Please help me understand


There are two concepts I've never been able to reconcile. How is it possible for different amps to have similar distortion levels (inaudible), yet still have what audiophiles might describe as a "tonal signature". In other words, how is it possible for an amp to have a perceived "warm" or "bright" sound, if it's accurately reproducing the input signal? It seems to me that all high quality, properly functioning amps should sound the same. If they don't, them some of them aren't doing their job very well.

Rok2id,
Who`s discounting science?it can explain alot but not 'every thing'. Certainly we`re able to detect audible characteristics with our ears that can`t be verified by measurements(yet), Why is that so hard to except. We can measure many things we could`nt 30 years ago and I`m sure in the future we`ll measure things we can`t today. In the mean while we have ears to rely on. Rok2id I`ll assume when you audition and decide to purchase your'audio' components you listened to them rather then just read the measurements and buy based on that criteria alone. Science is great but it does`nt at this stage have all the answers.
"The human ear is more sensitive than any measuring tool."

My post was primarily in response to the statement above. It should be self-evident that human senses, among the animal kingdom, SUCK!! we build machines all the time, to see, hear, smell, and detect things that human senses cannot. We have systems on submarines that can ID other subs by the sound they make. I am sure a machine can be built to ID every amp on the planet, based of that amp's output of a known input. But, who would want to do that? My post may have been an over statement, but if people say they can hear wire and amps and all the rest, FINE! Just leave science out of it.
Just food for thought, your family pet 'hears' more of your high-end system than you do. :) Maybe we need a K-9 audiogon hahahahahah those would be some interesting threads!!
Peace.
Another point not really mentioned much here is that equipment designers do not just use measurements/science, they also use their ears, and they design something that sounds good to them. The vast majority of them understand that it is all about the music and how it sounds, which is ultimately more of an aesthetic choice rather than a scientific one - a choice made with their ears, not their numbers.
"In the mean while we have ears to rely on. Rok2id I`ll assume when you audition and decide to purchase your'audio' components you listened to them rather then just read the measurements and buy based on that criteria alone. "

actually, that is exactly what I do. I have never auditioned a piece of gear, and that includes speakers. I bought my JBL 150s because they were 'known' to be good party speakers. I got my polk Ls90s, because AUDIO magazine said they sounded just as good as the high end stuff, and FT Hood got a truckload of them and sold them for 600 a pair. MSRP was 1600. I got my Polk Lsi 15s because they were said to be better than the Ls90s.

Sadly, my current and past gear has not been worthy of an audition. One more great thing about lo-fi. plus, you save on gas. My next speakers will cost around 5000, so there is an audition in my future. :)
