My Favorite Tweaks, What is yours?

Some of the tweaks posted , Iam not familiar. But I am glad agoners are happy to share what tweaks works for their system.

@zione.  +1 on the smoothlan.  Best $250 I have spent.  Took it out for one hour, had to put it back in.  2nd best are the Magnarisers with with cyro treated jumpers on my Maggie 3.7's.

Isolation springs under the subs and speakers

Electrical noise control in my streaming system

I could never afford the expensive tweeks so I tried the cheap versions and they worked.

• ADD-POWR SORCER-increases dynamic contrasts
• Samsung Evo SSD’s 
• Fidelium speaker cable, eliminated “smear” that I didn’t know I had. Fidelium IC’s, no difference over XLR or Cerious Lumniscate IC’s. 

No tweaks are my favorite...

They are all needed and all worked in their own working dimensions and cannot be replaced by another tweaks from another working dimensions...

Grounding is the most underestimated after acoustics...

Panels  are not enough in my experience of room acoustics...

Vibrations controls is mandatory for sure but the destructive effect vary a lot accordingly to the speakers design and location ( i used 2 set of springs over and under very heavily damp speakers with success at peanuts cost but it is not possible in a living room )

 Some tweaks action is subtle and varied in impact according to the system/room acoustic parameters but necessary if we are able to hear the effect when the room /system is on balance ... Schumann generators located at the right place...

Small speakers vent port hole modification and tweeter directional wave guide modification ( No company will sell you a small speakers with a labyrinth inside or worst outside, i did it myself with success) ...
