So I should just get a better headphone (HD 600 or Fidelio) and plug it right in the sound card? no need for amps or anything right?
You said you wanted to upgrade and the Magni amplifer should be a more powerful then the Fiio E17s amp.
I would guess the Titanium HD's PCM1794 DAC chip is better then the E17's WM8740 DAC chip.
Your are correct that using an external DAC, connected with USB or optical or coaxial, keeps electrical noise from inside the computer case affecting the DAC.
Usually people buy an external DAC because it's usually better then what is inside the computer.
But I believe the PCM1794 is about the best DAC chip you can stick inside a computer case.
I would assume you bought the E17 because you also had a use for a DAC/Amp you can travel with.
The Titanium HD's headphone jack is fairly decent at driving headphones, even if it may not be considered a true headphone amplifier.
The Magni amplifier is better at driving headphones then the Titanium HD's headphone output.
Also plugging a external headphone amplifier into the Titanium HD' RCA jacks allows the Titanium HD to use all three of it's op-amps (operational amplifiers) and the Titanium HD can send CMSS-3D headphone surround sound thru it's RCA outputs.
I guess I would try the Philips X1/28 Fidelio, it's is only 30-Ohms, so the E17 or Magni can easily drive it.
