How do you know I have not used one? Have you any idea how much gear I have used? How much gear I have forgotten about? I don't remeber off hand how to reassign the VCA names on
a Midas Heritage 3000. Does that mean I have not used it? I run a pro audio company and work in countless different venues doing sound for countless different bands. I run across TONS of different pieces of gear. I always make it perfectly clear if I comment on a piece of equipment second hand without actual experience with it.
Also, I never said or implied that the M12 was a "toy". You mentioned how much cheaper the M12 was. I was merely pointing out some reasons why the Allen Heath is more expensive less someone think that they were the same in feature, but different in price. Having 4 band EQ instead of three band can be a huge advantage. Having 6 auxes instead of 4 can also be a huge advantage. I agree that the FX are pretty cheezy, but at least they are there should it be your only option and need them. personally, I am not sure just how "unmatched in it's class" the Soundcraft stuff is. I am not a Mackie fan, but the ne Onyx stuff also sounds pretty darned good for what you pay. As far as 100mm faders, I certainly prefer them over 60mm, but that is not a deal breaker for me. They do however cost a little more. The Midas Venice has 60mm faders. If you want to talk about a mixer that is truly unmatched in its class, the Midas Venice is definately that. In fact, I prefer the sound of a $4000 Midas Venice over the $45000 Soundcraft Series 5. No doubt the Series 5 has WAY more options on it (more comprehensive EQ, dual inputs, split outs, VCA's, more busses, matrixing, more auxes, etc....), but the Venice just has a better sound in my opinion.
Comparing a Soundcraft M12 to a Mix Wiz is in the ball park, but certainly not a real apples to apples comparison. Also keep in mind that I was not the one who originally threw out the Mix Wiz as an option
I have to sya though, yur last post would have convinced me to buy the Mix Wiz over the Soundcraft. And here in the states a Mix Wiz can be had for just over $900 USD, which looks like it may be a different ratio than over in the UK
