So why cant that be the case with Rick upgrading these amps?
he doesn't upgrade, he modifies. And almost certainly based on his lack of fundamental knowledge of the circuitry, he degrades their performance to suit his own version of "good sound", fidelity to the input signal be damned.

If you were so swamped with work you wouldn't be constantly advertising here.
No doubt there are those who find value in your work. PT Barnum mentioned them I think.
|
But why do they keep him around? simply because he causes controversy. And that results in conversation. Which results in people coming to the forum to spend money.
Only rationale explanation. He's constantly shilling his business which most boards don't allow but apparently it's just fine here.
|
I will not give Bruno a single thought and will never own another piece of his junk again.
I'm sure there is something out there for you that sounds great in a cave.
|
Jerry was able to influence the mods.
Ya think?
|
All I suggested is just post impressions and ignore the irrelevant.
And how do you define "irrelevant"? Anything that conflicts with your opinion of this amp?
|
@kuribo What did you think of the amp?
I think I have made my opinion clear here- it's a poorly designed, poorly performing, and old tech. Poorly designed because it's using bridged stereo modules and prefilter feedback, poorly performing because it's frequency response is dependent on load, and old tech because class d amp design has advanced in the last 20 years to post filter feedback enabling the amp to function independent of load.
I am not addressing the subjective performance because that, due to the load dependence, depends on what load any individual user may be using as well as any individuals personal preferences, which can neither be quantified nor disputed.

He fixed the XLR
Nice of him.
|
If you are not willing to put in the effort to learn what is common knowledge to so many others in what appears to be your chosen field of business there is little I can do.
It's not in his financial interest to admit what others have proven in numerous studies. People who have swallowed the koolaid aren't interested in the truth, it's a faith based belief system.
|
because those components have that signature compared to straight wire. And this signature cannot be measured. Same with all audio wires. Some sound dull, some sound neutral and some sound bright (as well as other characteristics......mostly which CANNOT be measured).
Why? What is the physical mechanism that causes a passive length of wire to have a "sound signature"? If there is a physical mechanism, why can’t it be measured?
How do you quantify "neutral", "bright", "dull"? Compared to what? Hint: you can’t. These are all subjective descriptions with meaning only to you. Others may have a different interpretation, thus, your claim is true for a population of 1- you.
We can measure the objective performance and studies have shown correlation with those measurements with subjective opinions of "quality".
More "you can’t measure it, but trust me"....Praise the lord...
Do I like the fact that the LSA shows more roll off at lower impedance loads?....no, I don’t.
|
I have never said don’t listen as obviously that is what these devices are made for. What I have said is don’t give your money to charlatans who make claims without a shred of evidence, who like to tell everyone what sounds best, and who continue to preach and pontificate a religion while denigrating science. No one likes a parasite.
You want studies? Read Geddes, Hawsford, Otala, etc. You are the one making the claims, the burden is on you to provide evidence. But, you can't.
And I see you failed to answer my question- what is the physical mechanism that causes passive components to alter the input signal to such a degree that it is audible to the human ear?
|
how do you ever hope to design products that more than a few people will subjectively like?
He doesn't. He doesn't have the knowledge to design a class d amp. He just rides on the coat tails of others.
|
Well, there you have it from the horse's mouth: Nelson Pass discussing how different distortion components relate to perceptions of sound quality using SIT devices. Oh, and he discusses how measurements can predict sound quality, using measurements and then confirming with listening.
Brilliant.
|
Would you rather be Right or Loving?
I would rather you packed up and took your trippy snake oil sideshow somewhere else.
|
p.s. to those who called me an "armchair/wikipedia engineer", this is me having the last laugh.
Thank you for the intelligent, rationale, and reality based post. It’s refreshing to read something that actually says something meaningful rather than the "trust me" explanations all too common here. It’s also nice to see something that isn’t full of insults, posturing, and mental instability, written above a 4th grade level. Bravo!
Gee, so it seems you can't simply remove and replace important elements of the design without a thorough understanding of the component's role as a whole. Who would have thought?
|
No bother will be ignoring you.
Promise?
|
What I said was Pass cannot prove anything because he has not done blind testing.
Please tell us about your blind testing protocols and results for your claims regarding wire, solder, outlets, and all the rest.
|
LSA Voyager GAN 350 its problem is power wire (AC DC)only 16 AWG, that design was too little to good sound, 14 AWG or above is better .
That's the least of this amp's problems. The basic design is subpar.
|
"sonic distortion"
? New snake oil term?
"The measured distortion of an amp is only a measurement of about one one hundreth of its sonic distortion"
Any published evidence or more snake oil unproven claims?
"I made Bruno Putzey’s amp better"
Yeah, sure you did. If you knew 1/100 of what Bruno knows about amps you would be designing and selling your own instead of fabricating bs and leaching off the success of real audio designers and experts.
"There is no such thing as "distortion below audibility"
Really? So distortion components 200db down from the signal are audible? Yeah, right.
LMAO, what a joke. And people actually pay you money for this nonsense? Nice try Mr. Snake Oil but you are full of it.
|
@kuribo please enlighten us ignorant sods. Please explain the dynamics of harmonic suspension tuning.
Try Google. I don't have time to post a semester long class in dynamic systems. The point is you have no clue what you are doing and if it is genuinely affecting your system or all in your head.
|
So you are a freaking troll from that Facebook Hate Group.
Great comeback. It fails to address the issue at hand though, which is your ignorance of dynamic systems. It also has nothing to do with this LSA amp and it's poor implementation of the GaN tech.
|
You deny basic physics, invent "facts" which have no basis in reality, and keep preaching your faith based audio religion for profit. You are a scammer and should be banned.
|
Please guys.....do not respond or reply to George. He will just say the
same thing over and over again. He will fight, fight, fight you. It does
not matter to him that he has no proof of his 1.5 meg switching
superiority or necessity Kettle, meet pot! Ric the Tweaker who keeps saying the same bs over and over with no proof, is no different than that other class D dogmatist. At least George tries to offer some sort of rationale, but not Ric: "everything matters". He never includes the part about how most of his voodoo has never been proven to have any basis in fact or reality or the fact that human perception does indeed have limits. Oh, and there is also that pesky bit of reality he ignores called subjective opinion. All his tweaks make things "better". Better for his bank account, for sure, but do people honestly believe everyone has the same opinion/taste as to what is "better"? I am amazed at the people here who blindly drink the koolaid. A fool and his money... |
Sorry jerry, I didn't bring up ASR. But if I did, so what? Their review of the LSR amp is germane to this discussion. Just because you can't read and understand their technical critique of the shortcomings of this amp doesn't mean it isn't relevant. Nor does it matter if you agree or disagree with them.
Mike isn't my buddy. I don't find childish insults and mental instability attractive from anyone.
And I don't find unsubstantiated claims from audio shaman profiting off of the insecurities of others desirable either.
If you have an issue with these opinions, that's just too bad. Personally, I could say I don't think much of yours either, but that would be overstating things.
|
Oh, but jerry, it is my business as I don’t enjoy the constant shilling on what is suppose to be, as I understand it, a hobby site. I don’t come here to be spammed with incessant ads and audio quackery. I haven’t attacked Ric for his opinions, I have questioned the veracity of his outlandish and unsubstantiated claims. I have criticized his business model of constantly promoting his money making "improvements" on a hobby board.
And I don’t come here to be subjected to harassment and childish insults from petulant crybabies ignorant of the technical issues who can’t handle anything but never ending praise for their (poor) audio choices.
I get it, you like the amp, you believe in audio magic. Great! Go enjoy yourself.
I am not interested in saving anyone, least of all you.
|
Studies are out there. Do your own homework.
You speak for a population of 1 with your subjective "impressions". They have no validity for anyone else.
We have not invented a measurement tool that can tell us why parts, wires, brands of solder, etc. to infinity and execution make different sound.
Because it has never been established that they do.
More facts, substance, less religion.
|
jerry, it’s clear you don’t understand the difference between subjective opinion and objective fact, among many other things. It’s not possible to have an intelligent conversation with you, as you keep proving over and over with your incomprehensible blabbering. A lot of sound and fury, signifying nothing I am afraid. Get an education and some interpersonal relations counseling and come back when you have something civil and intelligent to add.
|
He then reviewed my modified $1650 (total with mods)
Another commercial announcement. You must be desperate for sales to be constantly pimping yourself here.
Does this prove anything? No......but which one would you want based on his ear?
No, it doesn’t prove anything. So why mention it? I couldn’t care less about the opinion of some web reviewer. Boring.
he rates the EVS modded VTV at 9.5 bordering on 10
Maybe it would have gotten a 10 if you hadn't messed with it.
|
Really sad that some people here have to resort to childish insults and name calling when they feel threatened by the opinions of others. One wonders about the mental health of people so willing to debase and embarrass themselves.
|
@cindyment Sadly, that is the only conclusion that can be drawn- too much noise, not enough signal.
|
There is zero correlation between measurements and the sound of electronics........please, again, i beg you to show me the double blind listening test results that show a correlation between measurements and sound quality.........where are they?
You just don't get it- you can't correlate something objective like actual measured physical phenomena like distortion with something subjective like "good sound", by definition. Yes, "good sound" is all in your head, and only yours.
|
I told Bruno the only way you would know if you got rid of the hysteresis in a ferrite coil would be to A/B his coil with an air core coil and listen. This is how you know somethng.....by actual listening tests......not by a made up measurement test that has no basis in sound quality.
Measurements are objective, they have no bias. They have a basis in reality, unlike subjective listening that varies from person to person. If there was one best sound, there wouldn’t be so many different and successful amps in the market place. Your idea of good sound is just that, your idea. It has no basis in reality for anyone else. Eye witness testimony has been proven time and again to be unreliable. Your ear witness testimony is flawed for the same reason. At least Bruno delivers an honest product that delivers as advertised, rather than some magic guru fantasy tweak that simply, at best, just adds more noise to the signal.
If Bruno listened to everything he did and was all knowing.....then maybe not. He does not listen to everything he does and is not all knowing.
Bruno produces products that amplify a signal as cleanly as possible. If people like distortion, they can add it themselves in any flavor they prefer. He doesn't push his subjective tastes on others and claim he knows what sounds "best" -he isn't all knowing but he does know that. I can't say the same for you.
