For me the hobby was neither a mountain of the highest S.Q. to reach at all cost,
neither a Kaleidoscope of upgrades to felt a change because i am not satisfied or i am deluded by new purchase propositions,
for me this hobby was a road to learn how to install what i can afford...
Acoustics learning was the key, experiments and concepts...
Add to this vibration controls and resonance controls in my headphones and gear pieces,
Controls of my house/room electrical noise floor and EMI,
Tweakings with different methods with my homemade experiments ( no purchase of tweaks)
It was a journey on a road towards the threshold of minimal acoustical satisfaction or TMAS, extraccting the most of their potential from my 3 different speakers/rooms and from my headphones...
TMAS is important concept. It means that when you reach this minimum threshold you feel it so well that you had the impression to touch the acoustic goal. There is always more to extract but we must stop somewhere... The only way for me now to go further is buying Dr. Choueri BACCH implementation .
It is done...
My hobby is reading and music...
I learned a lot not from reviewers but with my intense discussions with three audio engineers here (objectivist) by realizing that they underestimated acoustics & psycho-acoustics and over valuated the material technology they used ... Thanks to them i conducted intense research and experiments... One is well know it is Amir...If it was not for his rant i will not had learn so much even in theoretical acoustics, which is the field i am the most interested in ...
