Aside from the MS-8, all other DSPs at the same price level require someone at the helm who knows how to tune, as well as an RTA setup. When you have many, many equalizer bands there is literally no productive use of your time to attempt to tune only by ear. While the MS-8 is not perfect, and the installation manual is missing critical tips, I can have my system tuned from scratch in less than 20 minutes. I do this every time I have done a memory wipe on my MS-8, which has been twice so far in the last 7 months that I recall.
At an Audison dealer with a Bit Tune you can pay them to tune your system more or less automatically. I don't know any Audison dealers near me to be able to see this in person, but you can see it on YouTube on the Amplified show by Soundman in California. You're chained to the dealer if you ever need to retune the system with the Bit Tune.
The point of possibly quadrupling the complexity of a system with a DSP and the options they can open is because the results can be mind blowing. It's not going to make a ****** install sound competition ready, and it can't make crap speakers sound like high end speakers. It can make good speakers sound amazing, and along with an install that covers a lot of common issues you start to forget you're in a car at times.
