I think your expectation of what you are going to hear based on what you've read on forums has a huge impact on the tone you hear.
I used to believe a lot of the common wisdom about "tone", but when I started seeing people who believe they hear a difference between power cables, I began to look at the whole thing with a huge amount of skepticism. Since I know now how colored people's experiences are based on what they expect to experience, I believe everyone far less.
As far as I know, no one has done any real scientific research on this subject, and until I see some sort of measurable data, I don't give people's opinions on the subject much weight. That's not to slight anyone here or this forum, because I think discussing gear is fun, but I realize now that the way I perceive nebulous concepts like "punchy" or "bright" is very different from that of other people, so I can't really trust that something that sounds "punchy" to someone else will sound punchy to me (or whatever).
Maybe this seems snarky, but people often discount the impact EQ has on your sound. A lot of people are into keeping the EQ flat, and I think this is part of why people stress so much about minute differences that some part on the bass might impart. If you know how to work an EQ, however, I think this obsession becomes moot. Want more high end? Don't worry about your fingerboard. Use your EQ!
