Just because someone disputes something it doesn't make it so. I can without a shadow of a doubt propose that you would be unable to distinguish hi bit rate mp3 from lossless hi res audio files, you will of course dispute this, but it doesn't make it so.lokyc said:For example the issue with hi res audio. The recent thread on the Meyer/Moran posted a more up to date paper which disputed M&M's findings. As for Meridian, they have recently changed their mind. The issue isn't frequency and loudness, but time domain.
A lot of research is still being poured into psychoaccoustics and how we perceive sound. That is next exciting development. And only when we fully understand psychoaccoustics can we develop the tools and measurements to quantify it.
The only thing an amp does is take a small signal and make it a big signal which can move some woofers. It should be faithful to the input and no more. A good amp will add nothing, many good amps add nothing, they all *sound* the same. I propose that you would be unable to distinguish two amps from one an other, provided they measure well, are level matched and not clipping. You will dispute this but it doesn't make it so.As for the comment all amps, if they provide the same response etc etc will sound the same regardless of topology.
Duh! That's completely not understanding hi fi in the first place. Clue; its in the name. High Fidelity. Fidelity: faithful to original.
Does it, can you hear it, are you able to measure it, are you sure you're not just repeating long dead HiFi mantra?Every stage in sound reproduction introduces distortion. In the words of John Bowers, the best system takes away the least.
Yes.Different topology tries to achieve the same thing with different methods. Size, efficiency, etc. If two amps can output exactly the same way, good on them. They just chose different ways of getting around real world constraints like hysteresis of capacitors, transistor distortion, electrical noise etc.
The author and article are spot on. You seem to have gotten confused.I could go on. But this article while is right to challenge the snakeoil touted around, unfortunately falls short by overgeneralisation and banality.
I think you're missing the fundamental point of the article, which is that no-one can tell the difference between various amp manufacturers, high-res vs standard audio, expensive vs cheap cables etc.
And giving good reviews to whoever advertises with them, even if the reviews have to be ridiculous while they are at it. I sometimes wonder why the magazines cost money to buy the amount of adverts in them!They are dealers making money from addicts. It's all about the serotonin.
Regarding cables and the like, this is true , such items are pure fraud. No doubt about it.I think you're missing the fundamental point of the article, which is that no-one can tell the difference between various amp manufacturers, high-res vs standard audio, expensive vs cheap cables etc.
I'll retract that statement for amps then, and rephrase it as generally people can't tell the difference. For high-res vs standard audio I would have to see the evidence of individuals consistently detecting the difference under double-blind tests to believe it.Regarding amps , high res vs standard , this is not true at all.
If you read the AES papers properly and look at the data breakdowns where available you will see that there are always individuals that get either 100% or a statistically significant result.
What these papers claim from the overall results is that " on average" and as a a group , the people under test couldnt tell the difference!
That is a hugely important difference here , in no case does any paper say that no one can tell the difference and it is very wrong to take from them that they do say that!
I went to a show where Naim were demonstrating and they did a test to see if the room full of people could tell which was high res or not. He played the first 30 seconds of one track three or four times and nobody could seem to definitely tell between the high res and the CD quality version. The room was about 50/50 with each one and I don't think anybody got them all right. Not exactly scientific but still worth sharing I think.I'll retract that statement for amps then, and rephrase it as generally people can't tell the difference.
