E5 Specifications
Following information are what I have gathered and translated from Fiio BBS (Chinese section):
Samples were sent overseas to selected Headfiers (those possess other portable amplifiers for comparison) for trial before sending samples to customers in China in order to beat Christmas deadline. Most likely it will be launched in December before Christmas. Because red faceplate mask out red LED, thus most likely only black case with white faceplate will be launched.
Specification (as of 3-Nov-2008):
Output power: 150mW into 16 ohm / 12mW into 300 ohm
S/N ratio: >= 98 dB (A-weighted)
Distortion: < 0.009% (10 mW)
Frequency response: 10 Hz - 100 kHz
Headphone impedance: 16 ohm - 300 ohm
Weight: 26 g
Power supply: built-in 200 mAH lithium polymer battery
Dimension: 44mm x 38 mm x 12.2 mm
Pre-amp: OPA2338UA (TI)
Power-amp: TPA6130A (TI)
Accessories: 20mm and 60mm 3.5mm interconnects x2, 60mm USB cable x1
Take note of the opamps used (OPA2338UA/TPA6130A), any comment on sonic characteristic with these two opamps ?
