Yes, & what is being told to you is that this is so far an unrealised goal. You think measurements prove it has been achieved but others tell you that the measurements are not sensitive enough & they can hear differences your measurements don't reveal.I'm not working on any premise at all, micro, I'm talking about the theoretical goal of amplification -- to amplify without altering
That's silly - just because some level of equipment all performs in the same ball-park you then assume & distrust other equipment which performs at a higher level. I drive an ordinary car & it drives much like the other cars in it's price range. I recently drove a Porsche 911 Carrera & to lie that it wan't different or that it drove like other cars in it's class would make me a fool. I'm sure a F1 car will have a similar jump in performance because it's a money-no-object design with some innovations. You are dealing in absolutes, Tim, & forget that manufacturing has a budget & products are made to a budget. Your AV receivers are made to a budget & mostly follow the same approach to what they do. High-end gear either incorporates new design ideas, new technologies or expensive components. To try to make the argument you make about AV equipment is naive & silly-- and I'm supposing that if the very best amplifiers sound as different as audiophiles imagine they do, they are failing at something that common AV receivers get reasonably close to.
Yes & preserving this signal perfectly is the as yet unachieved goal. You argue that it has been done within audible limits & use measurements as your proof, others argue that it hasn't been & use hearing as evidence.An amplifiers musical message, its entire message, the whole of its reality is the input signal. It has nothing else. It is not sentient. It cannot look beyond the input and see anything else....
I have no good reason to believe that we cannot test the fidelity an amp's output to its input, and neither do you. There are, however, good reasons to believe that which can be heard can be measured.
Tim
And I'm telling them that they're wrong, that modern equipment can measure anything that can be heard. I believe I'm right about that. I await evidence to the contrary. I'm asked to prove negatives around here all the time. Enjoy.but others tell you that the measurements are not sensitive enough & they can hear differences your measurements don't reveal.
One of these days I'm going to learn to stop putting casual examples and metaphors in these posts. Someone almost always takes them literally, and makes them the central point. All I was really trying to say is that, according to Audiophiles, there is this dramatic, obvious, night and day, anyone can hear it difference between amps, even, if not especially, the very best amps. Given an amp's basic purpose, that can only mean one of two things: 1) These amps are being deliberately "voiced." 2) Even at the very highest levels, after all these years in a deeply mature technology, our best designers are failing and at a dramatic, obvious, night and day, anyone can hear it level.That's silly - just because some level of equipment all performs in the same ball-park you then assume & distrust other equipment which performs at a higher level.
I have given you a video which disproves what you say in the case of DACs, - what do you have to say about this? You don't believe him? You would like to see the evidence? Or like some here state, unless it's actually done in your presence you will not believe it - a Randi technique, I believe!
Enough to follow along the main melody and rhythm I should have said. Sorry about that. The track used can be an instrumental.
If my wife didn't use them all for skeet practice.No CDs lying around the house you could rip Bill?
Tim, I believe your statements to date are along the lines that the amplifiers sound so alike that there really is not much between them. You gave the example of AV receivers being so alike then why aren't high-end amps the same & you're contention seems to be they are very similar - it's just those dam audiophiles exaggerating everything. Yes, they probably do but the AV receivers are manufactured to a price point & so sound the same.
You are focussing on the hyperbole that is used by lots of people with a hobby such as this. You will get the same hyperbole with cars, art, music, etc. So what, take it for what it is, over-excited, over-exaggeration, delight. What's the big deal? You seem to treat it like some sort of lie whereas most take it for what it is - the over-exaggeration that goes with all hobbies. It's what this forum is about "what's best". If you think this is an over-exaggerated goal then why are you posting on such a forum?
I posted a video from the Chief Engineer & CTO of ESS where, according to him, they routinely use selected audiophiles to spot differences that his measurements don't show! So what if they are small differences, this is the level of refinement that we are at in audio now! remember, "What's Best"

Slides: http://www.esstech.com/pdf/noise-shaping-sigma-delta.pdf
Audiophiles were able to hear differences between Sigma-Delta & Multibit non-S-D DACs that the conventional measurements FFT or otherwise did not reveal. They have now correlated these audible differences with measured differences in:
- noise modulation
- phase modulation
Yes, they are now measuring these (not with FFT) but they would never have even thought of or tried to measure them if the audiophiles had not been used as a validation check. As far as they were concerned the two devices measured identically & therefore there should be no audible difference. Secondly they don't know why or how the phase modulation is audible.
So they are now using new measurements (in their portfolio) solely because it correlates with what the audiophiles hear not because they have any theoretical underpinnings for using it.

Yay! Okay this is just for fun now okay?
I'm using a macbook, iTunes and the iTunes EQ. EQ's might be different with those using other players but that's cool.
1. choose any track
2. open your eq window
3. drop all virtual faders to the minimum except 1kHz which will remain at 0dB
4. max out your computer's volume
5. play the track and drop your computer's volume until you can't hear anything
6. raise the 1kHz fader until you can sing along
7. play 3 random tracks and take note of your impressions of each and please share them
So, what does this show?
He's never going to tell us. Or, he went to sleep. Isn't it yesterday, or tomorrow in his time zone?That we like Jack enough to jump through a few hoops for him?Just kidding. I'm curious too.
Tim
The ways that have been suggested until now (null tests, fast blind tests) are not accepted by most audiophiles.
That a whole lot more of the content of jazz and rock recordings is in a very narrow midrange band, and that I can hear 1k pretty good, in spite of my advancing years.

Are you making a reference to me?-snip-
Another part is that I know that for every one of the raging subjectivists or vendors selling solutions here,
So you're the self-appointed Raph Nader of WBF protecting the poor foolish consumer who falls for all the confidence trickster vendors & you are nailing them with your incisive critique? Please, this smacks too much of messiah complexthere are at least one or two members rolling their eyes who appreciate my push back. I know this because I hear from them regularly. So, I enjoy it, so do others. Good enough for me.
That's your opinion because you have admitted that you have never heard the differences that are being spoken of & therefore you think it all hyperbole!But and it may be last, but it's definitely not least, this forum is "What's Best," not "What's Different," and when you get down to the kinds of insignificant differences we suffer over, differences that, as I've said before will more often than not go unheard if you don't know precisely what to listen for, it is unquestionably a judgement call.
You are the entitled to your opinion but it is simply your opinion - don't try to make it the opinion of a church that you claim to represent.And there's just something in me that has a hard time letting what's more expensive or what's more tweaky, or what's more exclusive, or what's more anal retentive, or what I have = What's Best, pass by unchallenged. I'm compelled to question it, because I know it's not anywhere near that clear.
I don't know what you are saying here - are you admitting that "all things audible are not measurable"?So ultimately it was measurable, they just weren't measuring the right things. Thanks for the confirmation. I really don't mind being wrong and suspect that in the absolute sense I am wrong about all things audible being measurable. But it's good to know I haven't gotten there yet.
Tim
Not really.... I'm pretty sure that's a pretty wide Q and you're still getting a lot of content 3-4 octaves up and down.![]()

t it is simply your opinion - don't try to make it the opinion of a church that you claim to represent.
I would appreciate you not saying this " for every one of the raging subjectivists or vendors selling solutions here, there are at least one or two members rolling their eyes who appreciate my push back." You imply that there is something amiss with what I'm selling so if you think so say so & stop making these associations between "raging subjectivists" "vendors" "members rolling their eyes". be honest & say what you feel instead of trying insinuation!Well, you are selling a solution, but I don't know that it isn't a very real solution to a very real problem, John. I've never heard your product or the one you modify, so I can't judge.
Again, Tim, say what you mean clearly - it helps for real communication, if that's of interest to you? If it's not of interest, fine!I don't know what you are saying here - are you admitting that "all things audible are not measurable"?
Re-read. Slowly. You'll get it.
Tim
