Musical Fidelity A5 Integrated, Use as Preamp Only

The Musical Fidelity A5 Integrated has Pre-Out connections which the manual states are for bi-amplification, allowing the use external speaker amplifiers while typically leaving the tweeters connected to the MF A5 amplifier section.

Some have suggested this implies that the MF A5 amplifier section should not be operated without any load.

I would like to connect the A5 pre-outs directly to my recently acquired separate power amplifier thereby using the A5's preamplifier section only (with no load on the amplifier section) until I get a separate preamplifier. I do not, however, want to damage the the A5 by doing this.

I wonder if anyone has experience with this. (I have submitted the question MF UK and am awaiting a reply, but hearing actual user experience is extremely important to me.)

Thank You
