Desperately seeking some advice/tips for my S.M.S.L. SU-9 DAC
Hello All,
So I just upgraded (?) my DAC from my Schiit Audio Modi to the SMSL. SU-9. I had read such great reviews on this unit so decided to pull the trigger. I figured my Sonus Faber Sonetto III’s were worthy of a better DAC (not that there’s anything at all wrong with the Modi).
However I didn’t really realize the SMSL had so many different setting options. You know sometimes less is more :(. First question should I turn the SMSL off when not in use?
So now settings questions. I have the SMSL connected to an old Pioneer 101 disc cd carousel via a Voodoo Cable optical. I know I know about the cd player but I love the convenience the old carousel changers offer. As this DAC offers multiple settings any advice here on each of the settings and choices below? I truly have no idea as I have never seen settings like these and I honestly don’t even know what most of them mean and the manual is NO help:
PCM Filter:
Fast Linear
Slow Linear
Fast Minimum
Slow Minimum
Fast Hybrid
Apodizing
Brickwall
DSD Filter:
47kHz Cutoff
50kHz Cutoff
60kHz Cutoff
70kHz Cutoff
Sound Color:
Standard
Rich 1
Rich 2
Rich 3
Tube 1
Tube 2
Tube 3
Crystal 1
Crystal 2
Crystal 3
DPLL:
Range 1-15 (though the manual says lower for better de-jitter) - do I even need to play with this? Default setting is 7
I would sincerely appreciate any advice on any of this. Thank you so much in advance...
Best Regards,
Brian
Sorry rest of associated equipment-this is used as a second system 2 channel audio/tv/movie system:
Marantz 1510 receiver (used as pre)
Bel Canto REF 501S stereo amp
Transparent RCA's from SMSL to the Marantz
That’s a lot of options!
I would start with The ones recommended by @djones51 above me. Standard for sure… turn everything off that you can. Listen for a couple to few months. Get to really know the sound. Then make one change. If not good or no difference go back to your initial settings. Then listen for a couple weeks. Then try something else. Flipping around is just confusing… at least to me. Long term listening sets a reference point. Ultimately you have to try.
