PC!-e x16, Half Height Sound Card: OBVIOUSLY better?

I doubt you'll hear much of a difference if you use the audio converter in the second link and it might very well sound worse. These kinds of cheap boxes usually have a lot of corners cut.

If you're happy with the sound you're getting, there's really no reason for a change.

If you want to test the waters, I suggest getting a Topping D10s (USB input only). It's $109 on Amazon and offers respectable performance. A JDS Labs Atom DAC+ would also be a good choice, but the return policy isn't as generous (pay for return shipping + 15% restocking fee).

yage,

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.

Questions:

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? 

Thanks, Elliott

1. Yes it's a standard printer cord. Make sure the cable is rated for USB 2.0 speed to support playback of sampling rates higher than 96 kHz.

2. I would go for a longer USB cable and shorter RCA. USB 2.0 is limited to 5 m or ~16 feet. I think the Amazon Basics cable comes in a max length of 10 ft. which would probably work well in your setup.

3. Windows 10 is fine.

4. Thesycon is the driver for the USB interface on the DAC. It's normally unnecessary to install a driver if you're using Windows 10 / 11, but if you're having trouble getting the DAC to work, then installing the driver would be a possible solution.

If you're only listening to downloads that come with an LP purchase, Windows Media Player should be fine. If you ever want to listen to hi-res downloads (e.g. from HDtracks), then I highly recommend using foobar2000 with the WASAPI component added. It's free and works well.

OK, I got a plan and all the answers thanks to your help!

ordered both card and dac, amazon, b here tomorrow, amazing
