where best to spend $2-3000 upgrade dollars in my system

@bksuperphon2  If you are going to explore contact enhancing, I would
suggest checking out the new tweak in the member review section.
The product I am pointing you to is 6x the price. There are users who have tried both. So there is no mistake, I am the manufacture of Total Contact  

@bksuperphon2

Yes, indeed he does:

Price for the 2ml tube, which is way more than enough and has a long shelf life is $25.00 US. Bob, the chief mad scientist is a great guy who has a great product. He's an electronic and software engineer by trade.   Also, he offers a money-back guarantee if you’re not pleased. I am not affiliated in any way except as a happy customer.

Can you identify that which you are unsatisfied with? If so please let us know so that the collective can better guide you in your quest.
You have what appears to be a decent system. 
There are many ways to throw money at an audio system. Many are misguided.
Don't try and fix something that isn't broken.  

I agree with Jadedavid, if its not broke dont FIX it! BUT this mixy patchwork of cables you have all sound different! If it were me, I would try and get some synergy going by changing cables to mainly one brand. You seem to like Kimber (neutral sounding good lows and mids and highs), why not start there by changing everything to Kimber (solid core copper)...12TC for speakers and Kimber Silver IC’s. I find Monster (tiny multi stranded copper) and Cardas (various thickness solid core copper) to be very "colored" in MY system, and I think using cables to dial in the sound the way you want is the perfect way to go. Listen to different cables,most have return polices so it shouldnt be a costly matter. I have also heard great things about Anti cables, Morrow Audio cables, Signal Cable, The cable company.

P.S. I am also a big opponent of the use of power conditioners.....they color the sound as well.
