Is B stock a safe bet?

I am sure that if you ask enough people there will be a bad story or two, but part of me likes the idea of "B" stock from the veiw of a serviced item returned to sell..... because I feel its flaws have been revealed and resolved, in alot of ways a "B" stock unit gets more testing and careful inspection then products that role off a line, and those can and do good bad. There is even statistics that suggest that as many as 1 in 5 Audio/Video componets have something wrong from the start, I have a dealer that sells NAD in my area and he goes as far as bench testing every single peice he sells, not that NAD has any more problems then others, it is just that it is almost routine to get a unit with some kind of flaw in it now and then BTW he sells Dennon also aswell as Definitive Tech and McIntosh.
Before I drift too far from a simple answer, I dont personally see any reason not to buy "B" stock from an AUTHORIZED dealer.

B-stock is checked completely. Sadly, all gear coming off production lines are not checked completely. Having been in the business in the past, I assure you that the best values and most carefully checked products are B-stock and refurbished gear.

Beware of sellers on Agon who list an item as "new" but don't disclose that it's B stock.
