I think it should be left up to the reviewers judgement on what the product will likely be used with and then trying the gear with a: his/her reference system with notes taken for the review, that provides a good idea of how it sounds/performs to the reviewer on what the reviewer knows the best. b: then try and put it in a system that matches the intended use and similar cost points. c: if available some form of vintage gear to A/B it against, that is the coolest thing since sliced bread and kudos to Affordable for doing this.
I enjoyed learing how both Todd and Stew do their reviews. They both took time to explain their gear and how they planned to conduct the -*test*-('")s. They asked for my suggestions too, which was cool. I just said however you want and that worked out just fine

I agree completely that you shouldn't buy based on a review, you have to find out for yourself, even word of mouth or friend's recommendation cannot predict your own ears. A good dealer will take the time with you.
I will state this again, Affordable$$Audio is the only reviewers that have:
a. contacted us.
b. did not say here's our rate sheet for advertising.
And that is cool. When I get a bad review from these guys, I'll know that the product needs some more work.
