Power DAC or dac+T-amp?

First post in here, hello everyone.

I would like to upgrade a desktop audio in my bedroom (7' X 9'), after i read the posts, i decide to use passive speakers because i can have much more choices.

My budget is around 600USD excluding the speakers, so i am deciding should i buy a power dac like wadia 151 or nuforce DDA-100? I tried nuforce, i think it sounds too polite for me.
Or buy a small dac like halide dac hd, connect to a cheap T-amp likes trends or audioengine N22? (I have tried topping, it sounds too cold)

I am living in Asia so i cannot test halide, and i can only use a small speakers due to space capacity.

My music taste is electronic, indie and pop. But i listen to jazz and classical sometimes too.

Very appreciated if you could give me some advice, cheers.
