Graham Tricker (GT Audio) design his own high end tube amps specifically for the AG horns (he is the Uk distributor for AG and he heled design the AG Model 5 amplifier).
With the AG horns, you need a really quiet amp with little noise. I've heard the TRONs at some length on several occasions. The background noise is silence with the AGs even with the volume turned up full using Trios. they sound great too.
Graham does have a US distributor, so you should be able to source a demo. If in doubt look at his web site (www.gtaudio.com) and email him.
