Damned brands or not good electronics?

I posted a similar thread at the speakers category, I said that when you read reviews posted on Internet or magzines, you can read about what seems extraordinaries brands with no less excellents electronics, but the reality is that practically nobody knows, owns, sells or seems that has heard them.
This is a business game, and logically I think that all the dealers are looking for the best product, incluiding thats ones that are really expensives, because they know that always are people who can afford them.
Looking at the electronics department, there are brands that practically you can´t hear at any dealer:

VITUS
VIOLA
MESSENGER PREAMP
TRON SYREN PREAMP
REYAUDIO, that some people says is the best electronics in the world????????????
WYETCH
EMOTIVE AUDIO EPIPHANIA PREAMP
BLADELIUS
TOM EVANS
FM

WHO OWNS OR HAS HEARD ONE PIECE FROM THESE BRANDS?

You can says that these brands are expensives, but sorry what happens with others brands, that, SURE, you can´t say that they are EXPENSIVES, that many people and magazines says that are fantastic, with great price/quality relation, that sounds as brands that cost many times(x4 or 5).....but they are not growing as seems that they must to do:
SAS
MARSH
IRD
DEHAVILLAND
DEJA VU
EASTERN ELECTRIC
MOSCODE

WHO HAS OWNED ONE PIECE FROM THESE BRANDS AND HAS SOLD THEM AND ALMOST WHY?

Perhaps these inexpensives brands are not so good as they want that we believe? or their reability, due to a poor construction and components employed , is bad?

Peace for all.
