Thanks for the kind words Hazza_t10. The cell phone problem might be solved by getting some clamp on (or loop through) ferrite chokes of the right size and placing one on the headphone cable near the plug and the other near the input plug for the E5.
The Mini3 is likely even more prone to cell phone problems because it has no RF filtering on the input at all and it's rather prone to interference problems in general due to the grounding scheme used.
