He can publicly post for all to read the results of the test, his questions about or problems with its methodology, or his attempts to wriggle out of the entire thing—rather than confining whatever discussion there is to private messaging with one user—or face further unceasing and justified scepticism by said readers.
It really bothers me to see the non-technical people sucked into this technical BS who don't know any better.
I just got offered to sell a $2700 vacuum cleaner (after they give you back $1000 for your old vacuum
I just spent way too much time reading that thread on computeraudiophile and my head is close to exploding. I must commit to myself never to step outside of HA again on topics such as this.I can understand non-technical audiophile people getting wrapped up in this stuff. What I find frustrating is that Josef is a software developer and his response to logical statements debunking his theories. He'll present all sorts of theories on why TLB thrashing or using non-cache memory, low latency, etc. from within a user land Windows app can affect the exact time a sample is delivered to a DAC and that this is very important as it will have a direct effect on the jitter. People will explain that the app has no control over this as it's the OS, drivers, and external hardware that control the final delivery rate. Then he'll counter with "of course that's how it works, and indeed it shouldn't matter when the app delivers the data, but... it just sounds better!". Any time he gets called on technical BS he'll just back peddle to the magical audiophile junk. I have to think he is either deluded or is trying to purposely pull a scam. It really bothers me to see the non-technical people sucked into this technical BS who don't know any better. It's one thing when it's about gold plated USB cables but this hits close to home as I've spent the last 20 years of my professional life doing nothing but developing code that produces and delivers digital audio out all sorts of devices.Anyway, rant off, gotta get my blood pressure under control.
This all comes down to an all-time running gag:"You can´t measure these things, you have to listen, it is that obvious you need no DBT, so many people that hear this can´t be wrong!"

I am as certain as I possibly can be that neither Josef not Marcin is a fraudster, since fraudsters are not known for the provision of outstanding service after the money has been paid.
I enlisted the help of a friend, and we did some blind tests together. Nothing scientific, we weren't measuring dbs or noise levels or anything else - we were simply listening to the music (predominantly classical, flac format, 16-bit 44k and 24-bit 96k - which is the best quality output my USB DAC can handle). In 100% of the samples we tested, we always successfully identified the jplay sound, and always found it to be the most appealing.
As someone said recently on a jplay forum:"...but hell, I'd rather just listen to music than spend my time testing."This comment speaks of an attitude to listening that is very different to what seems to prevail here.
I can honestly say that the technical support I have received from both Josef (the author of jplay) and his partner Marcin has, for me, rarely been exceeded, both in terms of responsiveness and quality of response.
It appears to me that most of the participants in this forum have not actually bothered to try jplay out for themselves, something that is relatively easy to do, especially with an earlier version of jplay since the current one now uses a Windows service). It also seems to me that most are writing about audio as something to be scientifically measured - I can hardly find a reference to someone enjoying the actual music they're listening to.
In passing, I would infer from some of your phrasing that you seem to believe that double blind tests aren't scientific, whereas measuring electrical signals is scientific. This is completely false.
Just because I (or anyone else) can't see logically why sample jitter due to CPU utilisation might be a problem doesn't mean that it isn't.
Oh, and sorry to be pedantic, but it's "different from", not "different to".
What you must do now is provide the details of the experimental setup as exactly as you can, and then I'm sure people here will attempt to reproduce your results, or comment on the experiment itself.
I'm sorry you feel that way. I, personally, would much rather listen to music than spend time incessantly tinkering with my audio stack; behaviour that is typical of those audiophiles who claim that every tiny insignificant change is "night and day" or "immediately obvious". Worst case, the fruitless tinkering becomes an expensive hobby, when a fraction of the money can deliver the exact same aural experience and the leftover money can be spent on good music and concerts tickets of your favourite artists.
What kind of technical issues did you have?
