Looking for a New Machine - Quiet and Effective

I've had a ResMed System One for five years. It's starting to wheeze a bit and keeps my wife awake sometimes. I'm wondering if any of you have recommendations on an excellent replacement that is very quiet, easy to operate and, of course, does a great job of providing constant pressure. I'm also wondering if a heated hose is the way to go. Thanks.

Hello Video Guy, I have used both Respironics Dreamstation and the machine I have now is the ResMed AirCurve 10 ASV. Both seem to be quiet, but they are obviously very different machines. I do like the heated tube in the winters of Colorado but not sure if I would want it if I were in a coastal city. I think all of the new model machines are going to be similar as far as how quiet they are, but have only tried the two brands above.

Any new machine will be small and quiet. All of them will deliver suitable pressure. The differences are in the small things. I mainly deal with Fisher & Paykel, ResMed and Respironics because together they make up about 98% of the global market.

The Respironics Dream Station has the simplest humidifier design I've seen, and has nice, simple controls.

The ResMed AirSense range has a pretty simple humidifier but the menu-based interface can be a bit complicated for some people.

The Fisher & Paykel Icon series is the cheapest and smallest option if you use a humidifier, but the humidifier itself can be fiddly to use and can't be opened for cleaning. I also greatly dislike the icon-based menu. Fisher & Paykel have just released a new machine called the SleepStyle. I have yet to get my hands on one but it looks to be smaller than the Icon (so therefore the new smallest option available if you use a humidifier). It also appears to have simplified the controls (no more bothering with the silly icon-based menu) and the humidifier design has been updated, but I cannot attest to how good it is. Just google Fisher & Paykel SleepStyle to get some more info. It looks like it might be very good but I can't be sure until I've actually had a play with one.

As I said they are all very similar in most ways , so the best one for you comes down to the small differences. By the way, have you cleaned the filter of your current machine? A dirty filter can be the cause of some noise.

I've tried to be general here, but if you have some more specific questions feel free to ask.
