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.

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.
The ONE is a true ONE way, point source speaker without a crossover. There is no crossover like NO crossover. The ONE driver is DIRECT coupled to your power amp. Nothing get's more revealing.

Whoah, no offence, but I heard uber-expensive Parasound amps driving KEF flagships in Newport last year and thought it was absolutely unlistenable! Shrieky, bright, fatiguing, horrible! Like a match made in Hell.

If I was doing a desktop system (and putting the speakers on the desk!), I'd just get some active studio monitors like from Focal or Adam.
Weird I have a pair of Sound Field Audio M1 outfitted with the uniq driver from kef and do not find them to be harsh at all. In a nearfield set up they are incredible.
