Does mfg's name/model affect your opinion of sound

If there is any science to our hobby, and a designer is looking to address any deficiencies he feels are there, then you would think that components from a single manufacturer would have a similar sound, a "house sound" if you will. If they all sounded different, you would wonder what the designer's criteria was, or is it just random thoughts and lets see what happens. I would be suspect of such products. A manufacturer should put his sound where his mouth is.

Well, here is a perfect example:

A happy Listener sits smiling in front of that System, holding a CD Box in his
hand ---> obviously he likes it very much

I was whining after reading these lines ( I am sensitive you know)

Now, let's go to Reality:
When we look at that picture we can see that the Preamp Display shows
"Phono Direct"
"Vol. 80.0"

But that is not all
On top of the Rack there is a Turntable with a Tonearm
but there is no cartridge to be seen (only the wires coming out from the Arm)

That's High End today :-)

So, startup company "A" designs and builds a preamp that exceeds all expectations. In fact, it practically becomes an instant legend. Over the years, the company produces a dozen other preamp models. By now, the first preamp has become a verified classic, but what about all those other models?

Are we to expect a given company to supersede the piece that made it famous? If so, how many times? How long is it before a brand becomes larger than life? Even if sales remain high, is it a given that the company remains faithful to a business model that adheres to sequential improvement and value, even when the outside appearance of the product line appears to advance with time?

I don't believe there is a concrete answer. Companies tend to change over time. That change can be in any direction, better, worse, or just different.

I try to keep an open mind because today's new startup company may have just introduced tomorrow's preamp classic, but like everybody else I do have certain expectations from some brands out there.

Manufacturers only matter to me to the extent that there are certain expectations of quality levels based on a manufacturer's track record. I don't expect mediocre sound from ARC, Herron Audio or VPI nor do I expect that high level of performance from brands that have not attained anything near that in the past. IMO, it's a matter of setting standards and the target market segment for each manufacturer.
