I had a pair also back in 1980, the Swisstone models with the 15 ohm inputs.
A NAD 3020 and a Dynaco Stereo 70 made them sound quite nice.
But I was a musician at the time,and they just didn't have enough bass for me, and no sub at that time ever really matched up.
They imaged quite well, by that you got good spacing and layering of the players on the recording, but it was all miniature.
I sold them and went to Acoustat 3 medallian and this was closer to what my musician wants were at the time.
The deal closer for me was when I took the LS3/5A out of a small room into a large room. They just didn't do it anymore.
If you want to use them as monitors, keep them in a small space and you maybe quite pleased.
