Rega Hal - preamp outs

I picked up a Rega Hal for almost nothing, and once I got a look at the manual found that the pre-outs are non-standard (I assumed they were normal balanced outs). The manual does little to elaborate on connecting this to Non-Rega, normal amps. Can somone please help me with the following questions?

1) Has anyone driven non-Rega, unbalanced input power amps with good results?

2) How are the pre-out pins configured? I assume that the bottom pin is ground, left is left, and right is right live output. Please correct me, or confirm. If I construct an interconnect with two normal RCA terms on the Amp side, connected to the correct pins of an XLR term on the pre side - will this drive most any power amp with good results? And more specifically, will it drive my B&K Reference 4420 well?

3) Can you recommend where I can obtain an adapter to save the trouble of constructing one? (I am also contacting Rega NA for this question)

4) Is all of the above likely to be a fool's errand (or worse), and I should just look to pair this up with one of the matching Rega Power amps?

thanks to everyone in advance!
