Modded ibasso

For sale iBasso DX90 portable audio player, very well taken care of (used only with case and screen protector), boxed and with original accessories, in excellent condition - almost as new. The amplifier stage has been modified in order to achieve superlative performance. Tested with a professional dScope audio analyzer, the modded player measures 0.00079% (-102dB) distortions under a 16ohm load and at a 500mV output! This is pretty much state of the art in professional audio territory, let alone for a portable device. For reference, under same conditions original schematic achieves 0.022% (-73dB), which is pretty good already but much below what the DAC chips can support and what can be squeezed out of this gem. Note that the power consumption increased by around 10-15% following the mod. 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 will reset the player to factory defaults before shipping. Main Features: - Bit for bit playback, Support up to24Bit/192kHz - Dual ES9018K2M DAC - Built-in 10V Voltage Swing Headphone AMP - 2.4" IPS Screen (320*240) with Capacitive Touch Panel - Up to 24Bit/192kHz Mini Coaxial Output - 3.5mm Headphone Output, and Line Out - Three Physical Buttons (Previous,Play/pauses, Next) on The Top Panel - 256-Steps Digital Volume Control - 8GB Onboard Flash Memory - Support for SDXC and SDHC MicroSD Card,up to 2TB.

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. Main Features: Dual ESS Sabre ES9018K2M DAC Chips 2.4" IPS Screen (320*240) with Capacitive Touch Panel Up to 24Bit/192kHz Mini Coaxial Output 3.5mm Headphone Output, and Line Out Three Physical Buttons (Previous,Play/pauses, Next) on The Top Panel 256-Steps Digital Volume Control 8GB Onboard Flash Memory Support for SDXC and SDHC MicroSD Card,up to 2TB.

For sale iBasso DX90 DAP, with original box and accessories, in excellent condition (has always been used with protective screen and case), working perfectly. While pretty good in its original form, iBasso engineers did cut some corners and the player does not reach its full potential. As such, the player has been extensively modified in order to improve performance:  - power supply and DAC stages have been redesigned in order to reduce the overall distortions and noise level, in particular at lower frequency where the original suffers the most (around 5dB THD+N improvement at 1KHz, 30dB (!) improvement at 20Hz)  - output buffering stage has been modified in order to improve performance with lower impedance earphones (with 16ohm load THD+N is improved by approx. 30dB) Measurements with a professional audio analyzer show that the modified player is reaching excellent performance under real life test conditions (line out: -105dB THD+N across pretty much most of the audible frequency spectrum, headphone out: -102dB THD+N while delivering 500mVrms under a 16ohm load). Included:  - DAP  - Original battery (in very good condition) + new spare battery  - USB cable  - Coax SPDIF out cable  - Burn-in cable  - Silicone case  - Spare screen protector (one already applied) The item will be carefully packed and tracking number will be provided. Shipping out of France, fast delivery and no taxes for destinations within EU.
