Well Romy, IMO they are not just tonally different they are more tonally correct, ie. they simply have less coloration than other technologies. Just listen to a recording sometime made with a ribbon microphone and you will understand what I mean.

Since you don't "live" in this world I don't expect you to understand but my experiments with amps on my Apogees has shown that they work quite nicely with moderate power (in a moderate room of course). This hybrid amp that Dmitri (I think that's who) made for example would work marvelously on them. I have managed to get perfectly accpetable listening levels from them using a 20 watt SET amp. Why? three words. No thermal compression. Also, being a line source, the sound level drops with distance more slowly than a point source. So doubling of power really gives a true 3db increase in output. Levels up to 95db are possible at 3.5 meteres with 20 watts. The sound at 70db is still exquisite. The truth is that the 18 watt Lamm ML2 in a moderate room size (say 20 square meters) would do the job and sound wonderful. Perhaps you have never heard what it can do tonally?? Horns, regardless of how good, are always colored compared to a ribbon driver. In addition, there is now a guy in Australia who will be making essentially an Apogee clone but with high efficiency ribbon drivers and should be getting horn like sensitivity (ie. > 95db/watt) without horns. If you are not experienced with good ribbon designs I suggest you acquaint yourself (no Magnepan does not count). In truth, I like the best horn designs I have heard...better than any conventional speaker.

I don't hate you for misguided ramblings. Its like talking with a little precocious child Smile

. There is a reason microphones are either ribbon or electrostatic in nature. Response linearity, senstivity to small signals, low coloration, uniformity of drive etc. The speakers have the same advantages. Again, there are good designs and not good designs but that doesn't mean the concept is flawed in fact it is the best concept but difficult to execute properly.
