I also highly recommend the Placette Passive or Remote Volume Control. Both models are remote controlled, it's not an option. The difference is the Passive has three inputs standard and the RVC has one input. The Passive new is $1400, used generally $800-$1000. RVC is $1000 new and $600-$700 used.
I don't think you will find a better sounding unit for the price, and the remote is a bonus.
