Aha Ok , thank you for the technical insigth into the touch :) i have no first hand info on my own , so a reatreat in the sceptical corner for now, we wait and see. -- Mnyb -------------------------------------------------------------------- Main hifi: Touch + CIA PS +MeridianG68J MeridianHD621 MeridianG98DH 2 x MeridianDSP5200 MeridianDSP5200HC 2 xMeridianDSP3100 +Rel Stadium 3 sub.
