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

I have the Ohm Sound Cylinders. Nothing like the problematic F's!  Contact John Strohbeen at Ohm in Brooklyn, NY. He can build you a pair in any finish you desire for a reasonable price! I will say this over and over again: these are AMAZING and REVOLUTIONARY speakers! I rate them as good as the German-made MBL's ($60K) for a fraction of the price! They put the musicians right in the room with 3D "holographic" imaging! 

Well as lak and others have stated first start with the AC power.
No matter what equipment changes you do in the future it will always be the foundation.

Here is my order of importance.

1. Dedicated circuits using 10 or 12 gauge wire (I have 3 for Digital, Analog, and subs).

2. Furutech GTX outlets. Don’t cheap out on this important part of the AC power foundation.

3. I really like the Core Tech balanced power conditioners.

4. Quality power cords. I really like the Cerious Matrix.

5. Room treatments, ASC traps, Synergistic HFT’s etc.

6. Interconnects, speaker cables. I really like the Cerious Matrix. (some may be replaced after #7 below.)

7. Then down the line investigate changing equipment.

bksuperphon2,

No, but I have seen the Porter's mentioned many times in the forums though.

To me, getting behind the audio rack to install a outlet is a pain. So, even though the initial cost is more I would rather install the best and be done with it. 

The Furutech outlets can be purchased by many on line audio parts suppliers. The first one to come to mind is VH Audio but there are many. Even on EBay they're available. But caution, the China ones may be knock offs.

ozzy covered it all. I would, however, recommend the Furutech NCF duplex over the GTX (R or G) having tried all of them. It costs a little more but as ozzy said "don't cheap out".
