Another good find Warehouse. We call this "badge engineering" within the industry as the only thing that is changed ( in many cases ) is what name or "badge" the component ends up wearing.
I do have one problem with the article though. It stems from this quote: "Being a EE myself, with experience in working with reference designs for OEM purposes, I know that the changes one can make are minor at best, so I find that response a bit perplexing."
I disagree with this to a very great extent. It is possible to use the same power supply, chassis, circuit board, basic circuit design, etc.. and come out with a VERY different product. If this were not the case, "tweakers" wouldn't be gaining anything by swapping / bypassing / upgrading parts and manufacturers wouldn't be coming out with revisions 1, 2, 3 & 4 using nearly identical circuits in the same box. Even though the writer did us a favor by covering such a topic, he tainted the total package by adding in that last statement. The scary part is that many EE's think the same way that he does i.e. it all measures close, so it will perform / sound the same. As any of us that have ever modified circuitry can attest to from first hand experience, such is not the case. Then again, the EE's designing many of these products never get to see or use them at all. If they did, they would surely be more user friendly : ) Sean
