I have used fibre extensively in my system, it does clean up the sound and fibre cables/SFP modules are cheap compared to hi end copper.
Having said this, the biggest uptick for me was thru reclocking - someone mentioned this earlier in this chain.....absolutely right. Using the uptone Regen switch is a cheap and very effective way do do this, with a lot of added benefits. Adding another switch in series gives nearly as big an improvement. I use the top of the line SOTM in series with a Regen.
Totally agree that you can get big upgrades in SQ without equipment upgrades. Critical Mass Systems footers and some Synergistic Research products have to be the biggest single example of this line of thinking. Some of the items are expensive, but mostly cheaper that hi end components for same improvement in SQ.
