Bookshelf speakers for near-field (desktop) use


I am looking for a decent pair of new/used bookshelf speakers for near-field / desktop use. I plan to use this with my PC as the source. The speakers would go into a fairly small room but in the future, I may use these as a bedroom setup so it would be nice to have them be capable for both. 

I can power the speakers with either a PS Audio Sprout100, Anthem MRX510 or something I may buy in the future. I don't want to spend a ton on an amp to drive these speakers though. Budget is around $2,000. Just looking for great sound. I'm not a bass head so that's not a huge priority but the fuller the range in sound, the better. 

A few speakers that I have considered are: 

  • Buchardt S400 - Are they appropriate for desktop use though? 
  • KEF LS50 Passive - Used I can find one for around $800 or just buy new for ~$1,000
  • KEF LS50 Wireless - Good reviews, but about the same price as the Buchardt's

good advice.

Don't sell your Anthem 510. Whatever speakers you choose, having them on a desk means you absolutely need a correction tool. Arc2 is really good. Reflections make it impossible for any speaker to produce a flat response. Best is if you can place the speakers on stands in front of the desk.

Personal favourite desk monitors at the moment are Kef 201/2, ATC 12, Quested H108, Lipinski 505, Monitor Audio Studio. All crossed at 100 Hz to a sub for fullrange. Indeed very nice listening. Looking right into the recording.

Heard the Kef R3 and it's a very fine but for my liking a little too polite or should I say sofisticated speaker. Like the LS50 (wired or not). Too much bass. That was only a first listening and your opinion may vary. Liked the R7 much more. Fine balance. Perfect (but polite) speaker for the price.
Ended up finding a good deal on the LS50 wireless and took the opportunity to give those a try. I'll post thoughts when I get them. If I don't like them, I think I can sell them rather easily at the price I got them so there is low risk to me. 
Get a pair of Klipschorns and suspend them on wires above your desk...it might not be exactly what you had in mind, but in MY mind this setup fosters an interesting image.
@chiptech10 Will see if that is the case when I get the LS50W next week. If it is, I may consider the LSX then. People do seem to be very impressed by them.
