You're welcome Hudson,
I'm contemplating the RF7's now and my only amplification is a Denon reciever by itself or used as a pre with a 120 watt Sonographe (conrad johnson) stereo amp.
If I get these 7's, later on down the road I suppose I could try one of those Carver's with a tube pre or possibly the Rotel or even some older rebuilt stuff. Seems a lot of people are happy with what they own and have some convincing stories to go along with it.
lol..seems there are many different ways to power those 7's depending on ones own needs and preferences.
I'm keeping an eye on this thread...sure are some happy customers with this particular speaker....also anxious to hear how you like your system once it's in place.
............See Ya.
