Yes for MM absolutely agree - would be nice.
But, a modern opamp you close enough on MC and for the MM use BF862, of which there are a few good designs that parallel them - Syn08 comes to mind, Denis Colin's approach could also be developed a bit - he used LSK389 in front of an AD797

Ah, but the thing is to reproduce the bite of that sound in the home! The sense of a Marshall fired up, ready to do battle, a few feet away from you, the guitarist just lightly brushes against his axe - and all sorts of high intensity scrapes, farts, whistles, audio doodlings escape from the maw of the beast, it's like a caged cat, ready to pounce ...
The sheer, grab you by the guts, rawness of that sound is what you want to be able to reproduce ...

It is a very well known brand and I dont want to make people think they should buy something else as I dont know if there are others which are similar.

In which position in circuit? I know that you use DC servo in all your designs.
PMA, like the rest of us here, is a 'rank amateur'
There is a difference in opinion and attitude. I think politeness could be honored irrespectively of opinion. I have seen lack of the former at times towards JC. Bad form, and reflects negatively on the sender.

I would call polar cap between opamp lazy saw that alot in 80's and 90's mix boards.
Films where too physical big and priced higher. No servos and no trimming lazy . They need more R+D in soing it dc coupled. The purpose as I was yold was to keep dc off the switches.
I did not find Ackermanns thesis on the web but i found this :God is in the Nuances | Stereophile.com
Here Markus Sauer made some refferences to the Ackermann research.
Markus is a friend of mine and i can ask him if he knows how to get the paper.
I also know that Ackermanns results where discussed here in germany in several magazines some years ago.

Any controls? Any check for skew of spectral energy? I might tire of sitting 3' in front of a string quartet for 159 performances of the same piece.
For me, if earplugs are required it's junk sound - heard enough of that to never want to get close to it again ... and you don't need concerts to get that, the stage production of Phantom of the Opera I saw was largely ruined by a grubby PA that went into semi-meltdown on every big note.That's what concerts and earplugs are for.
Typical concert sound is not grab you in the guts, it's far closer to having thick porridge fired from a high pressure hose into your ear drum - for some strange reason this doesn't turn me on ...
Nice find ... just started reading it, like this bit:
I find quite peculiar those systems which are supposedly 'hyper-revealing' - like the chap who turns a 1,000 watt spotlight onto his girlfriend's face and then inspects every pore of her skin from a distance of 2 inches - hmmm, when did I say you were beautiful ...
But ultimately doesn't go anywhere useful - same, tired, old thinking; no answers here ...
