Nice to have a special forum for a amplifierbrand. It will create a solid base of followersFirst of all I´m not a technician or audiodesigner. Just a customer of highend audiogear for the last 20 years.Had the privilige to own several poweramplifier designs from Colangelo (ML-3), Agostino (KSA-100, KMA-200´s), Jeff Rowland (model 7 Series II, IV and model 8T) and Nelson Pass (S/300 and S/1000´s).

Let me guess.. your a self proclaimed authority on amplifiers based on the fact you have owned some of the higher end amplifiers? This must be the case.
Class A has no place in your life ..based on the fact that they consume more power? You unfortunately cannot tell any audible differences because you lack the knowledge to remotely know what to listen for.
If I were to make a guess I would rank you among the thousands of people that ask a salesman what to buy based on price and status.
Do not consider yourself a serious audiophile because your not.

You all have legitimate opinions. Your own is no better, except to you. Move on with no further accusations, insults or finger pointing.
But you do I bet!
Nice to be able to reach a conclusion based on so little information. Would love to have such a simple structured world.
Let's say Class A is king, satisfied?
Mr Eno,
less than a week ago you strolled into a cave, filled to the max with individuals who have been building/listening/learning about Class A and in particular Pass lab circuits for several years on end.
Some (re)discovered Class A amping not so long ago, others have never left the dinausor cave.
The majority here spends a great percentage of leisure time on studying amplifier circuit schematics, datasheets, following tech discussions, looking for component sources.
After investing a good deal of time and money in a project, one is bound to be proud of each newborn.
Most here regard Nelson Pass as the most innovative audio designer.
Let me suggest you walk into a hunting lodge, stacked with fellas carrying automatic rifles with laser vision, and you'll tell them their dinausor bow and arrows are fossils and un-ethical in an ecology sense.

Dear Mr. Vermeulen,
Thank you for your eloquent response and well ment advice.
First I did not introduce the concept of the dinosaur as metaphor for Class A designs, that was Mr. Grey. I only questioned the concept in the light of historical and contemporary amplifiying achievements
Second I have the highest regard for enthousiastic people who devote large parts of their precious available time in constructing amplifiying devices based on the designs of Nelson Pass.
Third: Sure I understand that most of the those enthousiastic DIY people on a forum that is devoted on the offspring of one particularly designer find he's their inspirator. But doesn't mean even his work could be open for scrutinizing without offending the person in anyway. As I recall he wasn't and he found that my questions were legitimate.
Fourth: I'm not on a ecological bandwagon, that was never my perspective but a conclusion drawn by others.
It seems to me neither one of us is a cavedweller nore any other individual on this forum as far I can *****. Apparently we differ on some things concerning amplifiying matters but maybe I underestimated the effect of disputing a subject that represents one of the "core-values" of this forum.
As Nelson Pass already concluded in this thread:
Apparantly your all in sync that Class A is the way to go so there's no need to question the merit of that concept for the design of poweramplifiers. There are, according to Nelson Pass, other more efficient ways to cut energy-wasting then denie yourself the best technology available to mankind when it comes to drive a loudspeakersystem.
Seems to me the me a pretty definitive end of this discussion.
Thanks for your reply and other witty contributions I at least enjoyed, to this thread.
class a performance at less Iqc ?
It looks like everyone agrees why we would use Class A. The
issue is to waste less power. There are some good avenues
for this that don't require any re-design of products
you grabbed my attention, how?

Re: class a performance at less Iqc ?
Nelson is probably using these methods in his current line of class-A amplifiers. I'm not sure it would be fair to expect him to reveal this in his current range of products (would it 🙂)?

Re: Re: class a performance at less Iqc ?
Sure, it would be fair for him to reveal he is using such a proprietary method in his current products... The details of such a method he might not want to discuss though 😀Cloth Ears said:
energy in class A
Energy is always an interesting subject regarding Audio:
My mother at times use to call me a bottom less pit of worthless information so I will share some:
1. My new Plasma television uses 500 plus watts when turned on.
Best to turn it off if you are not in the vicinity. This is more than most Pass amps at idle.
2. The typical car engine is only 28% efficient the rest gets lost in heat and mechanical losses.
3. According to most quantam (sp?) theory -- The human body has enough potential energy as a 40 megaton hydrogen bomb, we just can't figure out how to use it. Come on fusion. dave

I have uploaded the specific brochure to www.passlabs.com/np
There are 6 pages entitled "Stasis 123 Bro"
By the way, the hyperbolic description came from Rene.
