This topic was discussed last year in "Recommendations for soundbar or similar for <$1k?" - but the soundbar was for use with a TV.

I'm looking for a quality soundbar or soundbase for use with a PC - for near-field listening to music at moderate volume + occasional movies.
I have a NAS full of 24-bit music.
Good sound quality is essential - I want good music, not cinema dialog, bangs, crashes and wollops.

REQUIREMENTS

For use on a desktop under a 32" monitor (see image below)
On a Lian-Li DK-01X Computer Desk (black with tinted glass top, 90 cm wide)
Stereo - not 2.1 or 5.1  
NO sub (I don't want or need one)
Compact - no more than 90 cm wide
Inconspicuous, preferably black
Good build quality
Wireless/Bluetooth optional
NOT Bose
Preferably <$1,000

I would value Geekzoners' advice

PS  The Sonos Playbar is an obvious candidate, but is probably "overkill"
