Mark xiii- it doesn't sound as if our listening impressions are that different. In comparing the construction of the Campanile Highs to the Triolons, there are many similarities but also some distinct differences. Probably the single defining difference is that the 4-10" SEAS drivers in the Campaniles cover the frequency range from 20-700hz while in the Triolons, a part of that range (170-700 hz) is covered by the new horn which employs a 12" woofer which is horn loaded. This very much changes the character of the mid bass making it faster, more dynamic and better controlled. In addition by allowing the SEAS drivers to focus on a smaller frequency range, it reduces IM distortion and improves the efficiency. The Triolon bass cabinets are somewhat larger, mainly deeper, and better damped/braced and moving the plasma tweeter from between the two sealed woofer enclosures and each side of the Campaniles seems to reduce acoustic breakthrough from the woofers from causing any smearing of the high frequencies. In general the Triolons are about 300# a side heavier than the Campaniles, most of which is in the woofer cabinets. The tweeter and smaller horn appear to be the same as you mentioned. Internally, I have no idea if there are parts changes except that the crossover must be more complex to account for the addional horn and is now divided between two enclosures. I can also say that bi-wiring or tri-wiring the speakers makes a rather significant improvement over using the jumpers provided.
Like you, I find certain things that I like about using a really good transistor amp on the speakers, particularly with respect to bass contol, bass slam, dynamics and top end extension, but am willing to sacrifice some of this and accept the somewhat looser (some would argue more acccurate bass)that is produced by the Einstein OTL's if that means that I get the top end and midrange of the OTL's. As you have heard both the Einstein OTL's and the FM Acoustics at the show and recognized their different strengths, what would your choice be for driving a set of Triolons?
