Looking for good bookshelf speakers less than $1k


I spend a LOT of time at my desk and want to upgrade my speakers, new or used would be ok.

My system is Jriver/Flac > Schiit Uber Bitfrost > NAD c356bee > B&W 601s2, and utilizing a Velodyne Impact 10 sub to supplement the bass.

Desk is 4'x5' and will be up against a wall in the family room. The speakers should work well on a desk really close to the wall. (the Revel M20 flush mount switch and high frequency control sounds like a good idea).

They probably should not be rear ported since they are so close to the wall?? And since they are so nearfield they should sound good with low volume, and I usually listen at lower volume anyway, but I like to crank it once in a while. I like a bit of a warm sound, however the B&W 601s2's are a little too warm and not much detail or bass slam.

I listen to a large variety of music with a huge interest in The Blues. Also listen to Jazz, Rock, anything acoustic, Indie, Alternative, Folk, Classical, Avantgarde.

My main system doesn't get used much since I'm at my desk most of the time. It's in a dedicated audio room. (Sony SACD 777ES > First Sound Presence Deluxe Mk II > Plinius SA100 MkIII > Von Schweikert Audio VR4->VR5).

TIA for any suggestions.

You can take the Harbeths off your list,they go for about
$1500 used. I have owned the Spendor SA1 ,Harbeth P3ESR and
Spendor 3/5R. If you are looking for warm sound the Spendor
3/5 (original)would go for under $700. I am not familiar with
the others on your list. Happy hunting!
Thanks Yogiboy and others who have given input. I could stretch my budget to $1500 if it was something that really impresses me and looked like a speaker to keep for a long time, a speaker to listen for extended time periods at fairly low volumes (occasionally cranking it up) and never feel fatigued. (however I would prefer to keep it around $1k or less).
Brand new Factory refurbed OHM Ls are an option worth considering. I bought my pair in 1978 when they sold for $500 a pair. I still have them and refurb and upgrade them as needed. OHM has been around for over 40 years and still supports every speaker they have ever made. I think the refurbs from OHM go for $600 now. Those are refurbed cabinets with new modern updated components to bring the sound into the 21th century.

Check the OHM "outlet store" here:

I see a pair available for $475 there currently.

The CAM models there also got a lot of good press back in their original day and are worth a look.
