Hi gang, I have a spare set of r-14m I am going to give to my mom. Looking at an amp for them that is 13wpc class D. She will not be listening to anything loud at all, but still concerned even tho klipsch are mega efficient, it may not be quite enough juice. Shes old and does not like to learn new tech things, so this amp is just on/off with volume. Another simple decent amp suggestion with basic controls and a little more juice, like 20-25wpc recommendations would be good as well. I know 20-25 be plenty based off of my usage.
