HELP AFTER MY MODS, My tweeters are subdued and weak-

Sean,  I've been reading trying to find why your Tara Labs might be sounding so differently... Still not sure that I ran across it,  but I would rather send you down that path before going through a speaker tear down.  Your cables are solid core, so they naturally will have a roll off on top. From what I've read, they decoupled the cable and added some sort of coupling cap inside of that box...Wire capacitance is well known for how it affects the high end (treble).  As you turn up the wire,  It changes the capacitance to increase the treble within your cable.... These cables appear to be around 25 years old.  What if a connection was broken poor inside of your cable box or if a part was going bad?   Not sure that you can open this thing, but I'd take a look there... Right now,  You've got a lot of cooks in the kitchen, you know how to get ahold of me,  so I'm going to bow out for now,  Tim

I think just for kicks I'll try the other Tara cable, I would think it would be less likely to have both cables have an issue. 

Tim I appreciate your input, not quite sure which way to go aside from keeping music on the speaker. 

The caps I replaced were:
 the electrolytic, (2- 6.8uF , 2- 8uF, a 47uf and a 10uF)
Also film caps, 3- 3.3uF, 2 -10uF and a 4.7uF.
Two polarized electrolytic 2200uF, but these I replaced with electrolytics.

C8=4X3.3uF=13.2uF and you replaced it with 3X3.3uF=9.9uF?

These cables appear to be around 25 years old. What if a connection was broken poor inside of your cable box or if a part was going bad?   Not sure that you can open this thing, but I'd take a look there...

Any outcome?

Imhififan, I only replaced three of the 3.3, and left one existing one in place. 
I tried the other tara cable and the issue was unchanged. I didnt think it was the cables, because although they were old they were in mint shape and I bought them from an old dealer who had them in storage, they were in flawless shape.

I tried Erics theory and replaced the Jantzens in C1, C3, C4 with the old electrolytics. And as Eric suggested the issue had went away. 

So here I am at a crossroads as I have been emailing both Tim and Eric relating to my problem.

 Eric suggests getting an ESR Meter find the difference between the old caps and the new caps and correct it by changing the  resistor (in series with cap) with the corrected value on the resistor.

On the other hand,,,, 
Tim says this is not an ESR issue, he says that the ESR difference is not significant enough cause this issue, and that there must be another reason for the issue, he suggested that perhaps one of the Jantzen caps is defective or mislabeled, or perhaps a solder joint wasnt making a good connection. 
Im pretty sure I've reiterated what I've been told by these guys, if not, I apologize for getting it wrong.

I appreciate the spirited debate and strong opinions, I especially appreciate the civility between everyone who has chimed in.

So thats where Im at, the worst part is Im moving in two weeks and I was hoping to wrap this up before I moved. 

I think what Ill do is buy a tester that can check the value of the caps as well as check the ESR and see what pops out at me. 
Anyone have any better Ideas,,,, dont be shy.
