Thanks for the suggestions guys.
@Professorhat: I do eventually want to get a full stereo set-up, of which any new DAC I purchase will be a part, so a dedicated stereo amp will be a future purchase, but not one I want to make (or rather can afford to make) at the moment. I would rather concentrate those funds into a dedicated DAC at this point, and settle on an amp when I know what stereo speakers I might get (especially as my current speakers are really intended more for movie soundtracks than stereo listening). I don't want to dismiss them without having even listened to them, but I wonder if the Arcam or Rega will struggle to make any improvement on the Poinerr given their price point? Have you tried them versus your Onkyo?
@ nick8858: For this reason, though the iDecco2 (infact all the Peachtree stuff) looks like a lovely bit of kit (especially with that tube amp in there!), I would rather get a straight DAC at the moment as I would have to trade an iDecco in if I moved to a dedicate steroe seperates set-up with seperate amp (or active speakers).
@ Dr Lodge: You mention the Cyrus 8 XPd, again thisis an integrated amp, so not realy what I am after, but how does the Cyrus XP+ DAC compare to others out there?
I have to openly admit, the whole idea of a seperate DAC is a little new to me, so I don't know whether getting an expensive DAC such as the Cyrus is worth the investment, not just now, but in the dedicated stereo set-up I set up in the future - or whether they are actually worth every penny and I should invest an amount in one, in line with the other componets I might be looking at when it comes to it (such as the CD player, amp etc).
