Car companies make great claims with respect to gas mileage and then they add a little disclaimer.
Your Mileage May Vary.
Isn’t it the truth? No matter what we or any other manufacturer might claim for what you should expect, your mileage will vary.
The question is, how much?
Fortunately, as with any well made and engineered product, there’s a minimum performance we can expect. When I write to you that one of our amplifiers does this or that or can hold its own against anything else out there, you can reasonably expect that to be true.
How close to duplicating what we hear in our listening room varies, of course, on any number of facts: your room, cables, source material.
There’s little reason to worry that bringing home a product for evaluation is risky in the sense that it won’t come close to your expectations.
As long as the company you’re working with has a good reputation for holding true to its word, the fact that your mileage may vary should be little more than background noise as opposed to a roadblock.
