The IA 40.1 has a better reputation but it's the same thing on the inside as the XXV Goliath yes. If they laughed it's because they are ignorant.
When I first got into working on amps, first thing that suprized me was the similar designs and parts used in so many different brands, and then I was really shocked when I started to see the same boards in amps that are twice as expensive and/or 2 amps, one with a good rep, the other with a bad rep....
I was like everyone else who is "green" about ampifiers and thought that all companies that made them used different designs parts etc.... Boy was I wrong, that went out in the 80's and 90's... Lots of people still don't know this.....
The reason I get on here and point out similarities and differences in amplifiers is not to just be bashing or promote certain products.... What I would like to see is some NEW RESEARCH AND DEVELOPMENT.... Yes I am yelling it out to all the Audio companies out there.... Fire all your marketing dweebs who can't design an amplifier to save the world, hire some engineers and design and build some new shiz... stop buying the cookie cutter stuff from the build houses and putting your own name on it!!!!!
LOL I so wish that would happen but I doubt it in this economy and given the reduced state of the Car Audio business in general. Don't get me wrong, not all of the "cookie cutter" designs are bad, there are good ones, and some companies do more than just market their products, some actually improve on them on a regular basis, but it would be nice to see some new better designs.... Not just more power for less money and let build quality be the least concern.... shouldn't be that way....
