And his MS20 line amp as I mentioned at Gearslutz - in the real MS20, there is a bass boost of sorts, and that's what you hear Should be noticeable from the demo I posted
Maybe a low shelf from the N**e 1073 can add some beef and fuzz, from the EQ and the transformers etc
Seriously consoles should not be subtle - I mean the difference between the Speck Xtramix mixer I had and going direct to my Lynx Hilo was night and day, even if the Xtramix is just a simple line mixer that was supposed to be clean, but it's not it sounds like "tape"
it may not be the most extensive test but a regular around here did audio examples of a load of the consoles and to me the difference was so marginal I decided not to bother...also I find Alex B audio demos to be too slight...
back in the day Consoles were designed to be transparent/accurate as possible with no coloration and to avoid any crosstalk. When designed well this is true and coloration is subtle.Some consoles do have a coloration but I'm sure at the time they were not trying to achieve that( even then it should be subtle , otherwise something maybe seriously wrong). Although some may argue that N**e did not have to put a transformer at every stage in their early consoles.
Most preamps in nebula can not be run properly because of timing/artifact issues(this is like running a limiter fast you get distortions),this is part of the reason I have not focused to much on doing many sample pres etc. So, does most of the coloration end up coming from this?! I think it's something that should be considered when using this stlyle of preset.basically a pre in nebula will run as fast as a compressor and if you go to fast you will get artifacts. You end up with a much more rounded sound in nebula than the hardware because things are havin to run slower.By the way scs treble bass runs different from the standard way of sampling a pre.
However i will say that missing the mixbus in your daw will have a drastic effect. Also nebula will sound different. One thing we cant do is put nebula post convertor.Try one channel through your daw mix bus to direct out of a single channel of your daw. This is the closest way I can check I'm getting exact results in nebula compared to hardware. Unfortunately it's still pre vs post convertor comparisons....
