I know it is a old thread, but just thought of giving my 2 cents on the f1 fractals. They are one wonderful ICs. I have tried Wywires diamond, Shunyata Alpha, TQ black diamond, AQ earth and Shunyata anaconda ztron. Everyone of above their strengths, not trying to undermine them, but f1 fractals does everything better. It really gave me a "wow" moment. There is nothing like "night and day" difference, among the above, but if I had to choose one, f1 fractals will be the one. I was considering to try TQ silver diamonds and other higher priced (> 3-4 K), but I might just stick with f1 fractals. The more I listen, the more I feel like I need to keep them and stop searching more.
