Here again, as someone who has been around the A/V business as long as I have and seen most if not all what some people perceive in their minds as being money "well spent", charlatans like the Upgrade Company will, unfortunately, continue to exist. Do all these suckers not realize that pretty well all the parts that are being replaced to provide this so-called "superior" sound, are made in the same part of the world(Far East), similar parts to those that are in the unit already? It never ceases to amaze me what people will buy!

When it comes to this stuff, luckily for us, we know better.
