Mahgister you are totally right that you do not have to spend a fortune to have a brilliant system and you can certainly improve the experience with proper acoustic management. But it is not rocket science and you do not have to spend a fortune doing it either.You already know that even if the hallograph experience interested me for example i NEVER recommend to people to buy costly tweaks at all...Not because they cannot work, to know that, we must experiment, but because they are too costly sometimes for what they give or too easy to replicate at no cost....
I recommend to experiment ourselves...creativity and partaking creativity is my business not selling costly products...
I did it and i dont need to buy anything...
I just dont like when someone attack many satisfied customers because of this purchase with only no sound reason except an alleged kowledge....
For example i created my room tuner after experimenting with the idea behind the "Argent roomlens" product which is sold more than one thousand dollars...
I recreated it in few hours and probably improve it....I recommend to people to experiment with it not to spend money...
All consumerism and all market sells half truths...
The truth is : dont upgrade before knowing what your system can really do, working at his best potential level when it is rightfully embedded in these 3 dimensions: mechanical, electrical and acoustical.... Is it not simple?
Doing that is possible without buying anything costly...
It is my experience.... And i dont pretend to have the best audio system at all.... Just enough good to make for me the idea to upgrade useless....
My best to you ....
