What should be mandatory in every professional published review-

Certified results of a recent hearing test as performed by a certified audiologist.

A full-disclosure statement by the reviewer of said reviewer’s preferences in "how reproduced music SHOULD sound" as well as her/his taste IN genres of music.

And finally, a statement by the reviewer that addresses the nature of relativity and subjectivity.

Just as I wouldn’t say something sounds good when it doesn’t, nor would I ever say something sounds bad when it doesn’t just to be “critical.”

My bad.  I meant (in hindsight)  to convey the word critique,  Not criticism.

Must be a tough gig.

How long can it float? 

About a day until the funeral directors come in to collect.

After that it is the duty of the plumbers.

Room size, flooring (concrete, wooden...), windows (my room the front wal has a very large glass window, back wall is 3 sided floor to ceiling glass windows, walls: concrete, lath, sheet rock wood studs or metal studs...,  treatments, carpeting,window shades, curtains heavy duty or..., dedicated line or not, 

I think it should be mandatory that the reviewer disclose whether he gets the piece of equipment for free, or at a discount that he is reviewing
