What's your budget? and do you want just an amp or a dac/amp combo? HotAudio makes some budget amps that aren't all that small nor all that pretty, but they sound good and have lots of power.
Go with the 32 ohm version unless you want to spend a lot on amping for the heavier ohm versions.
ya my budget is max 250$ including the amp......i am not looking for a amp/DAC combo.Looking at the price of the DT990 and the fact that i would need a good amp means that its too pricey for me. I wish i could afford more but unfortunately its not possible right now. Looking at the other options I like the HD 598, what amp would be best suited for it within my budget?
