Mathieu can you post a drawing for me of what you did? Best regards Moray James.

Oh Moray that's a long list....
00 - Change the amps (!) : I'm now using two AW180 from Electrocompaniet. They are a little bit harsh, but high dynamic and enough musical I think. This improved substantially the sound and gave me the envy to go further
1- Change the hi pass caps for 47uF + 0.1 high grade VCaps + the original 15 uF polystyrene Acoustat.
2- Change the 1ohm resistor against 2x 2ohm 10W Duelund carbon graphite resistors
3- Add a 0.01uF/5000V cap in parralel to the high tension ladder (impressive positive effect)
4- Change the four 0.01uF Polyester against 0.02uF 5000V auricap polypropylen caps (impressive positive effect too)
5- I added a step to the tension ladder, but I went back because the sound was a little more 'hard', and I feared to damage the panels.
6- Wash the pannels (one of them, the other will wait)
I've got a list of 'todo' things, including some of the tricks you gave to me. But time is short.
You know pehraps J.Jeanson from Canada. He helped a lot gave me many good advises.
Global result is very impressive, I would say that budget would be about 10-15000Euro to get the same. The weaknesses are still :
- no 'deep' bass (but we are talking about 1+1's)
- the high's are not so 'vaporous' as what gives the good modern systems.
- low power handling in the bass area : when we dance the Zouk, I connect an active filter and 18inche JBL sub, cut-off at about 90hz. This is the biggest weakness of these panels I must say.
... But otherwise, we really play now in the champion's league.
'would look for 2+2 if you have some in your garage...
And what about the mod you proposed ?
