Like DSims above, I think the rendering you see comes from a combination of sensor performance, lens characteristics, and software processing. If your sensor data was poor then no software can save you. If your lens has poor performance then your good sensor will save a poor image. Now, assuming you have a good lens projecting a good image onto the good sensor and you have good data from it then good software will really make your digital images stand out. Phase One definitely has something figured out right when it comes to their RAW processing in Capture One. The colors are indeed smooth and gentle but you're not limited in cranking up the micro-contrast and saturation (vibrancy). Their software has good sharpening tools and the noise reduction is OK. You should also note that their software was written primarily for professionals using MF cameras - and usually in a studio setting or some other controlled setting. It's made for portraits, fashion, and product photography. So their software is designed to make those kind of shots with the appropriate lighting look good, especially when shooting tethered. They wanted their clients to see excellent images straight out of the software with no fuddling or fumbling.
It didn't take long for the team to realize that they developed something special and unique. They decided to gradually expand their supported cameras list to include DSLRs and u4/3 since pros use those too. The market embraced their product so the expansion continued up to where you see it today. They don't and won't support everything. It's a commercial decision. For example, they will never support a competing MF body like the 645Z. You can read their user-to-user forum and find plenty of threads started by frustrated users who want to use their 645Z, Hasselblad, etc with Capture One. Phase One flatly says no. You are welcome to create your own work-around but that's on you.
I have switched to Capture One from Aperture and I also notice a huge difference in rendering. The base image, even when using their Linear Response curve, is very nice. Details are crisp, highlights are less washed out, and the image is sharper. Now I have a better starting point. I feel like I don't have to wrestle with the image as much as I did with Aperture. That doesn't make Aperture bad. It just means Aperture fell behind the times. Perhaps if Apple was serious about that program it would have been what Capture One is today.
Sorry, lots of thoughts and digressions here but the topic has been on my mind a lot too.
