Topic: Adi-2 Pro Fs - A/D-conversion: perceived sonic difference - fake news?
Hi,
- I have the adi2 pro fs in preamp mode.
- I have high end microphones and outboard gear, the signal path is fully analog, resulting in a two channel mix sent to the adi.
- I have closed back headphones connected to ph 3/4.
- I sing and play acoustic guitar, the test is performed in real time, i.e. nothing is recorded.
- No eq, loudness,t/b, crossfeed enabled.
- Analog input:
- AD-filter sharp - will automatically change to slow above 192khz.
- AD Conversion - DSD (changes to pcm in lower sample rates I believe, thought I read this somewhere in the manual, cant't find it now though...)
I'm switching sample rate on the fly, and my mind blows right through the roof and up to the sky...
- 44.1 - sounds like crap.
- 96 - sounds pretty good and it's now kind of scary to realize just how bad 44.1 was.
- 192 - sounds better than 96.
- 768 - (analog in -> dsd256 -> pcm768 -> ph 3/4) sounds amazing! Even better than 192 ( impossible, right? :-) )
Furthermore, with 768 kHz sample rate selected, switching between pcm and dsd, makes a difference. Dsd sounds better, and dear I say it, more analog.
1: analog in -> dsd256 -> pcm768 -> ph 3/4
2: analog in -> pcm768 -> pcm768 -> ph 3/4
To be clear, the sound differences are (for the most part) to big to be fantasies, but maybe there are more things going on that I miss? If not, I can never ever go back to pcm for recording...
What do you think? Are things changing that I'm not aware of?
Cheers,
Lars
