Using 250ohm headphones with amp and computer 2012-09-05 11:58:35 I have found a reseller for Beyerdynamic DT990 headphones that is selling the 250ohm model for half that of the other models 32ohm and 600ohm. So the 250ohm model is within my financial reach as its $200 US lower than the others. I am also buying an integrated stereo amplifier from NAD electronics in Canada to use the Beyers with primarily. Does anyone know if the standard headphone jacks on amplifiers and receivers will adequately drive or power these? I can buy some AKG's that I know will work but have wanted to try these Beyers for awhile now. I know too that companies like FiiO make affordable (for my budget)desktop amps too that could work with the Beyers.
