I'm Alan Kaye, currently from Alabama. I have a Saffire Pro 24, and the story of why and when I got it is rather interesting. I have been a fan of Firewire throughput for some time, for stability in higher standard audio recording and video, so I have always used a Firewire box. When I got my first one, it was only between Firewire 400 or maybe 800 and USB 2.0. It was for home recording.
So, I had a different AD box from a company I like, and on Thanksgiving weekend a couple of years ago I got a great deal on a new computer. After reading up on Windows 8, and not being afraid to hop into the new environment, I got it with Windows 8. Then, upon transferring my stuff, I discovered that the AD box would not work with that OS, and I would be required to buy a new one.
Looking for alternatives that would immediately be Win8 compatible AND would be reputed to have "award winning" preamps like my previous box, I came upon Focusrite. That was exactly during the rollout of Win8, and lo and behold, the Focusrite Firewire boxes were compatible. Yet, the real icing on the cake was not any of that but a simple power switch on the box itself, something I had never had before. Not having a switch required me to unplug the box if I didn't want it to attempt to become my sound card on booting up. That's not always a bad thing, except that my studio monitors have to be turned on separately, and so forth.
I chose the 24 over the 24 DSP because I didn't want to fuss with what sound model I was using, but I've since regretted not having multiple monitoring choices that the DSP would offer. I hope this box lasts several more years, but when I replace it, I will probably cough up some extra dinero for the DSP.
Styles I record include bluegrass, various styles of MIDI generated music, and rock. Of course the Saffire handles all that beautifully. Since I am paranoid about starting at too low of a quality level, I count on the Saffire to process my sounds in the finest granularity it is able to produce.
Here's a video I made with a digital SLR, processing the audio in a Presonus Studio One project and adding bass, drums, and organ to round out the sound, greatly assisted by the power of the Saffire Pro 24.
