I've been a little bit worried about the future of our collective future - as a community - with FA. I have never been one for very whacky tube rolling (the maddest thing I've tried is EL3N as drivers) but in a recent exchange with Michal at FA he quite sternly reminded me that EL3N is not within the conditions of the warranty. Which I knew. I assured him that I no longer used them, but have since returned to using EL3N with great success, and want to carry on. I for one acknowledge this is my risk and would be happy to foot the bill in the unlikely (as far as we know so far) case of this practice causing any damage to the amp. But my main point of concern is that too much adventurous tube rolling and too many repair-returns related to it, might make FA more cautious about interacting with the Headfi community as fully as they could, and also make them less likely to come up with similarly wonderful (or better) devices in the future. My concerns might just be rooted in my own paranoia, or might be well founded. The truth usually lies somewhere in between. Not wishing to provoke any debate, but don't mind if I do. I just love the fact that amplification of such quality and character is available at this kind of price. It's a trend I'd like to see continue.
