There seems to be an amazing array of choices with which one can upgrade their stock VMPS speakers.
Given VMPS owners' experiences with upgrades, which ones would you recommend as the MOST IMPORTANT IMPOROVEMENT SONICALLY, in order of importance?
TRT?
FST Tweeter?
Auricap?
etc?.........
Without a doubt it is the new FST tweeter.
If you want a further ranking as far as most sonic improvement it would look like this:
1) FST Tweeter
2) TRT caps
3) Auricaps
4) Solid Silver Wiring Upgrade
5) Sound Coat
6) Delete Toggle
As far as tweaks or after market improvements (in no particular order)
1) Run Jumpers between Binding posts with "toggle up"
2) Slightly tilt cabinet back to aim tweeter to ear level (RM1/RM2/RM40)
3) BiWire/BiAmp
4) Play with Grills OFF!!
5) Add Weight to your SUBWOOFERS to increase mass, and mechanical coupling
6) Add a beard to you 626Rs speaker stand
7) Use both monopoles and dipoles "stacked to make a tripole" for surrounds.
8 Wire/connect your system for an "Analog Two Channel" system first, then HT.
9) Properly converge your speakers (Brian likes a foot or so in front of you, I like directly "on axis") to taste and soundstage.
10) Adjust the putty for best bass
11) Adjust pots for best "balance"
12) Remeber electric power is generally "cleaner" after 6:00 PM, which means better, cleaner sound
13) This is improved if you shut off "all" un-nessessary electrical drain including lights, and other components.
14) listening in the dark or low light is "magic"
15) Learn where the "exact" sweet spot is and how to find it everytime
16) Do Not wear glasses when seriously listening (yes I'm serious)
17) Yawn to clear the Eustacian tubes and equalize inner ear pressure for better highs
18 Also listening with your head tilted slightly forward and down (as in looking at the floor will result in hearing an extended "high end"
19) Massage your external ear to improve blood flow and stiffness
20) I'm kidding about the last one

Gotcha
Anyhow I could tell you all my secrets, but then I'd have to kill you
