I really appreciate you taking the time to help me with this.
Now: out of my headphone jack, no hum or noise even at full volume which surprises me.
To Luxman 10wpc Tubes to Ar2ax speakers I just restored. Those vintage speakers have Level Controls for the mid and tweeter, I replaced them and adjusted in place. I sit dead center and get terrific imaging for both audio and music videos.
I started this because it's the last potential improvement I could think of in my office. I don't know what limitations are imposed by the motherboard/audio codec/dac somewhere/to headphone jack. It just seems a dinky headphone jack ought to be easily beaten.
I'm gonna buy a half height usb 3.0 card, I could use more ports in any case.
Then try the Topping D10s from Amazon you recommend.
1. USB input on Topping looks like a standard usb printer cord, Correct?
2.12 ft run from PC to Luxman with some slack: Longer usb/shorter RCA or short USB/longer RCA? Really doesn't matter?
3. says 'Latest' Windows. I have 10 home, I do not want to upgrade to 11. 10 presumably works?
4. 'Thesycon Installation'? Different Player?
I'm now using Windows Media Player for the small amount of music I have downloaded (whatever comes when I buy a new LP).
YouTube and Pandora my primary sources, I see their windows, is Windows Media Player in the background playing those streams?
After Thesycon Install, still use Windows Media Player?
