This is what I'm slowly finding to be the case.
Essentially going back to theory and it's working out in practice is that, the higher the input impedance you can get the better.
i see what someone is saying about the signal potentially being too hot but I got back a DI from another person and ran it through my setup and this sounded as expected, pretty awesome. However! His signal was orders of magnitude louder than mine. With mine around --30 - -22db his was printed around an average of say -8 - -10db, so a much hotter signal yet his still sounded cleaer, less top end, much more rounded and FAR more where it should be.
Now whilst that might sound simple to get more impedance, it seems most higher end equipment still tops out around 1Mohm, and guitar from my calcs seem to want at least a minimum of 2mohm (tbh this all comes down to how hot the pickup is, proximity to the strings as well etc etc and 2mohm can just be the starting point), but fundamentally it means I had to dig out something which when I checked the tech specs, 4.7mohm on it's rear input - what do ya know, a marked improvement in the tone. It's being coloured on the way in with this preamp, so it's a prompt to look for any recommendations on a high impedance DI if anyone has one? As clean as possible.
As an aside the pre's might sound "cold" but that's actually the beauty of clean Midas pre's they don't colour the sound so we know what on earth is going on.
I want to thank those who helped it was much appreciated, and whilst it definitely CAN be input level, it's very much a contributing factor it seems. I mean unless someone wants to tell me it's all wrong and explain some theory but the sound is telling me otherwise.
