3.2dB (G=H) Max Input Level 3.4V
Ifi nano IDSD BL:
Headphone Amplifier
Amplifier: Dual Mono 2 x 285mW Direct Drive, coupling capacitor free circuit for highest fidelity
Volume Control: 3.5mm TRRS with Balanced compatible wiring
Dynamic Range(including DAC): > 109dB(A) @ 3v (Direct)
> 107dB(A) @ 0.5V (iEMatch®)
THD &N (@ 125mW/30R): < 0.005%
Max. Output (<10% THD): > 3.5V @ 600Ω Load (Direct) (20mW/600Ω)
> 2.9V @ 30Ω Load (Direct) (285mW/30Ω)
> 1.7V @ 15Ω Load (Direct) (200mW/15Ω)
Output Impedance : < = 1Ω (Direct)
< = 4Ω (iEMatchsup>®)
Channel Separation: > 79dB @ 600Ω Load (Direct)
> 79dB @ 15Ω Load (Direct) (1kHz, TRRS plug Balanced wiring)
Line Output
Dynamic Range(Line): > 109dB(A)
THD & N(0dBFS Line): < 0.004%
Output Voltage(Line): : 2.15V (+/-0.05V)
Output Impedance: < 240Ω
Channel Separation: > 99dB (@ 1kHz)
Jitter(correlated): Below test set limit
Dimensions: 96(l) x 64(w) x 25.5(h)mm
Weight: 139g (0.31 Ibs)
Warranty period: 12months
The Fiio Q1 MK II has better THD+N and a better dynamic range at half the price, the nano has a better amp but i don't really need it and can get an A5 separately. I also hope Ifi releases the frequency response of the nano.
