Perhaps I should add that I bought a BKool and not the KK Road Machine or the Tacx Bushido.
There is some noise(most notable when going downhill) but I think it's great to be able to see your poweroutput and rpm on the screen and the heartrate when I get an ANT+ strap and it add diversity to the rather boring indoor riding that you can choose to ride different routes.

I have not yet tried the live videos because I have the basic subscription ATM but the trainer comes with 2 months of gold subscription and I will activate it in a forth night or so. When I get back from vacation and get some more training in.

I have to second this. I was going to respond with the 1up recommendation before I even saw Geoff's reply to the OP.

The 1up is quite quiet, has pretty good 'road feel' (for a trainer, so take that with a grain of salt), and has enough resistance to do workouts that involve z5, z6 work. Set up with a proper trainer tire and it is about as quiet as they come.

I live in a place with long winters (indoor riding is typically November through April) and got plenty of use from my 1up trainer. I more recently switched to the Inside Ride / E-motion rollers (coincidentally, 1up sells these, too, though they don't make them; the share a similar design aesthetic). They are significant because they have resistance, so it is the one set of rollers that I know of where I can get a great power-based workout.

I believe the 1up trainer is about the same noise-level as the Inside Ride rollers.

As mentioned directly above, I use the Inside Ride / E-motion rollers. I do out-of-saddle efforts on them, as well as z5, z6 work. I tend not to do all-out sprint (8-12") efforts on them, but when I want to spice things up I will do very hard efforts. 700-800w is not inappropriate for them. One could probably do max (short) sprints...it's just that I happen not to work on that during the winter, not that I think the unit is not capable.

I notice that as good as the 1up trainer is, after many months of riding a trainer I lose some of the subtle motions required to control a bike. Takes a short while to re-learn this out on the ride, so not a huge deal. However, with the rollers I find there is no transition time...not even a minute.

Just some things to consider.

I still occasionally use the 1up for some very hard sessions on the TT bike (feel a little more comfortable redlined on the TT bike on the trainer vs rollers), and for race-day warm-ups.

1up usa is quiet but I can not recommend as I also have the kurt kinetic which is only slightly loader and a much better trainer.

Cant comment on the KK Road Machine but my Tacx Bushido and Vittoria Home Trainer Tire, is significanlty quieter than our Tacx Fortius and I would say that the 18" floor fan running in front of the bike makes much, much more noise than the Bushido.
