I'm using a pair of Neat Acoustics Iotas + REL T/zero MKIII subwoofer in my desktop system. I had Audioengine A2+ before, but they can't compete with the Neats. You can find used ones listed very often. Mine are currently driven by Rega Elicit-R, iFi Audio Pro iDSD Signature and Dynamique Audio speaker/interconnect cables. You do not need all the power from the Rega since your will be doing near field listening and will not even use the first watt of the amplifier. The Neat have a wonderful clean sound and being positioned a couple of inches to the front and sides of my 23in monitor provide very good soundstage. You'll not get depth, but the central soundstage with instruments position match that of my full range Neat Ultimatum XL6s, and my Meze Audio Empyrean headphones (that I also use in my desktop system from the iFI IDSD).
Good luck with your search.
