Ronnie I don't think you have inappropriately prolonged the issue with your very clear and useful explanation.

It also relates to some difficulty I had with the info coming down the chain to me from Meridian with making sure I could separate as much as possible the 808.3 CD playback improvements from improvements via analogue inputs.

Ronnie I would also expect some improvement that is hopefully audible from 24/96 digital input to 808.3, such as from better clocking. Time and listening will tell.
