No, your experiences are not fact. They are just that, your experiences. How do you know how much better your hearing is than average?

Heh...you're killing me here. What big name dude and theory based on old out of data tests are you referring to, pray tell? I am keeping an open mind, I'd just ask you to do the same.
I have never mentioned anything about math and physics fall behind the times, however the correlation between numbers, graphs and what we CAN and DO hear surely does. Seems you have a problem understanding this... your loss not mine.

MY experience are fact as I have successful blind tests behind me to support what I hear and not hear, yet another thing you seems to have problem understanding.

My hearing was tested by a Doctor two years ago and I hear 10dB better than the average human, according to the Dr.

Some guys are refering to "big names" and tests, I donīt care much about them or their names since their testing methods are old or done in the wrong manner. producing "false" and useless results.

You donīt need to ask me to have an open mind as I do allready have that since waaay back. Therefore itīs really funny for me to see how thickheaded some guys at this board are, going on with their "blah blah" when they donīt have a clue about what they are talking about.

Patriot V100 4MHz, 800V/uS
Zapsolute 1MHz
DynamicPrecision 800kHz, greater than 250V/uS

Spectral 600V/uS, this one Iīve not heard though.

And yes, these are audio amps, I usually use audio amps when listening to audio/music Do you have a better solution/suggestion?

.......At what frequency did the good Doctor indicate your hearing to be 'better than the average human being'?

.....And equally pertinently, what age of Human being did the good Doctor have in mind?

That's just it -- I'm not religious about the subject of audio. If it can't be backed up with science and math, it's not there as far as I'm concerned.

Would you have schools using textbooks claiming that the Earth is flat because some people believe it to be?
How stupid comments.

Before anyone managed to describe/proove with science and math that the earth was round and spinning around the sun, does that mean that the earth actually WAS flat and the sun was spinning around the earth ???

Neither life itself or magnetism can be described and explained by any scientist, does that mean we are not here??? Wake up please...

What many of us DO hear is actually there, soon we will have perfect methods to describe this in numbers and graphs, we are not fully there yet though as far as I understand.

...slew rate of 800V/uS...am i correct in assuming the amp. swings in excess of 6KV peak for this to be true, (i.e: 'audible')?
I think the numbers are -3dB full power bandwith up to 20k, Iīm not sure though. See my other post for "specīs" of some high resolution amps. If I remember correct Spectral has/had an amp with 5MHz BW.

The Patriot V100 has an slewrate of 800V/uS and is a 100W/8 ohm class A amp. I dont know where you get 6kV from.

Peter old chap.....what 'old theory' are you soooooo elequently aluding to? surely you are going to tell us....OH maestro?
surely your ears are not the much vaunted 'modern standards' at issue here..
Dear apprentice,
any old theory that contradicts my and MANY others findings about audibility of low level distortion in audio gear...

It was one of those test where you put on canīs, sit in a silent room, and then listens to sinewaves at various frequencies. Donīt remember exactly the "BW" of the test but could it have been 100Hz - 5k or something like that? At 5 or so fr. points.

About age, I donīt remember but the Dr was sure "impressed" and surprised, not me though, I knew I had good hearing

Hi Peter,
With agieng, it is to be expected that your (our) hearing sensitivity and bandwidth degrades, however the ear/brain system is self learning, and according to aural experiences can actully become more discriminating.

The more of, and better systems that you get to experience, the bigger and better the database of 'captured' sounds you will accumulate, and become an even better judge of systems.
Also be aware that one's sonic preferences may change during this period also.

These factors are ones that our younger bretheren seem not to understand.


Eric.

Talking Ah, the Halcros...

Sometime ago, I already said here, I listened to the Halcros (the amps and the preamp).
To me, they were playing very well, but the conditions were not optimal for the listening session.
Some people didn't interpret very well my words, because I never said it's the best.
But it has an impressive soundstage (large and deeep).
I would really like to hear to them in my room.
People (and the manufacturer) say they are the finest amp ever made.
I don't believe in that.
You had to listen to every amp in the world, and then you could say what's best.
As I don't believe specs are everything (they are just an initial indication), just by reading a paper I would not say it's the best.
It could have the best spects, just that.
But I would have to hear it, and all the others.
Of course, that's impossible.
So... the rest is marketing.

Talking where's the graph

Hey Peter,

Did the doctor print a graph?
Did he give it to you?
What's your frequency responce at +/- 3db?
And THD?
And S/N ratio?
Sensitivity?
Selectivity?
Channel separation?
Ahhhh... forget it, I'm just joking.
