Most of you have no idea how compute or networks actually work. Also most of you are too chicken shit to do this blind.

That’s not contributing to anyone’s enjoyment of this hobby or any other hobby for that matter.

Ok. But is it any the less true? I just offered to come out of pocket and ship a computer to someone where we can vary the CPU load. You figure if it was 2.5 years of experimentation what's another week?

I don’t believe your statements are true but neither of us have any way of proving it. 
 

If you are here for nefarious reasons, your language fits in perfectly. If you’re here to actually find facts, help people, enjoy the community, increase people’s enjoyment of this hobby, it isn’t coming through very clear.

You either get all or nothing.

I don’t accept that from anyone. 
 

A member suggesting he can act with impunity or he’ll leave, will be shown the door. I don’t care who anyone is or what they can offer, if s/he is abrasive and causes problems for 99% of the community, s/he needs to look elsewhere to cause problems. 
 

You act like fixing a handful of network issues is objective evidence of something other than fixing a handful of network issues. While at the same time having zero knowledge of the thousands of other people without issues who use the same hardware. if your shotgun approach fixes an issue, you draw conclusions and act like those are the solution for everything all the time. It’s like rebooting. Solves a lot of issues but tells us nothing about why something didn’t work for one person and worked for everyone else.

In this specific thread, regardless of instrumented measurements showing no change during various CPU load change, you have nay sayers.

I’ve yet to see objective evidence that all people’s audio systems are unaffected by this.

I understand what you are saying, but if this would be 100% true people would not buy servers like Taiko Audio Extreme or use HQplayer. 

I’m always hesitant to use an “if then” statement involving why people purchase items. People purchase things in every category of consumer goods for many different reasons.

Gotta start somewhere... I can send you the same if you are game. What is so tough about a thought exercise like this?

Totally agree we have to start somewhere. 
 

I like thought exercises. Never a bad thing as long as everyone remains cordial.

Nope. What I'm saying is you can't ask me for my knowledge to fix a handful of network issues for members and then turn around and discount that same knowledge as 'inexperienced'.

 

It's like coming and asking you to perform some photography services, have you take something I took a run at in lightroom, and now have you fix it. And then in some other thread I'm questioning your photography chops.

 

Chris, I'm not a photographer and you're not a systems architecture and network engineer.

I never discount your knowledge when it’s in your wheelhouse. Everyone has a limit to their knowledge. Understanding that limit is key.

Why? As long as everything remained bit-identical, which it did, it should be irrelevant.

 

 

Indeed, I had originally intended to use my USB DAC. But at some point Mans insisted that we needed to capture the digital input to the DAC in real time during the ABX (something I came around to agreeing with). I couldn't figure out a way to do this with the USB DAC I had, so we agreed that we'd use an spdif DAC instead.

 

In retrospect, I wish we hadn't used the DAC we did. But it was the only one I had to hand with an spdif input. If I were to repeat the test today, I'd use my RME ADI-2, and capture its spdif output to ensure everything remained bit-identical.

 

Does this totally negate the test? I don't think so. We proved (to a 99% probability) that bit-identical playback can sound different... which was the aim, after all.

 

 

I later proved that it was the Tascam's auto-start function.

 

 

Where did you get 150ms from?

 

 

This had no bearing on the ABX whatsoever.

 

Sorry Paul, I think you're throwing around a lot of red herrings. But I do agree that we should have chosen a DAC less susceptible to the effects of jitter.

 

Seems like it could all be duplicated by anyone. That’s kind of how science works.

BTW, where's @March Audio gone?

He was banned for being himself, a perpetual line stepper who couldn’t help but break the rules.
