So, I have the itch to upgrade my K702 headphones to something... better. I love listening to female vocals mainly but also occasionally reggae, jazz... a wide range really.
My main question is, would my setup (mainly, headphone amplifier) be suitable for powering the HE-500's? The HA540 has a max output of "up to 500 mW/side, 1 W/Stereo ( @ 16 Ohms )". (http://www.rolls.com/pdf/DS_HA540.pdf)
My current setup is: Macbook Air > HRT MS HD > Rolls Bellari HA540 > K702.
Thank you for all your input,
