Computer for home audio


I am using my home computer for driving my audio system while watching You Tube Videos. The computer is a older Dell just using the audio output 1/8" from the onboard audio.Is there an improvement to this availe?

I have something similar. One thing I do is keep the browser tabs to a minimum, especially on web sites that have a lot of video ads. These sites take up CPU cycles.

I also use a Sonare microRendu that isolates the computer noise from the DAC. It is an Ethernet-2-USB conversion device. I have learned recently that I can improve on this because there is some noise on the Ethernet wire that gets into the DAC. However, the microRendu sounds very good in my setup. There always the option of making an OPTICAL network from your computer to the DAC to lower or eliminate this Ethernet noise. Sonare also has a solution for this which they market as SystemOptique (a few hundred $$).
Why anyone uses a computer to stream music to a high end system today is a mystery. There are too many better available options now.
@ozzy62      Ozzy just read your comment about computers and music which is what I now use exclusively. I have built a bespoke computer for nothing else but music and it cost me a bomb but is so good that I eventually sold my Gryphon Mikado Signature because the PC blew it out of the ball park.
