Hi everyone, I am a musician and I don’t have any knowledge about impedance, voltage, sensitivity and so no. However, I can see that my old interface has some difficulties to drive my AKG702 headphones (I know I could use other headphones that I have or buy a DAC but I am not interested in both).
Besides, it is time to change my old interface, I am considering two options: the first one it is my favourite but sadly I am not sure if it can drive my loved 702 with any of its 3 heaphone output modes. The issue with the second interface is that it lacks another important feature with me and I would only buy it if the first one is not good enough.
Any help would be appreciated, I don’t want to have an interface which can’t drive comfortably my favourite cans again, I don’t want to make a wrong decision.
I can give all the info I could find about the 3 devices:
AKG 702 SPECS.
Impedance: 62ohms
Sensitivity (dB SPL/V @ 1 kHz) 105
FIRST INTERFACE SPECS
This interface brings you three different modes to use with your headphones:
MODE A Standard.
MODE A. for headphones that specify their performance at 100 dB/mW or higher.
MODE C. for headphones with a an impedance of 250 ohms or more.
Mode A specs
Frequency Response 20Hz - 20kHz +/-0.02dB
Dynamic Range (A-weighted) 112dB
THD+N (-1dBFS) (@1kHz) 0.005%
Maximum Output Level +10 dBu
Output Impedance <1 Ohms
Mode B specs
Frequency Response 20Hz - 20kHz +/-0.02dB
Dynamic Range (A-weighted) 108dB
THD+N (-1dBFS) (@1kHz) 0.001%
Maximum Output Level -6 dBu
Output Impedance <1 Ω
Mode C specs
Frequency Response 20Hz - 20kHz +/-0.02dB
Dynamic Range (A-weighted) 112dB
THD+N (-1dBFS) (@1kHz) 0.001%
Maximum Output Level +18 dBu
Output Impedance <1 ohms
SECOND INTERFACE SPECS.
maximum output level: 18.5dbu=0dbfs
thd+n @ -1dbfs (1khz): 0.0006%, -104db
dynamic range: 124db a-weighted
crosstalk: -117db @ 1khz, -101db @ 10khz
frequency response: +/- 0.2db 10hz to fs/2 (nyquist)
output impedance <50 ohms unbalanced
max level into 30r 2.63v peak, 1.87v rms, 232mw
max level into 60r: 4.28v peak, 3.03v rms, 295mw
max level into 600r: 7.91v peak, 5.6v rms, 104mw
