Any thoughts on how to tweak the volume button on the MX-980 so that it is quicker to go up and down? The original remote from the McIntosh mx-121 is much quicker to go up and down. While the current setting works in terms of one touch of the mx-980 volume button up or down moves the volume one half decibel up or down, it is not as quick when you hold down the button. Thanks, D
