Mixing and Matching Cable Brands: Bad Idea??

I'm a French-Canadian descendent who drives a Japanese car made in Indiana with German tires rolling on American asphalt, powered by fuel imported from only (Dutch) Shell-knows-where!
Then I bought a German car with French snow tires that was otherwise really terrific. So I put on exotic Japanese tires that are a bit disappointing. Must I really get German tires and move to Berlin, or is wearing a TAG-Heurer enough?

I try to keep it simple. Granted, I have a different amp, pre-amp and front end. But I have eliminated for the most part as many other variables as my brain and my wallet will allow. All the speaker wire is the same thru-out even internal to my speakers and crossovers. All signal wire is the same thru-out my amp and pre-amp. Much of the signal wire in my transport and dac are the same as my amp and pre-amp. All the connectors on my amp,preamp cd and dac are the same. All the new wire and connectors when replaced were soldered in place with the same material. Replaced the so called isolation racks and high mass platforms with Sistrum technology thru-out. It becomes a complex procedure to keep it so simple. I feel my system sings as if it were a quartet instead of the childrens choir at the local place of worship. Tom

i think that this is all about matching cables and components.
thus there is no advantage for one brand only.

especially if we're talking about not netural (aka VDH) or very revealing (aka XLO or silver made) cables - if you take them all the path - you'll get too much of revealing or "color".

so, i'm totally OK with "mixing".

Eur how can you say which cable is not neutral or is, revealing? Have you ever heard a system you new well that was wired thru-out with any of the two cable brands you mentioned? I haven't.. If you haven't either then can you assume it was not interaction of the various cables placed at random locations thru-out the system..Tom
