That will be your best approach but beware that you can easily blow your speakers especially if all your music is not at the same level or all the inputs on your receiver are not leveled the same.

It is also very easy to have your receiver muted and then think that the volume is too low and press the right-most button at which time your receiver comes off mute and you risk blowing out both your eardrums and your speakers.

Take it from me as I have developed multiple TCP/IP versions of a Denon/Marantz module and have experienced this first-hand, especially with the Denon/Marantz Ipad app. :-(

I always use volume ramping and if volume is <-20db, I can ramp +2db at a time but anything above that ramps at only 1db moving up. Of course, going down is not an issue and I can jump -2db without any issues.
