features four exceptionally low-phase-noise crystal clock oscillators. For further enhancement, users can opt for an external power supply upgrade using the Sbooster BOTW P&P ECO MKII, which requires the Sbooster Lumin Connection Kit. This kit allows users to replace the internal power supply with the external linear power supply, potentially improving sound quality by reducing noise and enhancing the stereo image.
