99badsvt,
I know that your info is very close to being right on, but i like to clear up some of the car audio myths that are so prevelant in the industry. It is nothing against you. Also, there are potential differences in sound between all of the amps I listed. My point is that you, in dbx testing, couldn't pick out one amp from another, much less pick out the Zapco and consider it best. Nothing against you or your ears, but this type of test has been done far too many times with people with ultra sensitive hearing, and no conclusive evidence has ever been extracted that anyone can tell the difference, hence Richard Clarks $10,000 amp challenge.
