I am making an inexpensive headphone system for my bedroom and I am looking at the SMSL SD-793II DAC DIR9001+PCM1793+OPA2134 Coax/Optical Input + Headphone Amp. I will be running it from an ASUS OPLAY_MINI/1A/NTSC/AS Media Player. Most of my phones are in the 32 to 80 range but i do have a few which are higher. (one 300ohms for example). Will this little amp work properly with higher impedance phones because it does state in the technology parameters [COLOR=FF00AA][COLOR=FF00AA][COLOR=FF00AA]"headphone output :65mW@16ohms;130mW@32ohms".[/COLOR][/COLOR][/COLOR]
Any advice would be appreciated. Thanks in advance ! :regular_smile :

Here are the stated parameters:
Input interface: Optical/Coaxial input(Switchable)
Input frequency:44.1,48,96KHZ/16/24BIT
Output interface:RCA 2 channel output Headphone output x1
Digital receiver: DIR9001 digital receiver
-Very Low Jitter System Clock Output (50 ps Typically)
-Compatible with up to 96KHZ Sample Rate Audio data signals
-Compatible with any types of Delta-Sigma Digital/analog audio change device.
DAC chip: PCM1793 DAC chip
-Advanced Segment DAC,192K/24BIT Digital analog conversion chip
-The famous KECES PCM1793 DAC uses this chip either.
-SNR: >113dB
-Dynamic Range: 105db
-Distortion: <1KHZ%0.0006 below
-Rated output:1.7VPP
-Response frequency:20-20KHz(-0.2db)
-Machine output:<8W
[COLOR=FF00AA]-headphone output :65mW@16ohms;130mW@32ohms[/COLOR]
-Headphone output distortion: 0.01%THD+N@100mW/32O
-OPA2134 Active LPF- straight inserted encapsulation
