[QUOTE="goblues38, post: 1449698, member: 29724"] I will bite... Your audio signal starts at the source.....goes into what ever DAc (digital audio converter) you head unit has. Where it is converted (#1) to a low voltage signal. It is then sent the system amp and amplified (#2) to a high voltage siganl for your speakers. at this point the sound has been manipulated 2 times and here is where the quality of your source matters. Cheap DAC's sound like ass, and what ever factory amp you have will make any bad qualities stand out like a sore thumb. Because we all know factory amps are not very good quality. Now...lets say you want to add an aftermarket amp. and dont want to spend the money to do it right ...So you convert (#3) high voltage speaker level back down to low level RCAs. Send it to your amp, where it is then amplified (#4) again back up to high voltage speaker level. So in this string....you now have 4 interaction points where you are manipulating your sound before it gets to your ears. 2 extra steps then just a basic DAC to amp set up. Ever copy and analog tape off another analog tape. the signal degradation compounds with each generation. Now...you may think you are ahead of me by adding an Audio Control Device that corrects (#5) any of the issues I have detailed above. But those things just compound the problem and what you get in final sound is NOT what was recorded. There is my rant. I am 50 years old and have been an audio nerd since I was 16 when i got my first job as a car audio installer. 34 years of experience in audio theory and evolution of electronics hold me to my opinion. High level speaker level inputs are bad and should be avoided at all costs. [/QUOTE]
