Finally, I found a fix thats worked. And it's thanks to someone on this site. Sorry, I've forgotten who you were or where your original post on this but if you're reading this, thanks
The powered USB theory is incorrect. On the rPac DAC is a Green light when it's getting a signal. This turns red when there is no signal. So, you're watching a Youtube clip, the light is green, then the clip ends and the light goes red, then about 3 seconds later, you get the cut out sound and the DAC is dead. So when there is no signal, the Dac surely has to be receiving enough power, no problem, it's not using any power so the lack of power can't be the case. I suspect, some powered USB hubs are still sending some sort of trickle signal to the DAC keeping the signal alive. But I'm no expert so I could be wrong.
So, (and again thanks to a previous poster on here) I found this works http://soundflower.en.softonic.com/. When you're using this, the red light never comes on, when the Youtube clip ends, the green light stays on and the rPac stays alive, no cut out. I'm not sure of it's intended use but whatever it is, it does the trick. I've got mine set to 2 channel use (16 channel turned off) and max buffer size. And thats it, it all works AND I've got the rPac plugged into the Mac, not a USB Hub.
If I sound a little overexcited over such a small thing it's because it's been going on since Christmas when i bought the thing and have never really had it working properly since I got it.
Maybe Arcam themselves should take note of this and produce an App that goes with the rPac to solve the problem once and for all.
So thats it, go and get Soundflower...http://soundflower.en.softonic.com/
Glad you got it sorted, although if it's an issue that needs a work around or additional app, Arcam should still make people aware that this is the case.

just to add the 'real' solution...
when you plug the rPAC into your USB port, hold down the two volume buttons (the + & -) on the top of rPAC (or when plugging the cable into the back of rPAC if already connected to Mac) and the light will turn Orange. This indicates that it is now in USB 2 mode. You can then press either volume button and light will go red and it will operate as normal, but no issues of cutting out, funny glitch noises or anything else!!!
Hope this helps you all.
and is that not in the instruction manual?
This is a special, undocumented, mode/setting...
..........and the pressing the +/- buttons simultaneously trick doesn't seem to work all the time either ~ certainly not for me anyway.
you must make sure they are held down before plugging in USB cable & during plugging in, then u can press either button to resume normal operation
Thanks for that Palmman; but just to be sure i have this correct. I normally leave the rPac plugged in via the USB all the time. Do I therefore need to unplug it via the USB and then go through this routine? If so, that is a little awkward for a device which i think should be 'plug n' play'. I have tried the technique described above and it doesn't prevent the problem re-occurring.
I have since since received something from Arcam ~ however, this relates to a fix or upgrade regarding issues with Windows despite me telling them I use the device with an iMac so i'm not sure what use it is .
Following the question "Is that not in the instruction manual' I took the (slightly barbed) hint.....and guess what, it isn't. However, there is a warning about the device needing power or precedence over other attached devices so I checked the USB utility on the mac and it seems the device is plugged into a hi-speed USB port with nothing else sharing it?
To the poster above who recommended the Epiphany acoustics E-dac , I will be ordering one as soon as I can; i already have the O2 portable headphone amp and it is really excellent.
Smacks to me to be a little bit of 'shed engineering'. I would happily sell this device on but would feel I would need to warn anyone considering buying it that it doesn't work with a MAC. I'll also check with the hifi dealership I bought it from as to whether they have had many similar experiences reported with mac users. I appreciate it may sound a little whiny and £150 isn't a huge amount of money but it is irritating that it doesn't work as described.
When there are a number of customers all complaining about a product then there is surely something wrong with the rPac. i cant enjoy any listening without the rpac being been cut off .. I have tried to comtact the company but no replies..its frustrating beyond measure ..
the point is: despite some solution that some people has offered here on this forum..this product was meant to be plug and play ..so clearly should have never be a need for any tweaking or even for this forum to be existed at first place..i think rPac problem should be included in the review to forewarn future buyers..
