The biggest 'secret' is 'elegant simplicity'. Try it folks, tends to sound better than complex circuits.
... mmm, that's the rumour around here but simple circuits may also have a simple performance and complex solutions may not add anything. Life is more complicated than that, Mr. Curl.john curl said:
But this simplicity needs another requirement. This simplicity needs very-very good supply rail. R1-R4-R23-R26 is connected from rail directly to gates. Very good rail regulators is a must here.
Mr. Curl, why don't you approach with cct that has high psrr that don't require very good supply rail? For example using ccs instead of R? May I ask what is the consideration?
I can't to tell, that Halcro amp is very simply... 😉 ... Also complicated circuit can be good " tuned " ... 😎
Simple circuit - simple distortion,
complex circuit - complex distortion...
which one does the ear prefer? 😎

Complex distortion ? It is superstition... You can make simply circuit with horrible distortion too...
Well, I succeeded to stir around in the pot a bit...
I wouldn't really claim my previous statement to be the truth, it's of course not that simple.
However I use to think lesser gain stages the signal has to pass through the simpler the harmonic spread look like in general, that's maybe more what I have in my mind with the previous statement.
Upupa,
when you say "horrible" I interpret that as a matter of quantity, not a matter of quality, thats not what I said in my previous post.
I can tell you and anyone else who think that Halcro alikes with ultra low distortion and super hig damping factor is the direction that there's more then meets the eyes!
Too many SS designers don't seem to know the physics of loudspeaker elements and how it behaves in conjunction with the amplifier.
While saying that I doesn't mean per automatic I favour simple designs with some kind of tailored pleasent distortion, unfortunately, both camps are more or less lost I would say in this battle, again I say it's much more then meets the eyes, and I will not disclose here things so few unfortunately seem to know and have shown up here about SS designing as I have seen during the past 2 years here on Diya as no one takes up the real matter, sorry! I am going to just sit here and laugh! 😀 (I dont mean literally people are bad designers as I think there are several skilled designers here around, including even you Upupa!)
But, I am sorry Upupa & Co. but you have been too long in wrong direction, while Upupa is right in his critics to many simple and weak designs shown up here on Diya, I don't every now and then hack down on people with words like "horrible, "stoneage" etc., I still do in fact support to some extent his view, but not fully.
Elso,
I'm in, whats your IBAN? 😀
Cheers Michael
PS. And I wouldn't hesitate for a second dump a pair of Willson MAXX in the Marianer Grave if I was given a pair! 😎

folks:
read Mr. Curl's quote carefully. He didn't say "simplicity", he said "elegant simplicity".
not the same thing ...
Mr. Pass works along these lines also.
By the way, this has been an EXCELLENT thread😀
thanks to John for all the nuggets and thanks in particular to justcallmedad for the questions to help drive it along.

I just want to make a remark and I try not to be personal.
I am very disappointed with the discussion on this thread on the last 3 or 4 pages. Above all, I expect respected, "senior" members of this forum to contribute positively to technical discussions rather than making cheap rhetorics. My time is too precious to waste on reading such comments which has no useful contribution to the DIY Forum or any one interested in DIY Audio at all.
I hope people pay some respect to the Forum and contribute to technical discussions, based on facts and experiences. If you have too much time and just want to chat, or want to prove that you are smarter than the other people, I am sure there are much better websites on the internet for those purposes.
I thank John, Ricardo & Cegarou for their many interesting comments and positive contributions.
Best regards,
Patrick

It is neverending polemic, Michael... What is better, amp with really authentic sound ( which eventually show you deficiency of chain) or amp, which this thing mercifully varnish ? Personally I prefer first one, but mostly of people second...I had build many amps, from four transistor one, till much more complicated with tens transistors ones... And I'm constantly amazed, how some people recommend for own " child ", about which I know, that they are far from perfection, 'cos I had build many years ago something similar... I like JC's work very much from first time, when I saw it ( I like fullsymetric amps.... 😉 ), but I mean, that simplicity isn't " panacea "...

So why not open a new thread, publish your findings / inventions / experiences, and let people admire them openly, like they do for the work of John, Nelson, Hugh, etc.
It must be boring just commenting on other people"s design !!!

I mean this all quite sincerelly, Patrick... I don't like " run down " other's work, if you mean this thing... But I'm still surpraised by this big inertia in people's thinking - amp, which was " very well " thirty years ago, isn't the same now...
