My friends... blind followers of this Audio Guru

Hello:
I have 2 friends that are "very hooked" on this audiophile thing.
They have been guided by this "sound guru" wich he has the representation of Kimber, Audioresarch, ProAC and other brands here in Mexico.
He is a well knowed guy in this thing with years of experience.
They have spent lots of $ just making upgardes, advised by him!

Lets put the example of one of them:

First started with:
Bryston: amp pream, now he switched to Audio research
B&W signature series sold them and now waiting for ProAC
CD: Had a Meridian, now he has a CD3 Audio research.
Cables inteconnect: he has upgraded lots of times! Kimber only: hero, tonic, KCAG finally he is with the Kimber Select 1030
Speaker wire, from kimber 4PR to 8TC
Power Kord: PK 10 Gold

Yes I know, lots of upgrades
But why not getting all the stuff once? or most of it once?

Is this normal? making upgrades grdually of the entire system?

Everytime we talk about audio, they threw lowballs on other brands that are not the ones recomened by the guru
they always say:
The guru says: Audio research is the best, the other brands NO, get away from them

Regarding inteconnects wich has been the debate theme, with tests over and over and over and over!! like
with this one you can hear a little bit more soundstage, with but little harsh etc etc.... tests like that
Finally they say "All the other brands are not worth"
If you are going to spend your money the cable to get is "kimber Select" if its not Kimber select, get the usual kimber but dont purchase other brand.

Like 7 months ago, I purchased a power kord from Mr Cable, Super Flex,10 gauge power cord
They laughed at me and told that was a horrible thing, one even didnt allowed to test it in his system because it was not Kimber and was ugly.

My sytem is not top of the line, but aIm happy with it
You can see it here, just search mexico.
Sometimes they make me laugh, or doubt, just becuase this guys says it
Yes I know there is a great debate of this, but they are the only ones spending over and over.

We dont have in here lots of brands, only a couple.

What do you think of them?
