I have this DAC/amp ( Grace m903) and I use it to power AKG K 702s. Despite being 62 ohm cans, i need to run he amp at 80% volume to pwer these. It has an output impedance of 1.2 ohms and puts out 1200 mW @ 50 ohms, 240 mW @ 250 ohms and 100 mW @ 600 ohms. I use the balanced TRS outputs for my active monitors ( Neumann KH120s) so I will be using the headphone outputs. as a point of reference I have AKGs for listening around the house and Westone 4Rs for when I travel.
I am considering upgrading my headphones and I am considering a number of the "usual suspects".
Audeze LCD-2 are 60 ohms
Beyerdynamic Tesla T1 are 600 ohms
Denon AH-D7100 are 25 ohms
HiFiman HE-500 are 38 ohms
Sennheiser HD800 are 300 ohms
All of these are well liked are any a better match with my amp? Also, in terms of a jazz listener seeking greater musical detail, soundstage and imaging which would you recommend?
