Someone found the headphone specs to be 35mW per channel into 40 ohm minimum impedance (I don’t know exactly where they got that info, I couldn’t find it on page 39 here: http://download.steinberg.net/downloads_hardware/UR28M/UR28M_documentation /UR28M_OperationManual_en.pdf ). They calculated that means the UR28M should drive my Beyer DT770 250 ohm phones to about 103 dB SPL .
Does anyone here use the UR28M with 250 ohm phones? How do they like the performance?
Thanks -
