rushofblood recieved modded DX90 today. We will wait for review :)

The affected parts are: Common power supply. DAC power supply. Current-to-voltage converters. Output buffers. Removed redundant decoupling capacitors.

I will wait your parcell 

Quote: In many devices schematic modificatications is more important than playing with opamps and capacitors. It's not a magic, it's just The Art of Electronics  For example my "beggar" mod for DX50, it need only 2 resistors and 4 peace of wire 

Really, power supply in DX90 it's not a simple. Power supply it;s some dc/dc converters, linear and switch. Battery replacement may be important for part of this, but isn't important for other.

It's only one chance for getting my mod - sending DAP to me for mod.

Quote:     This Amp based on MAX97220, not UDA1380. UDA1380 - DAC/ADC/headamp in Iriver 120/140/320/340.

Quote: No, it's just rerouting board for small size. 1st board was 16*22 mm 2nd 23*10.5. in both board I used MAX97220 amplifier.

Iriver H10 (20 GB) modification also possible. Mod is possible for any player, question only is placement inside.
