Thanks for the input what I experienced with the SiX was that the output I ran through it just sounded great, but it did miss that little extra something, which I felt the Fusion brought to the table. However, I’m thinking that extra something partly had to do with the fact that I only had SSL EQ on two tracks or the master, and the Big Six offers full EQ on all tracks, and a slightly enhanced compressor.
I tend to not use much else anyway for mastering, except then perhaps a little space enhancer, which I could get as a separate thing if that remained an issue.
With the Fusion, I didn’t much use the Drive, the onboard secret compressor, the HPF compressor or the low end boost. There was a difference between their on and off states, but not one that mattered when compared to the HUGE difference the EQ and stereo enhancer provided. And the SiX compressor was superior to the Fusion’s for my purpose.
In general, I felt the Fusion probably came more into its own for non-electronic music, where I can imagine dynamics are more all over the place with guitars, vocals, drums and stuff just fighting for space. In a modern, tight electronic music context, you can get pretty far creating at tight mix just within whatever box you’re working with, before you’ve even applied that final touch of magic to it.
I felt the SSL kits brought just that final touch, but that my rig was overkill. So I’m looking to return to it, but more streamlined this time.
I’ve also considered getting the Bus+ instead, and just work on the stereo signal directly and not even bother with separate mixing outside my boxes.
