Carol,
Thanks for your input, but the upgrade kit I'm talking about is the kit that
modifies the Mark II Control Box.  I'm not talking about the Mark IIXG
Control Box add on.
I am specifically looking for the answer to the question about the CD player
and the modified Mark II control box.
I know that Yamaha's silent feature is the best, however, I'm looking for
more definitive info on Third Party Mute Rails.
I'd love to but a Mark III, however, I just don't have the spare change at
the moment.
