@ctsooner is entirely correct. Imagine the attitude most companies would take to the reviewer who panned their product, and to the mag that published it. Are they going to be queuing up to lend other $$$ units for them to review? Likewise other companies, when a reviewer gets a reputation for publishing unfavorable commentary, how many companies are going to risk a review from that person? Reviewers, mags and companies are locked in a symbiotic relationship, wherein the companies provide, rent-free, long-term expensive loaners. How are they going to feel when that gets repaid in a certain way?
BTW, that's why many (not all) reviewers also shy away from comparative reviews. Even if they like product A and B, if they say A is better, what does that do to B's sales? There's only a certain number of punters in the market for that item, and this kind of review can literally sink a product, and occasionally a company.
Paradigm exemplifies a certain "modern" sound apparently aimed for by not a few current speaker companies, large and small, and which has little to do with the long-term, non-fatiguing enjoyment of music.
Finally, even if those models by Thiel and Vandersteen are similar in design (are they?), I greatly doubt they sound anything like the same.
