if you get better results with a different tool, use the tool that you get the best results from. just because people doing work that means millions and millions of dollars are happy, doesn't mean that you have to be. i don't think this is a problem. personally, i don't think that the Cubase mixer sounds that great, but i do know engineers that get fantastic results using it. i prefer the Scope mixer, but my opinion isn't everything. i did have a #1 recording(in Utah! whoopee!!!), so i guess the mixer's good enough.
what is this all being played back on, in the long run? if it's just your system, and no one else will ever hear it, then hey, it's your money, do whachoolike. if it's going out to the public and will be on mp3s and cds and wavefile downloads, then it REALLY doesn't matter that much. very few have systems that will properly reproduce extra high end. in fact, the extra high end, if it is reproduced at all will be distorted and shrill. still, "musicians" are rarely scientific engineers. they're suckers for marketing. for a while, all the asshole manufacturers(Mackie?) were putting "air" buttons and the like on their mixers because it makes things "sound better". really, adding high end to something that sounds like paper to begin with will fool the casual listener for a while, until their ears become used to it. then they can't understand why their music is so hard to listen to for long periods of time. too much high end=ear fatigue. i purposely cut high end off of things. very little material requires anything above 12-15k. most people have hearing loss that makes stuff over that point silent anyway and those that hear sounds above that point usually have a fear of high end in recordings that were mixed by "musicians" with hearing loss who compensate by adding extra. you're fortunate to still hear stuff up there.
i really don't care that much. actually, i hear all the time about how great the stm2448 and 4896 mixers sound(from real working musicians and engineers, not only guys in their bedroom). i also think they sound great just as they are, myself. my opinion isn't everything, though. in your world, i can easily be wrong, and there's nothing bad about that.
anyway, you like vdat, but hate the mixers. that's fine! use what you like. get the SDK and design your own mixer that responds exactly the way you like!
well, there's another one.
really. All the mayor pro guys out there would say exactly this. I now tend to be very careful about what I do from the beginning and on, so everything sits right from the start, instate of trying to fix it on the mix.
