Default mbl resistors upgrade

Dear friends
I own mbl gear consist of monoblocs power amps 9007
Pre 6010D
Dac 1611F
As time goes by i understand that hi end meaning design
But ulta hi end meaning design and hi quality parts
I wish to change all my resistors in my equipment by
Non magnetic resistors which i know that by doing so i will
Achieve much better sound.
I know that there are many types of resistors and i don't know
Which type is best for each section.
I have added pictures

That you all for your help

You know about resistors.

You don't know about resistors.

I suspect that is where your confusion lies. 'Hi end' can mean good design or just good story. Ultra high end always means good story and expensive parts, which often may be inferior to normal parts.

I don't know what do you mean when you say good
Each are less than 0.50$
A lots of manufacturer don't understand that magnetic
Parts are don't suit to audio
Good you mean like Panasonic Fc ?
I think that in this price tag they could install at least
Panasonic Fm.
All i know that as time goes by mbl getting more and more
Commercial, for example all mbl in the past uses
Mu metal cans for the transformers, now they don't.
In the past they were using rifa PHE200 and now just cheap
China caps.
Good ? What does it means ?
Any way in this tread i am asking for help to know if any one
Did such a change and what was the exact result
In which resistor model was used.
For the small ones i was thinking dale RN60
For the bigger one i really don't know.

RN60? An acquired taste and one which i fail to acquire. The originals are what? Rhoedenstein?

Not sure if any sensible voicing will come out of random resistor/capacitor changes. One should have a pretty good idea what each resistor/capacitor type sounds like and in what direction they would like to change the sound.

Good results may be obtained by just replacing key position resistors: input loading and nfb.

But what is the purpose? Different tonality? More resolution?

I wouldn't say different tonality.
I bought mbl gear since i love it's tonality.
However the goal is to achive greater transparency and more resolution.
I have been playing around with some magnetic and non magnetic parts.
The differences was very noticeable by transparency and sound stage.
Ever more in my monos i have replaced the big caps by epcos screw in caps.
The sound was better than the original. But when i have replaced the screws
From ferro screws (the originals that comes with the epcos) to brass
The sound became even better mainly in the bass/upper bass section
Grand piano sounding like wow bass notes move the air and it's filling the room.
I don't know what is the brand of my resistors today but as i said before
Audio manufacturer do not understand that non magnetic parts is a must in audio products.
So i was thinking to replace the small ones to RN60 but the bigger ones i still don't know.
Ever more regarding to the small resistors how do I know what is the wattage of them?

The wattage seems unimportant for the low signal stages. Anything above 300mW should do just fine. As for non magnetic i seem to like old style Holco and Shinkoh. The Shinkoh are available 0.5W, 1W and 2W if you can find them.

Usually the only difference is the price-tag... my 2cents.
