A downside to a system like that is that you are very tied to the computer and the software. Very reliant on the custom computer software to be supported and updated for future OS versions. Very reliant on the computer hardware being continually supported. Will you still be able to use your $10,000 digital audio front end in 5 years? Will it even be possible to get it working in 10 years? My 30 year old CD player still works. My 30 year old Apple ][ computer stuff is long dead and is only capable of seeing the present day in software emulation mode. That Spatial system relies on FireWire to talk to the digital hardware. Apple is not exactly staying enthusiastic about FireWire. Apple removed FireWire from the low end laptops. How long will it even continue to be available on the desktops? Will the OS even support FireWire in 5 years? This type of consumer computer gear integration is destined for the rapid consumer electronics upgrade/obsolescence cycle. Not a good way to "invest" audio dollars. Look at how fast iPhones are obsoleted. Do you want your $10,000 digital audio front end obsoleted just as fast?
I'm a computer geek. I'm a software engineer. I'm not enthusiastic about integrating expansive digital gear with custom software running on a consumer computer. It will work now. Unlikely to continue working in just a few years.
