Best audio output/ input

[Yoo Song Won]

So I'm wondering which on of the four audio output/ input devices are the best:

 

Optical Digital Toslink Cables

 

USB Cables (A and B)

 

HDMI Cables (Though, I'm only thinking about the audio and not the video output as I'm just concentrating on audio quality) 

 

Analog Cables

 

Which one is the best? I'm planning to use one of them to use for my new Sennheiser HD650 and an amp I'll be getting soon.

Why don't you use an audio jack?

Isn't that just an analog cable? I heard they're not the best for audio.

You heard wrong.

 

If it's just an amp, you can't connect it via a digital interface, period. What amp is it?

It's the SMSL SD793II. I'm planning to use optical digital for it since it has no USB port...

That is a DAC/amp. You have no choice but to use Optical SPDIF since that is the only input available on that unit.

I'm guessing that the Optical SPDIF is fine then. I read that there isn't much difference in terms of audio quality between this and the other audio devices.
