SPDIF Optical and RCA Out Plate Cable Bracket for ASUS Gigabyte MSI

I recently built myself a fanless and passively cooled media PC using the ASUS H310I-Plus R2.0 mini-ITX motherboard, using it as Roon Core to output bit-perfect digital audio into my I2S NOS R2R DAC. The DAC uses external digital audio interfaces for USB and S/PDIF connection, buffering and converting the signal into I2S for input into the DAC's main unit where it is reclocked and converted into analogue output. I was previously using the USB out from another Roon Core, but wanted to compare the USB to S/PDIF output. And I am very glad I did. This bracket is easy to install and is well made. One has to look into the motherboard's documentation to locate the S/PDIF pin outs on the board, connect the cable, connect the other end to the pins on the small PCB connected to the bracket, install the bracket into the PC's chassis and enjoy. On the ASUS board there are 4 S/PDIF pins - +5V, spacer, signal and ground. Other motherboards may only have 3 pins out, omitting the spacer, so be careful how you connect the cable. The unit will need +5V to work. For the last several weeks I have been using optical TOSLINK out of my PC and into the DAI of my DAC, and to my tinnitus-plagued ears the sound clearly is better compared to USB into the same DAC. Maybe it's only expectation bias at work in my mind, but the bracket unit is working very well and with TOSLINK at least I can expect to be not bothered with electrical or RF noise.

This hard-to-find card brought new life to our old Bose computer speakers. It works great, but it could definitely use some instructions—be sure to look up guidance online to ensure the pins are oriented correctly on the board.

If you know how to install an expansion card and plug in some wires, this is an easy install. Pay attention to the wiring information on this page and your motherboard manual to make sure you plug the wires in correctly (hint: brown is the "positive" spdif lead and black is the ground). It should otherwise be self-explanatory. Make sure, of course, that your motherboard has the SPDIF connectors that this will connect to!Once installed, in Windows I switched to my motherboard's digital audio output (Realtek Digital Output for mine) and it worked! And it sounds amazing coming out of my old soundbar.

I didn't pay attention when I got my motherboard and ended up with a product that didn't have either an optical output or 3 3.5mm audio jackets for 5.1 surround sound. The motherboard did have a S/PDIF header and with this product was able to get the surround sound output I was looking for.But this only works with a full sized PC case and I had to replace my low profile/sff case

I bought this because my computer started making a loud buzz noise when turning the computer on and off. It's about a decade old so I figured it was the power supply started to go or something. I did some research on audio and a lot of articles said PC integrated sound cards have noise issues. I'm not much of an audiophile so it's never really bothered me. I bought this card and connected it to my speakers via an optical cable. I can't believe the quality of the sound I'm getting now. I'm kicking myself for not getting something like this a decade ago when I built this computer. The sound quality is so much crisper than the analogue cable. I bought this one because it has 3 split cables which fits my Biostar motherboard which doesn't have the spacer for the S/PDIF cable. If your PC speakers support digital inputs and your motherboard or sound card have a S/PDIF header I highly recommend getting something like this.

This does what it's designed for, but I learned that digital audio off my mobo produces terrible sound. I switched to a sound card with digital output and it made a huge difference.

If your sound card or motherboard has on-board S/PDIF out but you're stuck with using only Optical digital output, buy this immediately!Why bother? I've been reading for decades now in places like Stereophile magazine that even though "bits are bits", a Coaxial digital output has much less jitter than an Optical output and therefore sounds much better. And after comparing both myself, you'd better believe it - if you're into sound, it should take you all of 10 seconds to hear how much better-sounding a Coaxial digital hookup really is. My main complaint with the Optical output I've been previously using is that the treble never sounded quite right, especially on 24-bit sources - sterile and brittle, that's the only way I can describe it. Switching over from Optical to Coaxial digital gets rid of ALL of that - the difference ain't subtle, as they say.And make sure you grab an actual 75-ohm cable to use with this, normal 50-ohm RCA patch cables won't work...

It works perfectly fine with my motherboard that's really it
