Actually, 2006 was the year they started straightening out their problems. I have not heard a 2006 side by side with a new one, but I have used a 2006 810e in the last year, and it sounded better to me than the others. Not sure why, but it did seem to have high end that was lacking in the ones made in the previous few years.
Nice avatar, BTW
Those were fun times a year and a half ago!
