Any tweaks I'm missing?

And MG, thanks. I will end up pulling things out, to find what works best

. You were told to remove it yesterday, by others not just by me, and dismissed them also.

I’ve had pocket money to experiment as I have, after reasonable advice from others

Not even reasonable advice, as it’s cost you serious money, which would have been better served in a reasonable equipment upgrade instead.

I have tried a number of the same tweaks as you and found them beneficial. But the biggest impacts I have had are from the PPT Omega mats (treating the gear), and Synergistic Research products treating the room. So great and profound have been the changes that these "tweaks" have wrought that I would call the "tweaks" components in their own right. Sure the "system" functions without them, but it functions better with them. A lot better. A helluva lot better.  My system with "tweaks" (ie the added components) performs better than any system I have ever heard in a retail store regardless of cost. I couldn't say that before I started "tweaking".
Looking at your list I see lots of treatment of your gear, but not much treating your room. I would suggest that is the next frontier for your pocket money. Investigate HFTs and FEQs, you won't be disappointed.

Wondering about this Akiko Fuse Box Tuning Chip, it claims to permanently  apply "Harmonising Energy"  to the entire power supply in the house. What exactly is "Harmonising Energy"? Does it affect anything else in the house? Hair dryer? Microwave? Make better coffee? 

My guess, it’s like WA Quantum Chips. Somebody figured out how to harness the power of artificial atoms. All you have to do is calculate the specific resonant frequency or energy of whatever it is you’re trying to affect. You know, like the Intelligent Chip that aimed to affect the resonant frequency of polycarbonate and make it more transparent. It’s not rocket 🚀 science. Well, maybe it is.

Thanks Michael Green for wise words and advices....
It is a pleasure to read your opinions.

I just want to say to some that my homemade tweaks cannot be snake oil because I create them myself at the cheapest cost...And after the creation of these homemade tweaks I can listen to ANY and all and EACH one of my cd files with musical enthusiasm...Without these tweaks I would be in the necessity to buy costly upgrade , and be in a constant state of unsatisfaction like I was upgrading…...Because it is impossible to makes a speakers sound right without room treatment, tuning, or cleaning the house noise level for example, and without controlling the vibration resonances phenomenon...(Samething for any piece of electronic gear but more evident with speakers by the way)


Then speaking about upgrading electronics is at least half of the times be influenced by marketing engineering and more than that throwing his money to the wind, it is paying too much, more of the times... An audio system, a mass of electronics if you wanted, exist at his own true OPTIMAL potential capabilities ONLY in the controlled embeddings of a room and of a house, and of the audio grid, call these necessary means of controls  : "tweaks", tuning, controls, treatment, cleaning, or " snake oil", that’s is the way it is and it must be, except for non-thinking mind...No controls-cleaning-tuning-tweaks etc , equals no optimal sound, for most of us most of the times... The exception is the 100,000 dollars system with dedicated room treatment included and even that, I does not like necessarily all of them sonically speaking...It is always better to makes that happen one step at a time for our own ears by ourself... 

Before the installation of my "tweaking" methods many of my files sounded way less listenable, the lived concert for example... Now I prefer lived concert because my stereo system gives me the exact atmosphere of the site where they recorded the piece...

My best to all and to you in particular...
