Need some suggestions for a desktop amp.

I'm in need of some ideas/suggestions for a desktop amp. built in DAC would be a plus but not necessary. I used to have a Naim Untitqute driving my Harbeth P3ESR's which are very nearfield. My issue with the Naim is the large form factor which takes up a lot of space on my desk. Although the sound and functionality was great with the built in DAC and all.

The issue is, most amps with a smaller form factor made for desks are Headphone amps and not speaker amps. 

I tried a little Chinese amp but the ChiFi amp I ordered wouldn't work hooked up via USB to my iMac like it was adverstied to. So back it went.

I considered buying some Active Speakers but have never had any experience with them so not sure what direction to go. I love my little Harbeths so would like to keep them but I'm open to making a change if need be.

I'm close to pulling the trigger on a Nuprime IDA-8. However, I wanted to get others opinions first.

Thank you for your thoughts.
