Ok, perhaps your definition of 'accuracy' is different to mine, ie I prefer Two Flames loopback recording because I find the clarity, dynamics, focussing and stability to be better than the 'Test Dept' original.

I agree on the subjective quality of the Two Flames. But I predict that it will ruin timbral accuracy of normal music. You know, musicians pay great attention to timing etc when playing their instruments. It is what separates good musicians from bad ones. You want to hear why a great musician is great regardless of recording quality. That kind of accuracy. (So next time, choose music from some legends).

I meant CD, tell me a title or performers and I might be able to find it.

It was local CDs, not something you can find globally. I have been years not listening to CDs so haven't seen them around hehe...

BTW, the analogy of Test Dept to Two Flames is like Solen MKP to ERO MKT (as input coupling cap) 🙂

Basically, there is more than a small amount of misuse of the term 'expectation bias' at places like that other audio website out there than features a lot of measurements. They say it means you hear what you expect to hear, as though the claim is some kind of proper scientific explanation for how people hear, which it is not. There is no published research I am aware of in cognitive science which defines the term expectation bias in that way. If there is such research, I would appreciate someone pointing it out.

OK, you have lost me in pedantry. I have no idea what I will hear in Dan’s files, but I will put off listening until tomorrow, as today you are having a negatively intrusive effect upon my finer sensibilities.

Try finding a 'healing spot' or 'sacred spot' and take a listen to nature sounds then move off the spot and you will find sounds are different, what JB is doing is messing with fields, you have much to learn Grasshopper.
Well, I have never been called a grasshopper before. Is that a compliment or an insult?

The rest is alchemy masquerading as physics.
 
I'm not sure it is pedantry. If we are going to bandy about terms we should at least use the right terms? Question still is, what is the right term? Confirmation bias is the closest I can find, but I'm not convinced. Congruence bias also seems to apply to Dan as does Conservatism.

OK Bill, I will go along with that.

It’s actually quite difficult to form a consensus of understanding here ....... sometimes. :headbash:

I found that wearing my glasses upside down while on my back under a recording console was very useful for that type of activity.

Wearing variluxes for may years.

Hi Alan,
Tried that but then had to fish out my glasses from the inside of a washing machine with zero vision 😀

It's impossible. We can't even agree on simple terms like 'dynamics' or 'soundstage'. But we can't give up or madness will ensue.
 
Well that’s a lot to go over......at least it seems semi civil so far, I’ve been working long days and wife is leaving for NC in the morning.

I’ll hit those tracks up in the morning dan sorry I haven’t had time today.

But it would definately be interesting to have the same tracks available for all to analyze and discuss both objectively and subjectively.
 
Yes, very hard to judge what is the cause of the rather small increase in the 0dBFS plot. <snip>
I think I have stumbled into this as well, a while ago. I have observed this high frequency hash modulating the noise floor on the output of the AK4490 while I was looking for differences between PCM / DSD drive.

It got less pronounced in the DSD (256) drive mode. https://www.diyaudio.com/forums/ven...4490-usb-dac-dsd-support-149.html#post5287570

Could be connected to the multibit modulation scheme?

Ciao, George
