High-end amplifier clarification?


At what point do you consider an amplifier high-end? And, why? What is a good example of a non-high end amp that just misses being high-end? Also, what is an example of an amplifier that just makes it into your high-end rankings?

Weseixas, some of the best speakers I have heard are much more than 4 ohms.

Just so you know, our amps can do a 20 Hz square wave with no measurable square wave tilt, which will not be the case with an amplifier that cuts off at 10Hz.

The point of this thread I thought was all about what made an amplifier high end. To that regard, I hate to say it but its a simple fact that the intention of the designer is what fulfills this definition, not the actual sound produced! Now you are welcome to your opinion, but I think as you look at this subject, in due time you will see that a certain ability in an amplifier is not sufficient to call it high end without other factors.

Now you say I am defending my topology, and there is some truth in that, but at the same time I am also defending others, for example those that were on my list in my last post. In each case, a high end amplifier manufacturer was named, but their 2 ohms response is likely limited.

Now I realize that the whole Voltage/Power paradigm thing is a problem for you. I used the term 'paradigm' for a reason: A paradigm exists when anything outside that platform of thought is simply discounted as 'not right', 'bogus', 'non existent', 'pseudo science', etc.

Now I think you have also brought up a different subject, which is 'what is the State of the Art (SOTA)' which is a different question from 'what is high end?' We can easily see that there is a difference- if the manufacturer of your amplifier has another model that is built with similar ideals, are you going to tell me one is high end and the other is not?

It may be as well a question that is equally difficult to answer- it took me 15-20 years to have a really good answer to the issue of high end.

But I can say this: what would define State of the Art? The ability to drive 2 ohms? In the absence of the ability to also sound like real music, the answer there is no. IOW, the ability to sound like real music has got to be in the cards, because it is the music that it is all about.

Now if you could build an amplifier that was a voltage source, that was also lacking in the odd ordered harmonics that color such amplifiers, I would be down with that in a heartbeat. I don't like brightness- to me its a more sinful coloration than the traditional 'tube' sound (by that I mean the 2nd harmonic, which BTW is lacking in our gear as it is fully differential). So there are aspects of this that seem to point at taste.

LOL, Ralph, i guess that response will do..... I accept :)

The best speakers made are lower than 8 ohms and this is absolutely true for a SOTA speaker system, if low distortion and low dynamic compression is the goal.

I would not be interested in an amplifier that is not a true voltage source or at least close to, too much of a compromise to begin with IMO and i will agree that in itself does not make an amplifier hi-end, just not SOTA.

Maybe we should define a price point , i will give this ago, any SS Amp over 10K should be a voltage source amplfier IMO.

Betta ?

Atmasphere,

Where can i find bench test results of your amplifiers? Most tubies have issues with a 20 hz square wave due to there trannies, so it would be interesting to see what yours look like without.

Do you post on your web site ? I last heard one of your amplifiers at Stereophile 94, we were on the same floor, so i guess a ton has been done since, well apart from the Hi-end renumeration... :)

Will you be in Atlanta ?

Regards,
might try that Nagra pyramid amp for it aerodynamics. Any idea what it weighs. Had tubes but I burned my face real bad when I got bumped at the lake.
I prefer to look at measurements, scopes, and articles (I don't understand ALL the technical stuff but, thankfully, there are a lot of real smart people that do) about amps instead of dealing with reproduction of sound by some lame "musician"...a high end amp is simply a better and more expensive thing than otherwise, and putting music through it can only cause ear damage and incite sometimes shouted "opinions" from less worthy so-called "other people", and that can only lead to strife and discomfort. Art? I mean really...who cares?
