Hey there Alan! OK, let's follow this one on out . . .
If you were in the market for a train . . . would you go to the guy that is borrowing a train to drive (and can borrow trains at will), or to the owner/operator who bought the train, services the train, has to make a living with the train, might go out of business if the train is crappy, etc? Who has a more vested interest in discerning the train marketplace? I'm asking the latter guy for advice.
What if the DAC and train cost the same? (Oh . . . that's another thread)
Playing Devils Advocate here, but just like to say my position in somewhere between both points.
Jeff, by this logic this means a reader of a review should purchase only reviewed products that are actually purchased by professional reviewers.
Therefore, it could be argued following the logic of the one who borrows or purchased, that if the reviewer does not purchase all the gear he recommends that review is void.
But, as a case in point I am sure you do not purchase every piece of hardware you have recommended, resulting in those instances of it falling into the borrowed category.
This rule of thumb may need some leeway and flexibility otherwise most of a reviewer's work will never be published, and that would also be applicable to Soundstage.
Cheers
