In case anyone else was interested, I heard back about the ipod delay problems I was having, ie, a 3 sec delay in sound when switching between albums necessitating starting the track over from the beginning.
This was the email:
"That does seem to be a glitch that appears on iPod classic units.
We are not sure why it happens, but I ensure you that there is nothing wrong with your HiFi-M8.
We are trying to figure out why that is happening and will update the firmware when we find a solution."
So.. that's good news in that it's not a unit specific concern at least not with the M8.
Hopefully there will be a fix but I suspect I will have moved on to a ZX-1 by that time anyway..
