LSA Voyager GAN Amplifier

What is so funny is that these "science is truth" people have no truth.   There are no double blind linstening tests that confirm one measurement is better than another.

These statements are false as are some of the apocryphal claims that followed them in the same post. Dr. Earl Geddes used double blind testing to show that off axis response and total room energy were extremely valuable for a speaker to be considered musical- and thus backing the measurements. Again, the important thing here is that if you cannot correlate the measurement with the apparent listening experience, you are measuring the wrong thing.

When someone claims numbers, science, engineering, etc., doesn’t matter, that it’s a scam, a religion, all faith, especially someone whose livelihood is dependent on denying anything that might give evidence of the veracity of his claims, it is an obvious and clear fraud.

+1 Exactly! Yet oddly, those same people will take a ride on an airplane, use electric lighting, the Internet and a host of other technologies all in a single day, and all that only exist entirely due to science and engineering.

Ralph,

You know very well we are talking about electronics here......of course, certain measurements of speakers are very important. 

For electronics.....preamps...amps....DACs.....and for all passive components,, tweaking and execution (like damping and shielding and grounding, etc.).....please show me the double blind listening test results.....come on.....do it.....you cannot....because it has never been done.  The only double blind tests that were ever done showed that people cannot hear anything in a double blind test........so show me the results of phase shift of an amp....or .001 versus .1 percent distortion.....or more second harmonic distortion and less upper harmonics or anything for that matter....It has never been done.  With electronics, passive components and execution.......there has never been a double blind test done......please show me....make me wrong.  I am sure you will find a doulble blind test that was inconclusive.......but actually shows something?.........come on.....no talk now......lets see the tests.

I never said that numbers and science and engineering do not matter........but that measured distortion numbers and signal to noise, etc.....have any correlation to sound?......show me.  show me the test results that prove it.

@jerryg123 Thanks, much appreciated, but no real need. When the Voyager and the GAN400 first hit the market, there was some scuttlebutt that the componentry inside the two units was essentially the same, but housed in very different cases. While having the same reservations as most about ASF, the photos they provided of the inside of the Voyager were interesting, and I was just curious whether (a) the scuttlebutt was true, and (b) there was a better layout inside the Peachtree.

Very interesting what you say about the new Bel Canto. Just curious, did you ever consider a Benchmark?

Hp 8903B Old but it does the job.

Clearly some ’tube guys’ do have analyzers on hand...

That old junker maxes out at -80dB THD+N. Useless for modern audio gear engineering. Especially for class D design work. No wonder you didn’t know Johnson noise existed. With my analyzer cheap dummy loads have a -92dB noise floor. But your analyzer wouldn’t even pick that up.

Come over to my place with a bottle of Whiskey Ric. I can show you how an audio analyzer can be used to make better sounding gear. Most industry standard measurements are useless for anything but marketing purposes though. And the tin ears over on ASR will be the first to mislead you on what to measure for.
