If the word "mandatory" is freaking people out how about each publication developing its own "template" that their stable of reviewers would adhere to in order to insure some continuity and comprehensiveness to formally reviewed products. If I were the editor of such a magazine or online publication, I would suggest the following:
- Room dimensions along with any room treatments;
- Associated equipment;
- Statement of preferences--as an audiophile, what am I shooting for in terms of sonics;
- Relationship with manufacturer--any financial interest, discount offered on purchases, history with brand, etc.
Seems to me this would help the buying public make better sense of the reviewers findings.
