If you had to choose 1 to complement the SB2: DAC or Amp

[Sithuk]

I'm planning on getting a SB2 and assembling a headphone rig. I'm looking at the Beyer Dynamic DT990 headphones as they seem to be at a nice price/performance point.

I can afford another £200ish at the moment and would like to know how I should spend it.

The Headroom Micro DAC and Amp seem to be the leading products at this price range (each about £150). Which one should I get?

If I get the DAC I would wire it to the digital out of the SB2 with coax and then plug the headphones to the output of the DAC? I'd adjust the volume with the SB2's volume control?

If I get the amp I run coax to the analogue out of the SB2 and plug the headphones into the amp?

I have a nervous feeling that the DAC will not allow a headphone to plug directly into it....?

I have read about the headphone amp on the SB2 not being that good although the Burr-Brown DAC is rated quite highly. I am also interested in purchasing a speaker rig in the future and could use the DAC for that too.

What should I upgrade i.e. what would you do in my place :-)

Thanks for any advice.
