Don't bother with castle, he hears with his eyes... literaylly, who cares about if the LO is 0.254v, or who cares about those fancy graphs like FR and so on, impedance match meh!.
Let you ears be your ears and they are your best judges in the panel, they decide which amp or heaphone passes and which Not.
I already love the sound of my A17, is phenomenal, the "concert" sound iwas looking for years after attending classical music concerts and hearing the reality vs on an iPod or even older walkmans, but yeah We want amp to drive our needy cans to their asking level
That doesn't say i will risk the sound of my A17 by plugging it in to an external DAC, but unfortunately i must do so risk a purchase because in emxico there are hardly any shops forhi-end audio so i can't test drive some gear i wnated to
I hear you brother. Don't feel bad, even here in Ottawa there are so many things you can't try before you buy. I guess there is just way too much gear, and so much new gear coming everyday it seems that I can't imagine your normal audio store being able to offer even a modest selection for trial. So nice to hear how much you like the A17, kind of makes me appreciate mine more as well. Can't wait for the PHA 3 to be here, should be very nice.
