My post was talking about the X32 Core vrs M32C, not other models that actually have preamps. I can not see how the M32C version could possibly sound much different. There is nothing there that IS different to make it sound different, except the front panel, which last I knew makes no sound. I would expect the Pro mic pre's on an M32 console would sound better, I have however read several reports that say the sound is not so much better that it makes a gigantic difference. There are other things on the M32 consoles that do still make them more desirable, probably the improved pro faders being the biggest of those. Also, lets not forget which desk came first such that it's features and firmware capabilities could be adjusted upward for future models to benefit. I think the X32 was around well over a year before the M32 ever hit the market. That made a lot of 'beta' testers out there to help perfect the M series debut.
