USB from Computer vs Optical from TV ?

post #1 of 3
Thread Starter 

Hello guys,


I've benefited greatly from the amount of information available on these boards, though you'll probably notice that my post ratio says I am much more of a lurker / silent reader than a regular contributor. smily_headphones1.gif


So far I've been listening to music with my cans (Pro900) plugged in the amp (amp being USB-plugged to my computer).


Yesterday I ordered an optical cable to use the optical line out of my amp Ibasso D12 and see for myself if there's a significant improvement from my current set-up.


However, I can't get my head around something. I don't use my computer screen to browse the web / prepare my playlists, it's always plugged on my TV from the computer's HDMI port.


Therefore, I was wondering if you guys could enlighten me on what would be the best set-up as far as general SQ goes:


Computer (FLAC / foobar2000) > USB > Ibasso D12 > Cans



Computer (FLAC / foobar2000) > HDMI > TV > Optical > Ibasso D12 > Cans


I think with the TV being in the middle of this set-up I might lose some SQ on the way but I've got no other option since my computer doesn't have an optical line-out.

What do you think?

The first one. In the second setup, the TV would downconverting the digital signal from the HDMI to S/PDF -> optical -> D12. The more conversion the more jitter and the more degradation of the digital audio.

Thank you for the answer.
Got the optical cable today and the difference (downgrade in sound) was much more noticeable than I thought it would be.

I guess the optical cable would still be handy whenever I want to play video games. tongue.gif


Last question: does it make any difference in getting the sound out from the PS3 optical line-out rather than the TV's (when playing video games)?
