Great post. But this begs the question of why are so few capable of setting them up? Why not just fly in the German guys to set it at the dealers, at least ? And at all the shows, since the intro of the duo sounded so mediocre at both Axpona and Seattle.I find the AG Trio G3 system to be either the audiophiles dream come true or their greatest nighmare. It is a speaker system that (with the iTron) is extremely revealing and transparent to everything. Anything one does to the system is very easily heard. Dificiencies in any feeding electronics will be shown with a spot light. Differences in cables are trival to hear. Even very minute tweaks can be assessed. I mentioned in another thread that I had a friend over and I took 1 furutech cable lifter and placed it under the interconnect from the preamp to the speaker and the difference was obvious. (No other cale lifters in the system). I have not experienced this level of transparency with any other speaker I have owned or heard. I can use all of this information to make very precise changes to improve the sound (not just change it). Most of this has to do with lowering or manipulating the noise floor.
I believe noise floor leads us to why AG chooses solid state over tubes. Most tube gear is noisy. I don't necessarily mean the kind of noise you hear when you get close to the tweeter but some electronics do exhibit this kind of noise as well. I mean the insidious kind of noise that is riding along with the music. This is why the AG preamp runs with batteries -- less noise. With 109 dB efficient speakers we hear everything. To me, the quieter the component the better.
Tubes vs solid state. The old debate that continues. With the Trios I think it comes down to this: Do you like a rounded sound or do you like a more precise sound. With the iTron amp AG has provided the ultimate in precision. It is lighting fast and nothing gets lost in the timing accuracy of the speaker (I say nothing but in fact nothing is exactly perfect. The iTron is as close as I think anything has come)
So here is the dilemma and the nighmare part. The Trios are, in fact, quite difficult to setup to take full advantage of the great amount of precision the iTron offers. The speaker needs to be time aligned with itself and with the other speaker. Then we have to align the space horn at somewhere around 100Hz. All of this is not easy to do. It is easy to get lost and make the speaker sound really, really bad. So what to do? Well, one could just point the speakers pretty much straight ahead or give them a little toe-in but keep the ear out of the tweeter window. The sound is still quite good this way but certainly not precise. If one is going to go this way then choose your favorite SET and enjoy the lushness of it all. Nothing wrong with that.
As far as comparing iTron to SET amps. I do not see how the speakers can sit in the same position and someone can fully hear what each amplifier type has to offer. If the speaker is optimized for the iTron then the SET is going to show deficiencies. If the speaker is setup for the SET then the iTron is going to show deficiencies. I know AG offers the built in switch thing. When I was first considering it I did the demo just like everyone else. But honestly, neither one sounded all that great. (I commented on this in several other posts so if you are interested you can read what I thought of the AG Trio G3 demos there.) So I guess you could say the speakers were not optimized for either. It all comes down to optimization and setup.
I have not heard from Germanboxers in a while. He got the Trios with both the iTron and the passive Crossover. He has the Mayer 300B. If he ever decides to rejoin maybe he can comment on the comparison between the iTron and his 300B amp.
I would encourage anyone who is interested in hearing what the iTron can really do in a Trio system to give Stirling Trayle a call and have him come dial in your speakers.
(many dealers are betting that the prospectI’ve customer will be blown away … but not the experienced guys…)
And preferably also have the German guys set up at customers!
