LSA Voyager GAN Amplifier

I have heard of those researchers and read much of what they did.  Again....none of them proved by double blind testing that electronics (or passive parts or execution) sound different because of distortion measurements.   Electronics practically all measure flat in frequency response.  Even with frequency response:  Have you ever had a 20 band equalizer with a 20K setting and moved it down -2db?  Do you think you can hear that?  Most of us here do not hear above 14K.  Of course, if you did 1K we would hear that quite a bit.  I am sure that different kinds of measured distortion are audible....like more odd harmonics or whatever.  However, there has never been a double blind test that shows this.....or any other test on distorion measurements....please find one.  Until they do these tests.....it is all just the subjective opinion of the person doing the change that we here about.  Nelson Pass says he hears a difference.  I believe him.  However, he has no proof. 

By the way, Nelson Pass told me that he believes that "What I do works, but he has no interest in it."  He likes playing with ciruits and transistors.  He does not want to go down the rabbit hole of infinite tweaking.  This was a response from him....after I told him I could come to his factory and help him tweak his components.  This tweak game is time consuming.  He makes plenty of money making products the way he does and is very happy.  No problem.....we all have different desires.

Speakers are another story.....the frequency response, polar patterns, waterfall plots, impulse response, time alignment and distortion....all all quite gross and audible....and easily noticed on blind studies.  We are talking electronics here.  Please show me the study that shows how distortion numbers correlate to sound.  

Since this has gone into so many tangents...here's another one

Jaymark: how does the X5 midrange sound?

I'm into OB too, although DIY, and have the same Beyma AMT and wonder how those Deltalite 2512 mids sound and your experience with potential beaming from a 12" mid. Love the high sensitivity midranges. Never heard a 12" though (have 8").

Cheers!

Your statement above shows that you have spent 0 effort trying to understand how the LSA amp would behave with a real load, and especially with the ops speakers. Instead you insist on grasping onto things like solder or connectors, or ... and no they have not wasted time on a double blind test, because that is just what it would be, a waste. I think if you search long and hard, though you may find one on capacitors in a cross-over, but the result will not be to your liking.

I have explained, in excruciating detail, how electronics, in this specific case, will absolutely effect listening impressions. I have brought you to the water, but I cannot make you drink.

I believe Nelson Pass was just being polite. Anything he has put down to paper (i.e. on the record) has been backed up by actual data, i.e. he tackled the potential for frequency response variance with cables. He has never, to my knowledge, given credence to "tweaks", but he understands his customer base, so he knows not to put them down either. It would not be good for business.

In terms of how distortion contributes to perceptions of sound, this is just every day common knowledge now (or should be if you are claiming to be an amp expert) including what we perceive as pleasant, unpleasant, how it may impact loudness impression, masking functions, etc. As always Google.

@ricevs you make @kuribo blood boil YOU, YOU CHARLATAN.

I had an interest in the Voyager amp in the title post but reading through what is here is such a waste of time and so unpleasant.  This site seems to be going to hell in a hurry.  Perhaps it is what some of these awful posters would like to see happen.
