Then there is the ever present but not at NAMM Bob Lentini with S.A.C. and his SawStudio DIY rigs not for the uninitiated. For those unfamiliar with this concept a video.

Oh man, flashback time... I've had many discussions with an engineer who will swear up & down that no digital rig, live or studio, comes close to the sonic quality of SAC/SAW... his argument has always been that because the summing bus uses integer math instead of floating point, it's way more accurate.
Of course his argument hasn't changed in 20 years, while everything else has.
He's also a 9/11 Truther, FWIW
In a 32 bit world he is right on the precision of integer over 32 bit floating point as long as the summing bus values don't exceed 32bits. Did you ever ask him what he would do with all that precision when it comes down to a 24bit D/A converter? Oh 8 bits thrown away that were never needed or do we need a 32 bit D/A converter. The SAW/SAC is a digital studio/live mixer and the ancillary equipment to make this work has a lot more to do with the sonic quality (ie. mics, pre's and speakers all analog). What argument? Engineer?
Lentini was recalcitrant with regard to float for the same reasons he never bothered to make a UI for SAW or SAC that doesnt look like vomit - he didnt see the point in using float and he could never be bothered to design a nice UI. His excuse was his bias towards working in Assembler, which is understandable and one of the reasons for the much vaunted (and justifiable) reputation for stability which SAW/SAC commands.
He eventually gave in on the fixed vs float arguments, mostly because he got tired of fighting AFAIK.
But as to SAW/SAC _
sounding_ better than other DAWs? Just wishful thinking and projection. It does sound great, but so do other native DAW applications. Math is math.
But there's no arguing against the software's efficiency and stability, which is second to none due to Lentini's expertise with machine code and Assembler. And that's the real reason why SAC has a devoted base of users in live sound.
Still looks like vomit though!
