The new Alpine PDX line looks incredible on paper. Does anyone knows what technology goes in the amp? There are shop producing digital amp chips, Tripath and Texas Instrument(new). What is in it that makes it so small and efficient. I'm in the market for an amp right now, and I duno if I should wait for these amp to come out in March, because I have a small del sol 2 seater, and would like to get as much out of the elelctrical system as possible, and this looks like a winner in all category (sound, power-efficiency).
