Okay so being budget minded first off tweaks like these are way more cost effective than component upgrades. Then trying to squeeze the most out of the tweaks... ECT and all the HFT versions are really very comparable. Also it really doesn't matter what you've done, they'll work just as much magic regardless. So what I would do is call and talk to Betty at highend-electronics.com and tell her just what you said, looking to get more Synergistic magic but gradually in a way that makes sense.
What you're looking for, they have done specials on Synergistic and may be doing some again. Try and find out. They've done things like buy two get one free, buy one thing get another. That's how I got my Blue fuses, they were a freebie with ECT or HFT, and the darn Blue fuse was so good I kept buying more HFT just to get the fuse!
Now Orange is the new Blue but you get the idea. Can't go wrong with any of those, they are all very good value for money. But if you can get one free with the other that is definitely the way to go. So call and ask. Never hurts to ask.
