I looked at the avs thread, as well as a couple threads linked within those posts as well. Casey brings up a good point about the Classe Audio amps. They also list Krell, and McIntosh as other companies products that they "upgrade". I wonder if this individual has a bachelors, masters or even PhD in electrical engineering? How could he know more about electrical engineering than these companies, that do not compromise on the components that they use? I could understand upgrading a product that has been manufactured at a certain price point, and did possibly use components that were more cost effective, and could be replaced with better performing products manufactured to a tighter tolerance.

I have had Onkyo,Marantz,NAD, and Krell products. Honestly, i can not tell a difference between the NAD and Krell processors that i currently have. There is also no audible difference to me between my Marantz amp and my Krell amps. The ONLY difference between my amps, is the amount of power they are able to put out.

I currently have a Krell processor, and Krell amps powering my Axiom speakers. I like my axiom speakers. I think for the money the Axiom speakers are an extremely good value. Have i heard better speakers? Sure, however they cost 20k$ a pair.....
