This is simply not the case. Your implication is that some are in denial about this. Your "special" PC will not solve the problem of USB packet jitter, it will not stop rf coming out of the PC.
More to the point, joe ordinary will have no idea if or how much the problem has been addressed, indeed if it even has, by building their "special" PC. How has tony identified that he has cleaned up these issues? I thought john had only just identified and measured them?
There was a time when jitter in spdif was a significant issue, however once identified solutions were designed. It isn't a generally problem these days and can be measured and quantified.......except if you are Acoustic Research of course .
I picked this post to quote but I could choose any of them as you just keep repeating the same thing. Nothing to see here no point in trying/making improvements etc etc.
We know your position and as I have said my experience and plenty of others totally contradictions your subjective view on improving transports. We have established that you are entitled to your view and I accept you have that viewpoint but this is an open forum where JohnW seems to have access to good measurement tools and has identified something he can work on. Asking him to consider either expanding that testing by trying an optimized PC or at least think about it or investigating if he knows somebody locally who could bring one to him is worthwhile imho.
I am delighted JohnW has seen the light on USB issues and just hoping he keeps digging.
To answer your question on how I did it. I didn't do it I listened to a variety of people and collaborated where possible to test/trial a variety of components. I ended up with a linear power supply (3.3v 5v,12v) into regulators and on into lifepo4 batteries. No pico on the motherboard and luckily a friend was able to replace 2 mobo clocks and they are powered directly rather than thru the mobo. Operating system is on ram(Ramdisk). No internal hard drive when pc is running. Just Win2012R2 running in ram. Optimized operating system(approx 30 tasks running) and external LS powered HDD. MQn minimal player that loads music into ram. Others have gone a lot further or have bypassed the battery route and gone for better quality power supplies. BTW initially I started and still use in a second system a maplin linear supply thru 12v motorcycle battery into pico on mobo. Operating system on USB and that is realistically priced and achievable and is well ahead of a laptop. (IMHO to close off any attacks)
BTW it is not lost on me that if John Kenny,Mark from Item or myriad others suggested something like a Detox it would ala Cantona bring the seagulls round to circle the pirate ship. Sure to finish off I will give you one of your knowing winks
