My circa 1985 KEF 103/3's or my Denon AVR 3300? My system has been up and running for about 4 years now and, although it has been great--save the hissing noise I think I just fixed (see related thread)--it may have been incompatible all these years. The KEF 103/3's seem to be rated at 4 ohms "Suitable for use with amplifiers capable of providing between 50 and 200W into 4 ohms resistive load." (pulled from the KEF museum on the KEF website) On the back, they say, "for use with amplifiers up to 200W 4 ohms (100W 8 ohms) My Denon 3300 has a rated output of 105W per front channel at 8 ohms and 140W per front channel at 6 ohms. It clearly states that only speakers with an impedence from 6 to 16 ohms should be connected. I use the system a lot and it really doesn't get that hot. 1. Am I in trouble? 2. If I've made it 4 years, should I be OK? 3. What does the (100W 8 ohms) in parentheses mean? 4. If I need to dump one or the other, which should I dump? The ancient KEF 103/3's or the Denon 3300? Of note, I actually have 4 KEF 103/3's (two I don't really use right now but I used to use them as my surround rears) Embarrassed, AVnovice.
