I have been a Sota owner for 23 years. Star, Nova and now Cosmos IV. I could never live without vacuum hold down. I just received a few vinyls from Cisco and Naim and they look like a salad bowl. Badly warped. Without vacuum hold down those would have to be returned. On the Cosmos, they are sucked flat onto the platter. The power supply housing the pump inside is DEAD QUIET. No hassle at all. Go for it buddy....go for it without hesitation. Call Sota 608-538-3500 and speak with Donna or Kirk.
All the best....
