I plan on purchasing the HD600 soon but have been a little stuck trying to figure out which amp to pair them with. I will be using my ipod with LOD/laptop and apple lossless tracks. I mainly listen to acoustic/rock music and would like the amp to give full sound,good clarity and some bass. I'm looking to spend around $250-300 and would like to keep the size down so i can bring it to different rooms. I was looking at the Maverick A1 or the Ibasso PB1 with the balanced cable or the Ibasso P4.I know the last two are not desktop amps but i have not found too much in my price range for desktops.Please no DIY suggestions. Any thoughts or comments would be great.
