I could use a little input on the following:
I play the majority of my music from my computer through my receiver (H/K AVR135). I have a Turtle Beach - Santa Cruz sound card which allows me to output in either digital or analog. I wanted to switch over to the digital output of the sound card. I was looking at the Turtle Beach website and it gave the following stats:
Analog (A-A):
-------------
Frequency Response: 10Hz - 120kHz (-3dB)
SNR: 96dB FS A-weighted.
THD+N: (-3dB): < -91dB FS (0.0027%).
Crosstalk: -105dB @ 100Hz
Digital Playback (D-A):
-----------------------
Frequency Response: (-3dB) @ Fs = 48kHz: 10Hz to 20kHz
SNR: 90dB FS A-weighted
THD+N: (-3dB FS): < -87dB FS (0.004%).
Digital Recording (A-D):
------------------------
Frequency Response: (-3dB) @ Fs = 48kHz: 10Hz to 20kHz
SNR: 93dB FS A-weighted
THD+N: (-3dB FS): < -84dB FS (0.005%).
Digital Output: 48kHz PCM audio or Dolby Digital(R) AC-3 for external decoder.
----------------------------------------------------------------------------
For those who wonder:
The SNR on the Analog is 96 dB whereas the SNR on the Digital is 90 dB & 93 dB. The A-A number is always higher (and basically meaningless since it measures only the analog loopback i.e. line in to speakers).
Do the above numbers indicate that the quality is better through the analog output? I just don't get it.
Any ideas?
