Hi Maghister - I’d never call you or anyone ‘nuts’ !  And I’ve always included myself and indeed all of us as persons vulnerable to placebo and confirmation bias.  And I am totally with you when it comes to experimentation, especially the affordable type!

At least you acknowledge the existence and role of confirmation bias. I’ve enjoyed hearing your experiments.  What is a red rag for me is when some posters here either refuse to accept these phemonema exist, or refuse to accept they are vulnerable to them. 
Over and again we have “I turned my fuse around to improve my sound and I’m sure it improved my sound. Therefore turning a fuse around makes systems sound better. And you can’t deny it because I trust my ears!”

We all of us should acknowledge our confirmation/optimism bias as a factor in tweaking, or produce some evidence which is free of that bias, before suggesting folks should part with their hard-earned money.

Hi Maghister - I’d never call you or anyone ‘nuts’ !

I apologize to you for answering some other post in my answer to you...You are respectful and i thank you for that...

At least you acknowledge the existence and role of confirmation bias.

it is IMPOSSIBLE and pure ignorance to contest the placebo effect or bias impact on perceptions... It is and always was evident for me and i always think it must evident for all...

BUT attributing all my final results to bias or placebos by principle and about anything called "tweaks" by principle is for me deceptive and unfaithful to the experiments like denying bias and placebo effect also are...Separating placebo effects from the real impact or not of any device is the crux of the audio experiment...

I will repeat myself, placebo or not, i bought nothing except peanuts costs devices, i created and modified most myself and replicated with homemade materials mostly from inspirational branded costly devices...

My results are there in the form of my ONLY advice:

Dont buy anything new ever BEFORE embedding what you had already in the rightfull manner....

It is not consumerism advice all over the place not "snake oil" marketing here with me....

It is a learning process in the 3 working dimensions of any audio system: mechanical, electrical and acoustical...

It is not the magical "tweak" in itself that interest me, it is the way and method to reach an optimal experience, never mind the specific gear...My way is learning through a set of listenings experiments with low cost artefact and means...

Audiophile hearing is a learning habit experiments in a KNOWN room and with KNOWN gear, not an innate infaillible gift usable everywhere with any system like suggested by some ....

@audio2design, nobody likes being the fool. 

@cd318, that dark side has always existed but science has also been de-legitimized by marketers making false claims under the guise of science. "Dr George Peebrain PhD in aquatic afterlife discovers that jellyfish pixie dust cures Alzheimer's disease." 
Real science really works. You hold it in your hand right now. 25 years ago that thing was the size of your average brief case and only did one thing. Make phone calls and it was not all that good at it. I just recently downloaded a seismometer app. I can put the phone down on any surface, tap or bang around and see if it registers on the phone. How cool is that?

Mahgister - you are not nuts. Like you say, you are conducting experiments in a lab type environment. You are not imposing a lab look into your living area like Chuck McGill on Better Call Saul. Sounds like you are having fun which is what this hobby is all about. I like hearing about your experiments.

It consumed Chuck's life and literally drove him nuts.

Double blind tests eliminate any bias, so long as they are conducted properly, which is not easy. Warm up times, adding or removing (or not changing) the variable, playing the passage exactly the same way, having the moderator not inadvertantly disclosing cues at whether or not they did anything, etc. An offhand comment about something sounding muddy when a speaker was moved off a cable elevator does not cut it.

If something does not have a logical description of how or why it works, then we should be skeptical. If something does, then it is up to the individual to determine the effect on the sound and if any, if it is worth the expenditure. 

The easier it is to understand the logical description by someone with a basic understanding of science and the scientific method, the greater the probability that it is worth consideration. People who dismiss double blind testing obviously do not have that and can't imagine an experiment on how to measure gravity's effect on falling objects for example, they just beleive it. Do they even know that the force due to gravity changes on the moon? Do they even care?

Thanks for your kind words...

For sure my goal was not an experiment...It was reaching satisfaction with my gear... With no money i never even know that it could be possible... The first steps begins by accident but in the journey i begin to understand what matters and why...

This is what i called the working controls in the 3 working embedding dimensions of any system...

Then the universal advice to upgrade begins to reveal to me his ugly face: an illusion half the time ....

Because it is more important to tune the gear at his right level of optimal working than buying new one....

Simple...

Who say that loudly?

I am not interested either by buying " tweaks" they are most of the times too costly and none of them solve by itself the problems in all 3 working embeddings dimensions... In the opposite the sum of all my low cost devices did it to a great extent all together...

Then i am anything save "nuts".... My audio dedicated room is "crazy" but it is NOT a reason to dismiss my conclusions....

The control over a free room for my experiment was my only real advantage over most people....My gear is good but average....

My sound is not average at all tough at the end... It is the best sound this average system could deliver and it is way more than what we think possible... It is the reason why i could affirm with confidence that most owner dont know what the gear  they already own is able to deliver in the right conditions....
