I have a outboard dac which also doubles as a headphone amp. Build quality is very good with large toroidal psu plus a discrete output stage capable outputting up to 4.5v...
However the designer has informed me that the output impedance of the headphone out is 50ohm... This seems very high as most seem to aim for as low as possible?
My headphones are 32 ohms (fidelio x1s). Since reading about the 1/8 impedanance matching rule there is a big mismatch here... Ideally I want to keep the amp so am I better off using higher impedance cans which prefer voltage over current (e.g hd650, dt990 pros)?
Thanks
