I think any quality amplifier will drive the 15ohm Rogers with no risk to the speaker. Just use common sense and no wide open volume pots! I have a pair for over twenty-five years and have driven them with a Dynaco Stereo 70, Bedini 25/25, Quattre DGC-250 (solid state), Bryston 4B (solid state), NAD 3020 (solid state) and McCormack DNA-125 (also solid state). I have never experienced a problem with any of the set ups. The tubes were wonderful with them - seemed to ease the mid-bass bump a bit. Of the solid states, the McCormack was the hands down winner - almost fooled you into thinking it was tube. Hope this helps. Enjoy the little guys.
Rogers LS3/5a question
I am a pro audio guy and know very little about hi-fi stuff. I was at an estate sale today and found a pair of Rogers Ls3's for a VERY good price. They were built in 1079 and the construction is some of the best I have ever seen in a speaker. The problem is that they are 15 ohms and I really don't have anything to power them. I do not want to damage them by hooking them up to something I shouldn't. I would love to hear them and make sure everything works properly. From what I gather from a little research is that the mid-range is incredible. If they are better than my reference monitors I will keep them, if not they will be sold. Thanks for your help guys!
