It's a good machine. Both machines can put out 25 cm-H2O pressure.
Yes one of our members did and I like the S9 VPAP Auto a lot. I find that it is gentler than the S8 VPAP 25 Auto was and the transitions from EPAP to IPAP are much smoother. My S8 seemed like it would sometimes get out of sync with my breathing and just run off on its own rhythm. I managed to reduce this problem to almost nil but it took a lot of tweaking. The S9 has been no problem.
I am extremely happy with the Climateline tubing which is not available on the S8. I was having to get creative with rainout solutions with the S8. With the S9 with Climateline it has been set and forget.
I also wanted to get the high sample rate flow rate data that the S8 does not provide but the S9 does.
The S9 is quieter than the S8 was not that the S8 was all that noisy.
I also like the 3 piece, stainless steel humidity tank for the humidifier in place of the standard 2 piece aluminum tank. The S9 tanks all come apart so that they can be cleaned more easily than the S8. The stainless steel 3 piece tank gives more even humidification as the level of the water drops than either the 2 piece S9 tank or the S8 tank. It has better air routing for moisture pick-up.
The water tank on the S9 is slightly smaller than the one on the S8 but it also seems to humidify more effectively and use a little less water.
I like the controls better on the S9. The On/Off button is easy to find in the dark and easy to activate and I like the way the scroll and select knob works.
If you are getting the idea that I was really happy with my upgrade from S8 to S9, you would be a little under the mark. Yes, I am ecstatic.
Edit: Sorry, I reread your question and found out that I answered the wrong question.
