Negotiable, why lump some of our concerns as merely sour grapes, or a mysterious conspiracy, when we are actually talking about instances of collusion, and an editorial slant of avoiding discussion of a product weakness to procure, maintain, or augment ad revenues?
I found it disconcerting that Michael Fremer could write a review of the Continuum turntable, and then manage to finagle a three year grace loan from the manufacturer to purchase that said TT at an industry consideration price. Fremer has also stated that he has the luxury of always making a profit whenever he sells any gear, due to his sizeable purchase discount he enjoys as a reviewer. I would say this is a significant collusion that places a third party with economic interest at a disadvantage.
When I grew up and became a fan of Klipsch speakers, I always wondered why Klipsch could never get a speaker reviewed, and Paul Klipsch noted in person that he was not in the business of giving speakers away in order to get them reviewed.
Bill Dudleston of Legacy Audio has also made a similar observation, so it is not only dead people that have problems with reviewers not desiring to return costly gear.
The following has some interesting points made, some being sharper than what is allowed here, and the topic in general being freewheeling.
