What is wrong with op-amps?

I'm talking about some kind of deeper (quantum ?) effect.
I have used two different USB cables to transfer two copies of the same wave file to flash memory storage/player devices.
Playback A and playback B sound different, and further ABAB is different to AABB.
During first play of A the system changes and takes a 'set' coinciding with the first high momentary peak level somewhere in the passage.
Upon subsequent playing of B, the system retains A signature until the first high momentary peak level occurs, the system then takes B 'set' and subsequent plays of B reveal no more changes.
Replay of A file will reset the system back to the A 'set'.

Change of source equipment will change downstream system in same manner.
Change of interconnects will cause same nature of change, although less magnitude.
Extended 'burn in' is a nonsense, all that is required is a system momentary peak amplitude greater than normal operating level.

Dan, do you use Foobar for this, what?
 
Two copies of the same audio file will have the same data bits, but stored in different physical locations. They may have some metadata the same, and some (e.g. date/time) may be different. Any competent playout mechanism should produce the same voltage signal from these two different but identical files; same voltage means, among other things, same peak voltages too. If it does not, then there is no need to invoke mystical (e.g. "quantum") causes; simple hardware and software errors suffice. This assumes, of course, that the listening tests were sufficiently well-controlled that they are capable of producing meaningful results.

Mostly Android phone used as a player driving OTG conected dac.
Playing HD stored or thumb drive stored pairs of files via Foobar does same.
Last weekend I played the Android phone into my Dad's large scale soffit mount type studio monitors (Landmark LSX monitors as used in Sony Mastering Studio, Sydney).
His comments were cleaner, clearer, better dynamic range and more musical, same conclusions as me.
I also applied my filters to a pub PA system NYE, same result, sound guys love it, makes their job easier, makes them look good lol.

'mighty' as in strong and powerful. Mighty Thor, mighty mouse, mighty ability that us mere mortals do not possess.

That's a very interesting (and recent) study. I hope somewhere it is being replicated to see if it holds.

The auditory illusion fascinates me not least becuase, if you have something wrong in setup you can hear two speakers as distinct sources. But when things are setup well you cannot easily determine the source, even when you can see the speakers. With the right material you also get depth as long as you stay fairly still which is even freakier.

BUT there is still conditioning. If you have a pair of minimonitors in front of you you might think 'these will image great' whereas a pair of 3-ways you might think ' not chance'. But if you can ignore that conditioning and heresay then I agree completely.

In about 1974 as it happens KEF made a range of speakers that could work as Michael suggested and at low cost. The then Coda being ideal ( poormans LS3/5A ). £59 a pair which even then was no money. A debate at the time said the Hafler decoder worked far better than it looked it should. I always found it very interesting with LP's. Somehow the passive Hafler set up places the noises somewhere other than where I listened ( headphones in my head ). The similar digital trick via Yamaha DSP was similar in style except the noise was with me. That seems easy to explain now, it was a big surprise to me. The speakers we used for the experiment were Mission 760. They were good enough to do the job. It was the least fatiguing sound I can remember apart from Quad ESL. NAD 3020 used at first. The DSP was fatiguing. First listening said brighter. It is said old SQ or QS comes through Hafler showing some of the intended traits. CD4 by JVC gave us most of the treasures of modern vinyl. Not least the ability to work well above 20 kHz. JVC X1 being a star of it's time.

PS - Is there anybody in the audio world you have not met ?.

Why do you assume that it is only the system that changes, especially given what you said earlier about ears?
 
Cool, reads like cable burn in stuff.

Burned in a few cables myself. There was the Teflon insulated wire connecting to an ion chamber very close to a neutron source (a few kilowatts of 45 mev protons on a beryllium target for many hours). When I opened the box, the Teflon had turned to powder and much had fallen off. A bit was still clinging to the copper wire. Unfortunately, I couldn't connect it up to my stereo to see how it sounded because it was confiscated by the radiation safety officer. But, I'm sure it would have sounded totally rad!
 
Evidently there is more than one SRT, I was referring to this kind -
Introduction to Clarus SRT (Sympathetic Resonance Technology)
QLink
Yes, what is written sounds like hocus pocus, and the pendant products definitely so.
My experiments are with an actively powered totally different approach causing aches, pains, headaches etc to be gone in minutes.
What is your method Bruce ?.

Pretty distant from mainstream science and engineering.

What you are talking about seems pretty easy to test. Go down to the local cancer ward where people are in severe agonizing pain. If it works on them, you may be onto something.

however, if it only works on yourself and people who know you and like you, it may not be such a new thing after all, once one digs down to find out exactly how it works.

It's sad and unfortunate that folks fall into a situation that they can't win. The fact that there are those that want to prey on it is disgusting.

There are also some who genuinely believe their pseudo-scientific claims. It's just a topic that borders on inappropriate for this forum. Not all alternative medicine claims come from psychopaths and sociopaths. I could tell you stories, but not here.
