Earlier this year I purchased a modded older EC 1800. The mod had replaced the"daisy chain" wiring with military spec direct wiring and a Furutech NCF IEC inlet and Furutech NCF duplex outlets. There was a definite positive difference than the EC 1200 that it replaced but not really anything big. Tim Mrock at Perfect Path Technologies offered to coat much of the interior of my newly acquired EC 1800 with a new coating that he has come up with that greatly counteracts EMI/RF interference. So I gave it a shot and sent him the unit. All I can say is within 7 days of his applying the coating to the unit and upon inserting the 1800 in my system the sound had very noticeably improved. More so than the difference between the EC 1200 and modded 1800 and at a lot less than the difference in cost of the 1800 and the 1200..... but it gets much better. It keeps improving. Now at 58 days since Tim's work, the effects to my system is nothing short of stunning. Just extremely coherent, balanced and organic sounding. I am shocked at what a red book CD can sound like! I dont think Tim Mrock of Perfect Path Technologies advertises this but I believe he can do this process with many different power conditioners. This is so easily the best bang for the buck I have ever spent in audio. It is as if I upgraded every component in my system and cable in my system by a couple of notches. I can't tell you how happy I am that I did this. I can't begin to equate what I would have had to spend on multiple upgraded components and cables to attain this level of performance!
