Audience THE ONE on Desktop Need amp


I am considering replacing my Audioengine A2's with the Audience THE ONE for my home office desk. I spend a lot of time working there so I wanted to get better sound.

What amp or integrated would you all recommend for these speakers. I would like to be in the $500 dollar range if possible. I use the Emotiva DAC in this setup and I listen to mostly FLAC's and 320-bit www.MOG.com.

These speakers are supposed to be very revealing so I may consider swapping out the Emotiva DAC for my Benchmark DAC in my main rig. I listen more at my desk.

Thanks in advance.

Well I have made a change to my desktop system and I thought I would follow up.

I decided to go with the KEF LS50 for my desktop to replace my AudioEngine A2's. I was worried that the speakers were too big from my space. A friend of mine was nice enough to come over with his LS50's and demo them for me on my desktop, 57" x 29" (situated in an alcove). They sounded so good that I ended buy going online and buying a pair from A'Gon.

I also bought a Parasound Halo A23 amp from eBay for $540. I already have a Emotiva XDR-1 DAC with digital volume control, $150 on closeout.

The reviews I read online indicated that KEF demos these speakers with the Parasound Halo A23.

So this system is not too expensive for the office where I spend most of my life. In the future when I move to another home I may take these speakers off the desk and put them on stands on front of the desk and a little further apart of the desk. Currently, I am using the KEF recommended foam plugs in the back of the speakers since I am in a tight space.
One additional point for anyone else thinking of going this way. The LS50 are so reveling that I find it hard to listen to 320-bit internet streaming (www.mog.com). With my old A2's mog sounded just fine. My FLAC's sound amazing on the LS50.
