Rogers are always a pleasant experience. Not the most dynamic, they do not rumble, are less than painfully resolute, they are simply musical and pleasant.
They do change with upstream improvements and make polite accommodation for lesser quality components.
I have a pair of the original Rogers LS3/5A's. Bought from an eBay seller in Lithuania (!) for $960 (including shipping). These are the later 11 ohm version. The autoformer inductor used in the crossover of the 15 ohm versions was apparently too difficult to match individually so it was abandoned. SQ was claimed to remain unchanged.
They are pretty respectable speakers, but when comparing great monitors under $4k the Elac Vela 403 Beat them in every respect except for efficiency and $1k less money the Rodgers are smooth but not the most dynamic of speakers tested.
The best british monitor is the spendor s100 from 1989 to 1992 wait till you hear the 13.5 inch three way in the 1oo liter cabinet tuned to 24 hertz that is the only full range british monitor ever made and it is amazing.
I remember the dealer in San Diego, Audio Directions, sold them. One of the owners, Ike, liked to say there were practically no agreements in audio except that the LS3/5a was EVERYONE's second favorite speaker.
