i have been using a yamaha cdc-685 5 disc carousel for the last 4 years without a problem. i am always using the remote volume control and it works fine. i believe it works in a 20 db range like the sony mentioned above. it's lowest setting will mute the volume entirely for you. the unit's display has a 5 bar read-out to show you the volume output. i can barely make it out from my sitting position 10 feet away. you can still by this unit new for about $220 at tweeter or online for less. build quality is better than the sony carousel although it does cost more. i feel it offers excellent sound for the price. check it out!
regards,
paul
