I agree this an interesting conversation and only time will tell the final outcome. For me though I look at Trinnov as being another tool in the tool box. I myself have always believed that the path to a quality listening experience begins with the room itself. Therefore I will always address the basics and take the Trinnov or whatever other gizmo they can dream up and exploit it to the fullest. If it can help in creating a better listening environment then all the better. If it acts to reduce the quality of the environment then I will simply not utilize it.
I will say that I agree with altec in that many less informed users are going to think that this is the silver bullet they have all been waiting for all these years. But what's a guy to do... some people still think mp3's sound good. Anyway, it is ultimately up to the end user to educate themselves and if they choose not to do so then shame on them. All the advertising and marketing that takes place these days one has to be cautious. I know there are people out there like my parents who cannot work a telephone let alone successfully intergrate a new technology like Trinnov or Audyssey into their listening environments. But, there again I feel it would be wrong to sit still and not move forward with such technologies which could yield benefits for those willing to experiment. If nothing else it will be a fun way to waste a weekend.
