Industry accommodation pricing to reviewers is intrinsically corrupting. Saying so doesn't mean there are no honest assessments uttered about gear acquired at half-list and therefore, say, 35 percentage points below what a savvy consumer pays, but the reader/viewer has to suspect otherwise. Why? If a reviewer has a system, or substantial portions of one, assembled from half-price components, it is almost certain they get to own and listen to a system that would otherwise be out of reach if said reviewer had to pay street prices. Is it unreasonable to presume they are grateful for that? So at the end of the day, without accommodation pricing, most reviewers would be living with and listening to lesser hifi systems. It also makes likely that loaned "reference" components will be evaluated in context of not-quite-reference gear. Accommodation prices can inflate reviewers' sense of self-importance and undermine objectivity.
Concomitantly, long term loans of gear to reviewers by manufacturers effectively become lived-with domestic objects virtually indistinguishable from items a reviewer may have paid for. We can debate where the line is, but I think that no loan to a reviewer should exceed six months. If you can't assess an item or even a system with six months of daily exposure to it -- especially as a full-time reviewer -- you are either woefully inefficient, lazy, overscheduled, undisciplined, confused or critically arrested. You can delay writing or recording your review if you need more time to consider your copious notes (you did take notes, right?). That's up to the reviewer. But manufacturers should issue that freight call tag on schedule, or sooner if the reviewer volunteers.
Pearson even more than Holt, planted the idea that hifi reviewing was / is some kind of high subjective art, and that there was something intrinsically valuable about it. There isn't. It's useful to some people, but it's not a valuable human pursuit. A true 1st world indulgence. It's not that difficult. Listen, compare, assess in six months or less, get organized to write or record, move on. It's all going to disappear into the great digital gyre, occasionally pulled from the muck by a search engine or a persisting link, but ultimately obsolesced and forgotten. None of this is important enough to pretend you need to have something for a year, two or three to know what you think about it. Music reviewing is a higher calling than assessments of audio gear, and that still has its foibles. This goes for cars, watches....all the 1st world gear-based hobbies and distractions. But at least in their heyday, the car mags had some friggin' great writers, and they had far better skills for making a car's driving experience vividly palpable to you than any audio reviewer attempting to help you understand a lump of hifi gear. And that includes Pearson. Hartley, et al are whiffs.
Accommodation pricing was originally offered to (underpaid) retail staff and channel owners who sold your product, and to employees of other business partners, friends & family, etc. It didn't start with reviewers, because...well....magazines weren't accommodating manufacturers on advertising pricing, except by price sheet volumes. Some people argued then that the practice was corrupting to sales people recommending products to customers, but it was common knowledge that any possible compromise caused by accommodation pricing was dwarfed by the practice of manufacturers or distributors putting "spiffs" (direct payments to salespeople for selling preferred items) on stuff they needed to move. And dwarfed by the influence of commission-based selling.
But a reviewer isn't in that economic sphere. They are selling trust on a presumption of competence, honesty and an ability to make their assessment comprehensible and meaningful to their audience, for whatever reason.
At the very least, be willing to say something to the effect of, "My hifi includes a bunch of components I got at prices only available to industry insiders like me, most of which I couldn't otherwise afford, or even if I could swing the price you'd pay, I like saving money whenever possible! And I get to have a system at a higher level so I get to review more fun things that I otherwise wouldn't have peer gear for. But don't for a moment doubt my objectivity on gear I bought at prices you can't get!" Na na na na na na; your mother wears army boots, and all that.
