The on/off button starts and stops both the pump and platter rotating. There’s a slightly perceptible hum sound from the pump when you first engage, but after achieving suction (about 5 seconds) the pump automatically goes into a reduced/maintenance mode and pretty much disappears even with no music playing.
If you’re the type who likes to flip over your record while the platter is still spinning, you can’t do that with the Sota Star. You need to turn off the table, flip the record and then turn back on - to start the suction process again.
With that table, tonearm, cart, phono combo you should be all set for now. Once you live with that setup and decide if you want to upgrade your cart, then you can go down the road of figuring out if you want to upgrade phono or not.
That’s great that you have spouses pre-approval. The Sota is a lot bigger/heavier in person.
