KEF LS50 or Harbeth P3ESR for desktop system?

Currently:

Spendor S3/5
SVS SB-1000 sub
McCormack modified Micro Power Drive
McCormack Micro Line Drive
HRT Music Streamer II DAC connected to the PC
AQ cabling

Speakers are 5' apart on the desk.  2' from back wall, no side walls within 6', vaulted ceiling.
Near field - I'm 5' away from them.

Piano jazz, movies on the PC, podcasts.  I don't try to break my ears.

There's absolutely nothing wrong with the current setup, but, well, you know...

KEF LS50 (not wireless), or Harbeth P3ESR (maybe even Anniversary Edition)?

Thanks,
Bruce
