Are these damned brands or not good speakers?

When you surf on Internet you can read about speakers as the Escalante Pinyon, Ultimate monitor,SP technology Time piece 2.1, Harmonic precision Caravelle, Lipinsky L 707, Peak consult Princess, Green mountain....all seems that are extraordinaries speakers, but the reality is that it seems that nobody sells these brands, nobody owns these speakers and practically nobody has heard them; perhaps the problem is that they are TOO much EXPENSIVES for what you get?.
I will be glad to know your opinion about all these speakers. Thanks.
