Leif, Once again you succinctly answer all the questions posed to you with an open mind and an eye towards the future. I am a small fish here in a big big pond. But, from what little I know and have learned I would suspect that not having +48V phantom would be a drawback and play against the unit. There are some mics which require a certain lower voltage but I am not well versed enough to be able to cite which mic and what that voltage is, maybe ribbon or tube mics? Maybe someone who knows will chime in. As for power the "norm" for a lot of guys running portable rigs is 6V, 9V & 12V. They also seem to be the most supported voltages by aftermarket manufacturers. Remember that I am a novice and you are the expert, but if I were to be looking at a portable design, I would try to base the external battery requirement around those voltages or multiples of them. I keep saying external because of two reasons. One it cuts down on space and two it lets the user choose the battery life that best fits their needs. As for would anyone buy these, besides the live record people I would expect the ENG and film market to be interested in any high quality portable gear. Thank you again for your gracious replies. I would really like to run some of your gear one of these days...do you need a distributor on the West coast of the United States? It's really great that you take time out of your day to stop by hear and let us pick your brain and field our questions, it's refreshing to see another person who makes equipment taking time to talk to the little guys. Take care, Kirk
