Product Code: Luxury & Precision L3

฿15,850
  • L3 portable balanced HIFI player
  • Portable HIFI players hard decoding a variety of DSD format
  • With a balanced interface, up to 110DB channel separation
  • Low backgroud noise, especially for high-sensitivity armature earphone
  • USB DAC function , don’t need additional driver


Better user interface

  • Music playback interface display more information about the music


More user-defined audio settings

  • there are 2 user-defined buttons at the  top of L3 , C1 and C2 ,  the user can easily set up a variety of functions: EQ, play mode, SPDIF, etc., quickly switch a variety of settings, enjoy the music freely


About 120DB low background noise


USB DAC

  • USB DAC function to make all kinds of mobile phones and computers become the sound source, and L3 becomes amp decoding machine


Through the L3, phones can be also balanced output

  • L3 with USB DAC amp functions as a decoding machine, in addition to through the Phone out, Line out and SPDIF out output, but also through balance output, so that audiophiles can enjoy the true balanced sound and no background noise .


Separation

  • Few of player can do 110DB (32 ohm load) separation index in the field of portable HIFI player


Hard decoding DSD format

  • L3 player hard decoding DIFF, DSF, DAT and ISO and other four DSD format music files


Dual DAC

  • Two classic old flagship DAC, CS4398 are working together both in single-side or balanced output


1812M coprocessor

  • 1812M coprocessor number crunching ability is the secret of L3 supports multiple file formats
