The Gear to drive Mini Maggies

First, I wanted to say hello to everyone. So, I am at a point where I want to start potentially building a nice desktop speaker system. I don't have a listening room and my pc desk is inside my entertainment room which is probably medium to large in size. For mostly near field listening would the following items be overkill or would you recommend something else?

1.) Amp: Bryston 28bsst2 (1 for each speaker).
2.) Preamp: Bryston BP26
3.) DAC: Asus Essence one (already own it for headphones figured I would use the balanced out to the preamplifier if that works).
4.) Power Conditioner: Bryston BIT20 Power Conditioner.
5.) Speakers: 2 Mini Maggies
6.) Sub Woofer: Martin Logan Descent i

Now I admit I am not really good at any of this and it would be my first real audiophile set up for speakers. Do you guys think I missed anything from a sound stand point? I appreciate any help that you can provide.

Thank you,
-Jim
