I have heard a number of single driver speakers that I have found enchanting (but not really exciting). These included several variants of the Lamhorns, Loth-X and the Ocellia. Of these, the Ocellia, which is based on a PHY driver, was by far the best. When you move up into the muti-driver speakers, and if you still want to stay SET efficient, the pickings become very slim indeed. Among these I consider the Fab Model 1 to be excellent if set up properly, used in a not-to-big room and driven with first class electronics (just like in Gliderguiders system). Even my Reference 3A Decapos are quite satisfactory with my 18 wpc KR SET amp, although I have mated them with subwoofers to cover the bottom octave or two. However, given a large enough room and sufficient power, none of these speakers comes even close to matching the dynamics, frequency extension (top and bottom) and imaging capability of the Total Victories. The TVs are simply stunning and certainly amoung the best speakers I have heard. Yes, you can use them with fairly low powered SETs (my KR will drive them quite adequately for lower volume listening) but they really need consideraly more power and control. A friend of mine is now using a pair of TVs with a Classe 2200 amp which, I think, puts out about 200 wpc. I did not believe that this combination would work but it is sublime. Sweet when required but incredibly forceful when needed (ie. large orchestra). His room is also quite large which definitely helps.
In other words, if your room is big enough to handle a large speaker and you have a good 50 watts or more, the TVs will out perform every single driver speaker and almost all multi driver speakers that I have heard in the past 35 yrs.
