Help using integrated as power amp


I have a NAD T747 receiver powering some Totem Rainmakers. Problem is that the 747 manual states the receiver should be used to drive 8 ohm or higher. I have an old arcam alpha 9 integrated amp and was thinking of testing out using this as a power amp for the rainmakers and the 747 as the preamp. Can anyone explain how to do this? Do I need to be careful with the volume controls, I am not even sure in this situation which volume controls work.
Thanks.

If the T747 has tape outputs you could run those into an AUX input on the Arcam and then use the volume control on the Arcam. It should be simple enough.
Whats wrong with the preamp in the Arcam?

If it is the tuner section section in the receiver you wish to still use from the receiver, use the tape output of the receiver connected to a line input of the Arcam.
The pre-amp section of the Arcam integrated would certainly sound better with a good quality source than the pre-amp section of the T747 Receiver. I have owned the same T747 receiver myself, and any Arcam integrated amp will sound better than the T747 does by a long shot, unless you don't like to hear detail, dynamics and clarity in your music....
