The Leckerton does sound like a great piece of equipment. But for portable use, especially with IEMs, I've found that having tone controls, like those on the Fiio E-17, is invaluable for getting good, balanced, and satisfying sound. I know ultra-purists will say that running the signal through tone controls introduces distortion. Yes, I'm sure it does, but not enough to outweigh the huge advantages of being able to balance sound that might otherwise be very unbalanced. Why don't more companies put this feature on their amps? The Fiio sounds only average as a DAC, but the amp section is not too bad and with a really clean input signal, plus the tone controls, it sounds really great. So I won't be buying a Leckerton any time soon, no matter how good it may be in all other respects.so am still on the search for one that would encompass all three quality,controls,portability;
