I have a pair of Chartwell LS3/5As that were my neighbors. He used them just as you describe, on his desk at ~2 feet as computer monitors powered by a (IIRC) mid-line Pioneer receiver.
When he passed away, his kids cleaned out the house and gave them to me (mint condition) with an extra, NOS, matching woofer.
They sound very, very sweet, but I don’t listen to them because my room is very large (~5,000 cu ft) and I would hate to blow them out with too much power/volume.
