Throwing 2 High End brands together will not automatically equal success. Thoughts?

Randomly throwing two high end brands together is irresponsible and very unlikely to be cost effective. Different house sounds are very different, and often not complimentary. The only point to going to a dealer is to gain knowledge and guidance in your choice of components. Not helping you make a synergistic choice is unconscionable. 

I suppose it all depends upon a dealer’s customer base. I once ran into a high-end home theater installer in the Sacramento area who characterized his customers as simultaneously having the money for very expansive gear but poor listening skills/aural awareness. He apparently did quite well, financially, but expressed frustration that the gear was not really appreciated. It served mostly as "bling" to show off. I don’t recall which lines he carried. 

Why a dealer would make a habit of poor synergy if attempting to sell to experienced audiophiles doesn’t make any sense to me. It seems self-defeating in the long run. But then, I’m neither a businessman nor someone who buys gear in dealer showrooms.  As far as I’m concerned the only sensible pace to demo gear is in one’s own listening space. 

I don't get a dealer doing this unless they are poor listeners. In early days  relied on dealers and shows to gain an understanding of synergy between components. Over time, as I came to understand my preferences and/or my unique needs for my system I made my own choices.

Agree. It doesn't.
