Attempting to get this thread back on course....
 
My question had nothing to do with AUDIO QUALITY, but with APPLICATION (DAW) PERFORMANCE and RELIABILITY.
Seems logical to me that the less unrelated tasks the CPU is performing, the better the application will perform.
 
I was hoping that someone had experience or knowledge, even second hand, of whether AO works with a DAW, as opposed to simple streaming applications, or if it shuts down services required for DAW functionality.

I'm putting on my help hat now. Your question is a very good one. The trouble is that DAW usage and quality playback of digital audio are to a great extent unrelated. What I mean is playing back audio is not a strain on anything. An MME driver is all that is needed. DAWs on the other hand demand as much system resources that are available.  Optimizing for quality audio playback is more about the quality of the playback gear. It isn't about limiting resources for the rest of the system. On a modern system all things being equal I think what they are offering is selling coals to Newcastle. You don't need it.    
 
I guess I should have taken your question on face value in the OP.  I would be very cautious of anything on the net that promises to make things better. In a way they can't loose if you buy it the placebo effect will work for them even though noting is really improved.

Tell ya what, find proof that their claims are fraudulent, I'll pay the lawyer and we'll split the take. You can't, because sound quality is subjective. Audiophiles don't CARE about your science, or what your spectrum analyzer says, or what YOUR ears tell YOU, only what THEIR ears tell THEM. To call them dupes for buying things like AO is pretentious at best.

Music is subjective, sound quality is not. It can be objectively measured. Granted, measurements can identify flaws that are too subtle for the ear to distinguish, and we all subjectively decide where that threshold lies. You may not care about science, and that's OK, but high-fidelity audio only exists because other people before you did. 
 
Strictly speaking, we are all audiophiles here, insofar as we all care deeply about sound. We only eschew that term because of its negative connotations, specifically its use by unscrupulous marketers to fool naive customers. People who say things like "experience analog-like sound as you have never heard it before". Sadly, "audiophile" has become a red flag, and we've become wary of any product that has "audiophile" in the name or description.
 
Such products are often ridiculously overpriced and/or ineffective, such as $109 SATA cables that claim to "reduce digital glare" and $130 USB cables that offer "better sound quality". Claiming a USB cable can improve sound quality is not a subjective opinion, it is a demonstrably false assertion - what in simpler times we would have simply called a "lie". 
 
This does not mean AudiophileOptimizer is a scam, only that the seller is dishonest and/or naive. Run AO at your own risk, and only after making a full system backup. Personally, I would not go near it.
