I understand why you like to play with the gear...😊
Myself i am not someone who like to play with things at all ... I am more of a books worm...
But i get in the obligation to learn about acoustics because i was going nowhere buying audio gear...😁
My 9 headphnes where trash...😁 even after my improving modifications they do not satisfied me ( save the AKG K340 the best headphone ever created probably but even it need my help 😊 )
I disliked even My Tannoy dual gold concentric...Because during the 40 years i owned them i was ignorant of acoustics science basics ... 😁
After reading acoustics books and articles i felt compelled to experiment... I do it full time 2 years because i was retired and i disliked my audio system , nevermind the upgrades... Things improved a lot when i discovered how to decrease vibrations/reasonance, how to shield my gear from the main panel up, when i played with various minerals to use on my connectors, when i experimented with Helmholtz tuned resonators in a specific grid distributed in the room and the right balance of reflection-absorption-diffusion in my room. i used other controversial devices as shumann generator i modified , at the end the same system was so transformed that they were no comparison between before and after...
Unlike most people who dream only to buy new gear pieces, i learned how acoustic knowledge improve the gear way much than most upgrades , the only exception will be to go from cheap speakers to way more refine one , but even this upgrade will not compare if you put these speakers in a living room and then in a room dedicated to the speakers specific properties... Acoustic rules for me the rest is marketting mostly ... 😊
Now i own an headphone able to project the soundfield out of my head with deep bass and natural timbre...
And the cheapest speakers i ever owned which i disliked for 10 years became my best one AFTER my modifications ...Thanks to Helmholtz...
Then i became a book worm anew, no need to tinker anymore and i can listen music 5 hours a day in sonic heaven ... 😊
@mahgister , You found it! I was mostly just joshing/joking with you on my earlier post. It came in today btw. On these type of cheap chifi speakers, I usually add bracing, put some no-rez (sold by GR) and I will spend a considerable amt of time with the crossover. I have a stock of the good parts GR sells. That’s the extent of it for me, typically.
I have tinkered with many similar cheap speakers, amp kits, etc from AliExpress, e-bay, etc. After it meets my fidelity requirements and I don’t feel like dealing with it anymore, I give it away on FB, artist groups, etc ( possibly creates a few new/young ’audiophiles’ or not....but, keeps the audio stuff cluster in my hoarder’s paradise under control).
The Sony (sscs5) was one i couldn’t let go of in recent times, especially after I put the GR upgrade on it...that one’s staying for a bit.
It seems like you would enjoy some of the content in the diy audio forums.
