Anybody want a laugh?

Fair enough, if that’s their thing. In my case I haven’t experienced any room issues that I’m aware of, but then I’ve never had speakers with enough low bass that could trigger booming issues so it’s never been a problem.

I dont want to disagree with a gentleman...

I will only say that controls of room acoustics affect not especially the bass frequencies but all the spectrum... And people before experiencing it dont know it and are not conscious of the improper rendition of timbre, imaging and all other characteristis that are affected by the non controlled room acoustic....

I was my self completely flabbergasted by those changes because some people speak about them times to times without insisting on them...The upgrade of a room acoustic exceed easily almost any other upgrade most of the times even of the speakers often...

I wish you the best....

P.S.

Dont be afraid by those who advise to use tech program, or measuring apparus, SPL meter etc... I makes all my changes by way of fun play listening, incrementally, and step by step with the helping of my ears only... There are PASSIVE materials used for the treatment.... But way less known are ACTIVE ways like resonators, Schumann generators, Helmholtz bottles, etc; these active ways changes the look of a room tough much more so than the passive way....My wife dont like that.... But they are very powerful....I use passive and active ways...

I call the acoustical treatment an acoustical embedding of the audio system, there are 2 others embeddings the resonant-mechanical embedding and the electrical grid embedding.... These 3 treatments exceed in S.Q. change any normal upgrade not of one component, but in "some" cases the upgrade of all components, so powerful they are....

Think about any manufacturer in the obligation to reveal these inconvenient truth(for the sale pitch) to you before you bought his 10,000 dollars amplifier or dac? Will you be pleased to learn that day that his perfect engineering gear is not enough by themself to create Hi-Fi experience? Asking the question is answering it.... :)

This is my painful, unsuspected, slowly gained, experience in my journey to win S.Q. Hi-Fi by myselves because of the lack of money...

If i ever had all the money necessary, perhaps i would have never guess that truth and would have been happy with costly gear, almost used like it is out of the box with very few means on controls in these 3 embeddings dimensions.... Like most people if you look at their virtual page system... minimalistic controls if there is some....

The truth is more controls there are, better the sound will be truest to his optimal original design potential.... Most gear are good enough for us if we treat these embeddings... Upgrading is not the way half the times.... And the good news is cost may be low.... I have purchase only very low cost materials and i have reverse engineer many tweaks with ideas of my own and it was fun.... If i can make it ANYBODY can.... I am a poet not a scientist nor a solder handyman, nor very crafty hands man .... :)

I improve the HFT idea with homemade fishing cones lines... And with herkimer diamond inside some.... With various size for the cones.... And even connect grid of cones with copper tape and incredibly that work... I put also a bell of cones in my room center.....

I use also other less efficient resonator and 10 cheap modified Schumann generator with great succeess.... This is ACTIVE acoustic controls...

Most people use only passive materials for acoustic controls, but active methods help a lot especially in the high frequencies...

cost: peanuts

My motto is: Hi-Fi for the poor
My act is: Homemade work

The greatest myth in audio is the relation between quality and price, in fact the relation is non linear....

the second greatest myth is the idea that an audio system sound at his optimal level without needing to be embeds in the mechanical resonant dimension, in the electro-magnetic grid of the house, and in the acoustical fied of the room....

What is a Golden Plate?

Photos and explanation on my virtual system page...

Shungite plate small or big+copper tape on one side = golden plate

This homemade tweak ca be put all along the electrical grid and passively decrease the noise floor for a low cost...

 details on my thead : " Miracles in Audio, by luck, by good choices,by design or by tweaking..."

A linear power supply will be better but will introduce also a noise of his own....

I know i use one....

But add to it a passive materials without electronic components in it, then no noise added, and listen the difference....

My "golden plates" work without active electronic components, are low cost and work better than costlier electronical power conditioner that filtrate but with the introduction of a necessary trade -off....

Unconventional idea are not popular tough..... :)

Please dont propose a blindtest for my golden plates.....i use 30  in my electrical grid....

Good faith is as important than the truth.....Otherwise how can we look for it?

Yes i understand that.... But for me to increase the positive change i must know where and how and what i have done... At the end the change is so great and big, i will take the blind test.... It will be easy to win , but in my house, with my file, otherwise how can i?

To implement the test it will takes a day just to erase all the tweaks...

Another day to make them in place anew...

Oufff All that for what?

Blindtesting a cable is easy .... Blind testing a system less easy....


My point is precidely that: blindtesting a stream of successive incremental changes has no interest at all....The end result is not equal to a change in cable.... :)

It seems it is you that dont get my point without being rude....

Audio does not reduce to what you think it must be ....

Blind testing cannot even " perfectly" prove anything.... But supposing it can, it will disprove a particular change and only one...

The art of audio embeddings imply a successive incremental chain of positive changes.... For that no blind testing is possible except at the end of the cumulative process of changes....I can perfectly remember how awful was the sound of my audio system before and after these 2 years of changes and experiments...The same audio system is day and night....No blind test for me :)

Audiophile must focus on the basic deep problem of audio implementation and improvement not on the defense of singular superficial modification ( like a cable addition) that can be real or not and contest by any blind tester ....

The only way to protect ourselves is experimenting with low cost materials.... This is sufficient to win Hi-Fi anyway if the basic amplifier, dac, speakers are relatively good and well choosen....

Which is why I said before the amp. If the signal over noise and distortion on the analog outputs of the DAC is below human hearing then it’s transparent and all those streamers, switches and routers and whatever upstream doesn’t amount to diddley. Now after the signal hits the speaker and how it interacts with the room is a different story.

Even upstream to the dac all the electrical particular grid of the house, and all that is connected to it will color the sound coming from the dac...The dac itself being a mass of electronic components, so good it is or pricey, will add noise but if rightly design will do it in a good trade-off ... Any small new electronic components, the smaller one also, will intoduce noise of their own.... The audio engineering design is mainly the art of trade-off ...Nothing more...

ALL IS INTERCONNECTED in a non linear way and affect human hearing in way perceptible not only in DB measured way... Imaging for instance is not measured in DB....The instrumental perception of timbre is not reducible to DB measures....

All this is only my opinion and experience, i am a poet perhaps certainly not an engineer.... :)

But i work hard to give to me the Hi-Fi experience at peanuts cost.... I succeed....I succeed with non orthodox homemade improvised systematic experiments and low cost materials, not by buying costly effective products, nor by "buying snake oil"....

The title of my "virtual system page" is: audiophile experience for the poor.....And it is possible.... I did it..... :)

A relatively high audio quality experience is possible for all and cost peanuts....The necessary high price to pay for audio S.Q. is  partly a " myth"....

There is no such thing : a sound without "color"....An uncolored sound means nothing in an absolute sense...

All sound coming from a room, a particular house, a specific electrical grid, a particular audio system is colored in some way for some particular ears that listen to these same" colors" in their particular way and will perceive them in their own way...

Tweaks by themselves are only that: tweaks useful or not....

But controlling the mechanical, electrical and acoustical embeddings amount to more than using a tweak or 2....It need to be take care of in a systematic experimental way.....It is possible, cheap, and audible by me , my dog, and even my wife (perhaps not my wife).... :)

i begins to hears in an indirect way the noise floor of my audio system when i begins to controls the electrical grid of my house and the noise floor of my audio system.... Not before.... :)


A hum or a hiss are only particular noise not giving direct experience of what is the noise floor of the house where is embed the noise floor of the audio system....

Harsh female vocals are explained more by defects in the audio system than by the noise floor level of the house or of the audio system by themselves....

The noise floor cannot be heard by itself.... Only when we modify the electrcal grid and then perceive new details .... Perceiving directly the noise floor level is most of the times not direct perception except in degraded case of a very high level....

i prefer my homemade "golden plates" on my router or on the ethernet connection.... Cost: peanuts, results; success....

:)

In my experience ANYTHING , ANYWHERE, connected in the electrical grid of the house matters to the resulting audible S.Q....

It is what i call the electrical embeddings of an audio system....
