Any benefit- iMac,Firestone DAC, AE5......

would I benefit from adding my Headamp AE2 to my setup?

iMac-Firestone DAC- AudioEngine 5. The AE"s are powered so Im not sure if the inclusion of the AE2 would do much og anything. Should I use it as a pre amp? Is that considered pre-amping?

I'm such a newbie

I asked this in the comp forum but no one answered.

Thanks.

Wow. Not one person can answer this question?
