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

So I have a pair of Mirage M1 speakers, I changed the caps in the crossovers to Jantzen Superior Z (for the tweeters) and standard z for the mids and bass.
 
I also changed the internal cabling to Supra Classic 2.5.

First Impressions-  Not burned in yet
The highs are there but really recessed in the background. Theres a song I reference and it has a steel guitar solo, I can bearly hear it through the vocals because its seems recessed so far back.

SO HERES THE QUESTION- Is that a symptom of unburned in cables and or caps, or is that just what Supra cables give you?

When I changed the internal cabling a few years back on the same model speaker, I used DH LABS t14 Silver plated cable, This had the opposite effect, it was super bright and fast, but it smoothed out and the brightness relaxed, leaving a lot of detail but not so much your ears bled.

But here its the opposite, its dull on the top end and the vocals kind of take over and blur out the top end.

So this morning I was fortunate to speak with a guy from a Mirage distributor who was quite familar with the M1. He said that the ESR should not be an issue.  He told me to check all the solder joints. So I did and I realized that the joint feeding the "hi" section of the cross over looked suspect I re soldered it and tried the crossover, and low and behold the upper highs have returned to at least be in acceptable parameters, and comparable to the other crossover. 

Despite the tweeters sounding more normal, the sound overall still sounds a smeary, or, maybe choppy, I dont know how to explain it, its not quite smooth yet.
So will the smoothness come with time?  Tim did you find this with yours?

Another thing is I am wondering if I should increase the resistance due to the lower esr caps replacing the old Electrolytics. I dont want to get to far off from the traditional M1 Sound, but I am up to increase the detail and smoothness, which is why I replaced the old caps in the first place.

Enclosed is a schematic, if it may help.

What are your thoughts, leave it or add an additional .5 - 1 ohm resistor.

Or if I should just burn it in and if the sound is good, leave it as it is..,,...

Thanks for posting the schematic Sean.... I can see a lot more now.... OK, so this is a series crossover,  parts burn in takes about twice as long to burn in rather than a paralleled layout....  Yes,  I had a similar effect on my speakers and no,  I would not change any resistors. 
My instincts are that your ears will take some time to adjust even after these break in.  The Z is a tad more laid back than most, yet a very detailed pleasing cap.  I suspect once they break in fully and you become accustomed to them,  you won't want anything else.

So looking at the schematic, the two caps I would be most suspect of are C3 and C4. Note they have a resistor in series with them, so the overall resistance there must be important. I would suggest you go back to the original caps there, and listen again.

If this fixes your problem, you’ll want to figure out the ESR of each one by substituting larger R3/R4 to make up the differences.

Almost missed it, C1 is the same way. My suspicion is that the resistors in series are going to be really small , like 2-5 Ohms max. 

Best,
