Yping, on my system the first DVD source I tried the S/PDIF performed to a lower level than my USB. However the second DVD source I tried I could tell no difference between USB or S/PDIF
Which is best? -I think it depends on each individual USB implmentation. The first USB interfaces in DACs where simply not good. This has improved tremendously and the latest from Schiit is extremely good.
Also, I have put effort into ensuring my USB interface performs to it's best ability by using a split USB data/power cable and seperate USB power supply, so it performs to the highest level possible - I think.
Without taking the approach above, a simpler USB implementation is more likely to suffer from issues pertaining to both the stability of the USB power supply and the noise pollution present in many conventional USB cable designs - whereas adopting a S/PDIF approach immediately eliminates the USB's power related issues.
Incorporating a USB-S/PDIF converter is one way to improve on the USB interface if you prefer - personally, I do not think introducing one into my particular implementation would be of any benefit, but I could be wrong.
Re: digital jitter and analogue noise - I wouldn't say either issue is "easier to overcome", since there are different issues with each digital interface and on the analogue side, other than noise, you always have that ethereal "component/cable synergy" to consider.
I think we are getting more knowledgeable in both realms and will one day nail the perfect solution - having said that - I'm still working on my turntable after 34 years :-)
Re: HDMI - I use it for my A/V system only, no experience with this on my audio system.
Re: 12s - no experience with this.
