Hi Jerry
In the past the industry press chose not to talk about Low Mass tuning after the original reviews were made on the systems we were converting (even for reviewers). It was a matter of economics for the magazines, ads = press. The best sounding systems were not the expensive ones at all, but instead were the carefully tuned ones.
The technical reasons for the performance gains confused high end audio because they (HEA) had built a premise that didn't work, but they were already in up to their bank accounts. Even though some of us warned of chassis interference the high end jumped onboard bigger is better and went the opposite direction from what they should have.
Now that innovation is back in the driver seat the hobby is literally changing before our ears.
