Being a pro and being able to spot about some problem in a system/room when looking at it , does not means that anybody can judge the S.Q. of a system from a photo...
The reason is simple : acoustic treatment and control are not ALWAYS predictible by visible cues...empty tubes of different kind, one hundred perhaps, of different size are not pretty to look at...it is the "bones"of my mechanical equalizer" though...
For example the number of acoustic devices and their precise size and location is not something COMPLETELY visually meaningful... It is related in a specific way in its tuning to some specific gear for some specific ears...
Then the fact that a pro can point to a room problem on an image is one thing but the final S.Q. result must be LISTENED TO...
Sorry...
Then if someone look to my silly room photo , in no way he can affirm that my S.Q. is pure shit because my room look silly... And it is silly room , my room is a laboratory made with discarded materials then at no cost......
Audio is not guess based on price tag, and image...
For sure some audiophile whose acoustic big room are created by pro at high cost and esthetically beautiful scream a S.Q. quality from image that will make my SMALL laboratory room pure junkyard sound...
But my room is not pure shit in S.Q... Sorry.... Appearance can help : Mike Lavigne room scream high quality sound from photo... That does not mean that my silly mad scientist room is shit even compared to him ...Way less good for sure but not shit...
How do i know? Simple because i enjoy quality music filling my room with a relatively natural timbre ... And my ratio S.Q. /price beat Mike Lavigne big.... My system value is 500 bucks... Beat me naysayers who look at photo to judge me...
Just an exemple now to indicate how it is easy to be wrong:
I used reflective metal junk device who will be judge to have "negative" effect by any pro...This is not untrue...But this is not right too...
how could they be wrong?
Because i tuned my room using some % of reflective surface from certain spot that are meaningless if you dont listen the room tuning process at the end and only look at cheap empty aluminium cauldron linked together...
I dont recommend people to use cheap cauldron to tune a room, i recommend them to use some reflective surface for positive effect in the tuning process...Do you undersatand the difference...I had ZERO budget to achieve my goal and i am very proud of that...
