Didn't it occur to anyone that it is foolish to hard wire quality pres into a mediocre mixer. You may as well keep the pres and the mixer seperate, bypass the internal pres and someway, upgrade the mixer or, considering the way things are going, you may even lose the mixer altogether and opt for a control surface, independent pres and an indpendent monitor section.
There are most certainly mixers with better component parts than what Soundcraft has to offer. The issue is cost. Those companies manufacturing affordable gear make the choices they do so that their equipment will be functional on a certain level and affordable on yet another level.
Why not make a kit that turns a Behringer mixer into an SSL. I don't mean this as a joke either. Obviously, the difference is not the concept bu the components. Therefore, take your Behringer, improve all the components with SSL parts and components and viola! But, clearly, it is not that simple.
The same question could be put to the music. For instance, how come two guys playing identical guitars, one with and identical bass and a drummer with identical drums in the same studio as the Beatles don't sound like the Beatles. This is rather extreme but the point is, the whole is often greater than the sum of the parts. Therefore, merely sticking better parts, like taking a mediocre group and adding a great drummer, will certainly be an improvment but it will still be what it is.
Not only that but, when the pre amps are left free standing, you have the choice to change them, add new and different colors by mixing and blending differenty types of pres. That is a wonderful thing.
I therefore conclude that you should make a companty the manufactures a mixer that has bussing, faders, a monitor section and inputs and outputs but no pre amps. This device will have a seperate bussing or plug-in section for the pre-amps and you can route any channle to any preamp however. This could be the same as having built in pres but where the preamp would go, all you need is connectors. Plug in the preamp of your choice and, bang, your good to go. You could also make this thing kinda work like a control surface too. I suppose there might be some matching problems and possibly some noise problems but I am not a techy and don't know if that is so or if such problems could be dealt with. I do know that such a device would seem to serve the home recording market well.
