Sonus Faber Amati Homage versus Vandersteen 5A

Ok, I have to speak in order to stop people like Stevecham from making incorrect claims.

Sound speed is definitely freq dependent. But in order to truly make a speaker time correct, you will need to have infinite number of drivers to cover each freq and align them on different time axis. This is is not possible since each driver covers a certain freq range, not one freq, and the designer "picks" a freq to time align it. Not the whole freq range since it's not possible. Therefore reviewer tests the same way, one freq on tweeter axis. So if the reviewer doesn't test the designer's freq, it will not appear time correct.

As for phase correct, the worst thing to do is to use anything higher than 1st order crossover like in Thiel. This is a common sense and often practiced by well regarded manufacture including Sonus Faber and Dynaudio. I challege Stevecham to solve an op-amp in 4 pole equation, it will involves 1st to 4th order slope and will show it's impossible to keep phase correct with high order x-over. I hold a MS in EE and have been in semicondutor field for 10+ years, it's almost embarrassing to hear people like Stevecham making unsound claim without any technical background.

And thank God there is people like Stevecham on earth to keep company like Thiel alive who picks equipment by one data set, not by his own ears.

And this site is great for people who listen with their ears, not for people who bash other manufactures without knowing what they are talking about.

Semi you are completely incorrect on this topic. Yo umay goad me but it won't work. Audiogoners are well educated and know the difference between reality and BS, which is what you are fermenting.

The input signal used for step reponse analysis covers the entire bandwidth, not just a single frequency as you indicate. Obviously your degrees were obtained by mail order. Semiconductors; what do they have to do with analog waveforms? Bunch of ones and zeros, like your logic.

Thiel uses first order crossovers. You are wrong on this also. Anyone else wantto challenge this or do you still want to sit alone on that throne of nails.

I chose my system based on my ears, not on specs.

"An op-amp in 4 pole equation" has nothing to with this topic. No s$#t crossover with higher than 6 dB oer octave will cause phase shift. 4th order causes 369 degrees near the crossover point. So what?

No further comments from me; I answered Dbk's question.

I suspect you are a little kid with a desire for a nice system. Go out get a job and earn it like I did. And wipe your nose and zip up your fly.

At least the user Worldcat hasnt entered into this thread.........

I suspected Stevecham was the same guy who worked in Music Lover Audio who bashed everything and discredited anything they didn't like. They claimed Dunlavy and Spectral were the most accurate products out there and anything else were not worth listening to even though they carried them. They even went as far to tell their customers they should not be in this hobby if customers did not agree with their "reference" system. So narrow minded.

Semicondutor is a billion times more advance than audio product, and that's why Applied Materials can be where they are today. What I learned from semicondutor is current metrology can't interpret all behaviors, let along audio measurements where only a VERY small handful of people are doing research on. Semiconductor has billion of dollars to back up this industry every year and there are still a lot to learn, Stevecham is so sure the one data from Stereophile explains everything? What a joke.

And if measurement alone will determine the sound, why buy Krell when Adcom will do since they all measure the same? And I bet Thiel CS6 won't measure that differently from CS3.6, why spend the extra money.

Go to school to learn how to interpret data and understand analog circuit design first before you argue with others and waste others time. BTW, my study was on digital, analog, and device physic.

Semi, who said above: "I suspected Stevecham was the same guy who worked in Music Lover Audio who bashed everything and discredited anything they didn't like."

"Stevecham is so sure the one data from Stereophile explains everything?"

I have absolutely no idea what you are saying. None of this even resembles reality or truth. There is good science, and there is bad science. You know nothing about me and this just vindicates my conclusion that you are a so-called "scientist" of the worst sort, making conclusions based on suspicions, not on reproducible, let alone verifiable, facts.

And by the way, Krell and Adcom don't measure the same. Some "engineer" you are. Grow up.

Get a life, loser.
