Indeed they do, perhaps a little thinking outside of the box may yield some interesting results.
Paying attention to individual mother board regulation, inductor quality, improving clocks all make decent improvements. looking at non USB methods also improves matters no end.
Think of how a computer works, and why many of the actions and results of this happening is counter productive to audio though not necessarily for everyday computer operation.
All good fun though

All good fun though That's thinking inside the box! I believe in that and I'm aware you've had great results from it. I'd love to have a small motherboard with good clean power and good clocks etc. I could do it but something else would have to give. Now if someone could produce a decent product or even kit of parts at a decent price I would do it. I've seen discussions about improving USB but working on the interface chip, supplies etc. Probably this will help but it does seem like trying to fix a technology that's not too suitable in the first place. I2S and the dac in the PC might be best.

The very best USB latency achieve ability is 3-4Msec at the very best, with phase noise issue that cannot be resolved by asynchronous methods.
Currently have a rock steady 26Usec connection now I have sorted the last outstanding issue with the audio data transmission, and can select any current output digital interface AES/SPDIF/BNC/TOSLINK/AT&T/I2s though I would only recommend this for internal data routing under 150mm.
The system runs at 11.4w and between 0.5-1% processing power WITHOUT audio optimiser which I find is too much of a compromise at the level I am running at.
Every PC is different and in various states of set up and therefore different results will be generated by different people. So AO may give you great results in your system.
The possibility of a mini atx board dedicated to audio maybe closer than you think, I know of at least two companies in the far east who are in beta test mode currently.
That said, with the latest arm processors the Pi is only going to get better and as an open source project is great

Did a new version of my StreamerPlus player today. Now the player puts itself to highest Windows priority class. On a fast Windows 8.1 machine it goes to "realtime priority". On older Windows 7 to "high priority" which is second highest. StreamerPlus downloadIf anyone is interested I can start a new thread on this player? Did some testing today: Upsampling to 96k sounds good. Upsampling done from Control Panel / Audio / Advanced. Put latest versions of dll-libraries to the zip-file. Comparing to JRiver. If I add a little treble from pre-amp, my player sound as good as JRiver. Also JRiver has just a bit more mid emphassis.

Some of the small passsive cooled shuttle motherboards could be the right way to go, with a low powered quad-core Atom processor. You'll never find a motherboard without USB these days, but there's no need to install the USB subsystem drivers, or you could uninstall them. Keep things to SATA, ethernet and S/PDIF and you're cooking!

A new thread about your player would be great!

I got my PC to 16gb nice easy install on the PC It taken me a bit of time to figure out what was happening with my drivers in ASIO but finally got Bug Head playing music ( I think this mostly down to the NAD). So sound is in professional mode and the system is hibernating but not using anything else yet. Very clean detailed SQ even in this setting and a step up from my usual set up. Not a hint of harshness and good sense of musical flow. I am using 4.94 I add a link if anyone interested
