If you look at the pictures, it's not that many components. The schematics can be a little bit scaring but the electrical performance is astonishing and I'm sure the musical performance also is good.

The feedback network is smart but I think a DC-servo is better. Then you have no signal at all through a rather big capacitor. It's better though to have 1 µF plastic than a 100-1000µF electrolythic.

Ha ha ha ha ha...... I'm sorry I could help myself. Often times the more complicated a circuit is and the lower the static distotion numbers are the worse it sounds. Go look at some of the well reviewed designs and you see very simple signal paths. The simpler circuits from Nelson Pass sound better than the earlier designs that measure better.

Servos.
So you want to trade one good film cap for the same good film cap inside the feed back loop of a high gain op amp integrator with another set of supplies for the servo and the interaction of the servo amp with the origional amp circuit. And this will sound better..... Why?

1 µF plastic than a 100-1000µF electrolytic.
Depends on the film cap and the electrolytic. Any one want to put a Wima up against a Black Gate electrolytic?

I'm more in the game to design and then try to make comparations (right?) between different items. It's very hard to switch pickup for instance but it's rather easy to switch between CD and external DAC. It's harder to switch between amps if you don't have the right gear. I would say there are very small differencies between good amps, not as big as some people claim.

How many components are there from the digital signal to the analogue output of a CD-player, not a few I would say. It's not the amount of parts that counts, it's how it's done.

Some people thinks, many parts -> I don't understand it -> can't be good.

It's not wrong to design a simple but smart solution but it's wrong to say that a bad solution is good, simple because it's simple.

I will also point out that a slow DC-servo has very little influence on the sound quality, only if it's designed well.

Anyway, I'm very interested in the design idea from the japanese guy.

Ha ha ha ha ha ha ha ha ha ............. I beg to to differ. Go and listen to some more amps. Maybe your definition of good needs redefining.

I would say Krell and Mark Levinson amp are quite alright despite the amount of components.

I suggest we end this debate here. We are now talking about taste and taste it's hard to discuss.

These kinds of discussions always remind me of the
wine business. In the industry there are two polarities:
those who believe you can precisely define a wine through
spectrographic analysis on its constituent compounds, and
those who insist on tasting small but finite differences and
describing them subjectively. Even much of the descriptive
language used is the same.

Among the consumers, you encounter:

A) No taste & don't care

B) No taste but lots of money

C) DIYers

I agree to stop if you will, your humorous statements are making my sides hurt from laughing so hard. You know how they feel about humour on this forum. Go build one of the Nelson Pass designs and listen and see if you are still so fond of "parts farm"
designs.

Speaking of wine..

If you are into good wine ... Try out an wine called "Touriga Nacional" from "Herdade DO Esporăo"..

Thats really good wine at a price of ~10$ in denmark .. I have heard that in their country this wine is more expensive..

We get only about 200 pcs. to denmark and they bottle a total of ~32000 pcs of 1/2 litre bottles....

This is worth a try!! Even the boobles are darkred! Smells and tastes good!
