Recommend a desktop nearfield speaker for me

For your listening distance nearly any loudspeakerswill work

We got fabulous sound out of atc which are very inefficient with a 40 watt naim if the roon is small and the distance is so short 5 watts will get you plenty of volume let alone 20

I have an Audioengine class D small footprint amp, a Jamo upright pancake sub, and original Kef LS50 speakers. This nearfield desk system is absolutely superb sounding. Apple music and Alexa are my sources. I have stereo setups around my house, and these speakers are as good as any of them (ESS AMT1b, Magneplanar) Happy listening!

@deep_333 Are "point source" speakers like the KEF LS50 Meta always better than something like a Harbeth or Falcon LS3/5A-style speaker, for nearfield listening? I do value good imaging.

Vangaurd Scout speakers at Vera Fi Audio $299 per pair. I've seen several good reviews, and they can be combined with the Vera-Link powered bluetooth for and extra $200......for wireless use

"Better" is going to be a very relative judgement here.

First, manufacturers provide minimum suggested power requirements based on their statistical measurement analyses of their product under rigidly controlled conditions in order to define a base of repeatable performance.  Accordingly, you should use them as a guide, but only a guide.  Your desk is not a rigidly controlled and repeatable environment.  In the real world, more power is a means to exert tighter control over a dynamic element at any given output.  Thus, one could argue that you should obtain a better image at lower output with a more powerful amp.  Only your ears can make that judgement for you.

Second, understanding of electromechanical dynamics, the electronic devices that control them and the eternal quest for efficiency (read lower cost) has grown substantially since the BBC developed the LS3/5A design.  One could argue that the KEF LS50 is the modern iteration of the first truly successful broadcast monitor design that they themselves produced drivers for way back in the day.  Having recently auditioned modern KEF dual concentric speakers, I would posit that the engineering has progressed to a point where the two approaches have diverged entirely.  They do similar work, but are no longer designed to the same purpose.  Only your ears can decide which approach suits your purpose. 

Finally, the LS3/5A design was most famously produced by Rogers for decades.  Since then, ATC, Falcon, Graham Audio, Harbeth, PMC, Spendor and Stirling have produced the same basic speaker in 8, 11 and 15 ohm variants using Celestion, Falcon, KEF, Rogers and other British drive units.  Why would so many different companies produce so many minor variations on the same theme for so many years?  Because the basic design does precisely what it was intended to do.

Since the deciding factor will be how you like the sound, audition the LS50 and any of the more traditional LS3/5A designs, then buy the pair you like the most.  Then sit down and enjoy the music because at that point, everything else is merely a distraction to the goal:  Happy listening.
