Having stated - or at least strongly implied - that my kb 'satisfies my needs', I feel I want to respond (although I do not THINK that trident was referring to me directly) ...
Isn't a kb the "satisfies ones own needs" what we ALL are looking for? ... Even if two people purchase the same kb, they could be doing it for different reasons - but reasons that satisfy each one's own needs ...
and as far as kb sounds go that is SUCH a subjective argument ... some kbs may have sounds that are better than others, but if the person who purchased it is satisfied, who has the right to tell them they are wrong??? ... let's face it, if a 'gigging' musician purchases a kb that sounds like crap, he is not going to be gigging for long ...
I think that there are very few times a person can be told that that they made a mistake with their choice of kb: if they purchased a kb for a certain reason and it does not have that functionality; or if they purchased a kb for a far greater price then what they should have; or some reason similar to that ...

If one is evaluating the overall sound and balance of a person's performance, then I believe performers should definitely listen to what other performers are saying ...
As far as suggestions for other subjects, such as set-up, I agree that there are a lot of experienced players here who can offer solid advice ... but again, if someone's set up works for THEM, so be it ... and if that stops the discussion with that particular person, that does not prevent the discussion from continuing - as we have seen on threads from time to time ...

Personally, I would welcome suggestions after I have posted a song ... anything that would help me 'polish up my act' is appreciated - of course other than a suggestion to quit playing music -

In a nutshell, I guess I am saying that (to paraphrase) "one person's trash, is another's rose", and while we can - and perhaps SHOULD - offer an OPINION, it should be presented and accepted as just that - another person's OPINION ...
