Your qualifications do not contradict the fallacy of your statements; the amps' THD is less than .1%. No offense intended, but I've know idiots who have been in their field for far more than 20 years; that doesn't make them smarter, just dumb longer. If you *MUST* qualify yourself to make a statement, use achievement, not time. Take, for example, two USACi world finals qualifications. I could care less what "Audiophiles" think, it's still wrong. Distortion levels in 99% of the amplifiers produced today - including fosgate - are so far beyond audible limits that your suggestion of being able to discern the distortion is nothing more than silliness.
Incidentally, I do not, nor have I ever owned a Fosgate piece of equipment. I feel that they are overmarketed and overpriced. The difference between you and I is, quite simply, I choose not to buy a product for informed and understood reasons, and I do not choose to insult you, however inflammatory you attempt to be.
