What is better?

Hello, I recently purchased a pair of JBL lsr305's and some Beyerdynamic DT880's. And I realise that I need an amp and DAC. So, should I get an Audio Interface, something like this: http://www.amazon.co.uk/PreSonus-AudioBox-USB-Recording-System/dp/B00154KSA2 ? 

Or, should I get something like this: http://www.amazon.co.uk/Audioengine-D1-Premium-24-bit-DAC/dp/B0079KWSF4 ?


I don't need microphone inputs as I'm not recording anything.

What is more powerful? What should I get?


Thanks alot. 

which ever one with more numbers

Could you please tell me what numbers I need to look out for? 

oh idk. what are you even comparing?

Please have a look at the links I've posted. I'm comparing "power".

the first one is less expensive and has more knobs.

Please keep the comments constructive mate by not fucking this guy round.

Haha, "Mate". Your such a kiwi
