MODDED (!) IBASSO DX90J (JAPAN EDITION) HI-RES DUAL SABRE PC À PARIS

For sale iBasso DX90J (Japan Edition) portable audio player, very well taken care of and in excellent condition. This is a great player that has developed quite a fan base given its quality, size, usability and versatility. In its Japanese incarnation (DX90J), it is supposed to have undergone additional tweaks and presumably it sounds a tad better than the international version (DX90). However, both DX90 and DX90J deliver rather modest performance with IEMs/low impedance headphones in their original form. Therefore in order to unlock the full potential and achieve superlative performance under any conditions, the player has been extensively modified. Tested with professional dScope audio analyzer, the modded player measures -101.3dB (0.0006%) total harmonic distortions under a 16ohm load at a 500mVrms/16mW output (compared to -58.5dB / 0.1189% before modding)! This is pretty much professional audio territory performance from a portable device, measured under real use conditions. Note that as a result of the modifications, power consumption increased by approximately 10-15%. Rockbox open-source alternative firmware has been installed (parametric EQ, dithering, gapless playback etc.). The player can be booted either with the original firmware or with Rockbox, should you prefer to use only the original firmware send me a note and I will reset the player to factory defaults before shipping.
