Making a purchase decision based on these specifications is like rolling the dice in Las Vegas.. So it would appear that specs do not define the sound quality of amps. Thus all well-designed, similarly measuring amps do not sound the same. Or am I mis-reading here? |

Yes. *specs* are not the same as *measured performance*. below is a corrected version of Packer's *******ization of what I said http://groups.google.com/group/rec.a...44a6c3e558f35b "In the case of ATRAC encoding, 80% of the information is lost permanently. But, the energy contained in the audio signal remains about the same." They are both true statements. Got a problem with that? Something for Arny to explain to me at length in Paradise, where we'll all have a lot more time. The good news is that I'm not responsible for your errors and lying, Paul. You made you do it. |

I merely said that I'll have to get you to explain it more fully sometime. And incidentally, while I fully admit to errors (as indeed you would be wise to when appropriate), lying has nothing to do with it. |

Someone should explain to Mikey that this is why Arny is considered a nasty person Someone should explain to you that I don't give a ****. If I get the answers I want from him about the questions I ask, then he's done all I need him to do. He's never been anything but cordial to me and to those who have always been cordial to him. If he gets treated less than cordially he tends to hold a grudge, sorta like you against McCarty, or me. If your ego is so fragile that it can't stand somebody's criticism of you, especially when you're dead wrong, which happens a lot it seems, then **** off. You're obviously too big a candy ass to be here. |

Thus all well-designed, similarly measuring amps do not sound the same. Or am I mis-reading here? They don't, because the measurements used are antiquated, and not insightfull designed. All the quoted measurements are things an E.E. could do back in the 60's and 70's with a couple of test-tone oscillators, and some filters. It reminds me of the story about the drunk who lost his wallet, and spent the night circling a street lamp, staring at the ground. When asked why he spent all night looking in one location, he replied, "Because that's where the light is." There is a tendency of the engineering contingent of this group to be captured by what they consider "revealed truths"? It's as if they've grabbed a live wire; the electricity caused their hand to contract, and they can't let go. Of course, the cream of the profession evades this, but they are seldom represented here. Some of these people are not engineers at all; some are technical workers, and some are poseurs. Yet there is truth to the notion of the "engineering mentality". Part of this is due to self-selection; part is due to the way the curricula is taught. In fact, one of the things engineering students are taught is that it is simply impossible to think about every choice you have to make. It is better to know, than to "reinvent the wheel." But this has a bad effect. Minds that have a cosmic grasp can get beyond this, and become originators. Those who cannot can still be very good engineers, but as with any mechanistic frame of mind, sometimes end in ruts they cannot themselves perceive. |
