XLR out on a tuner?

I'm new to hifi and not an audiophile yet but learning a lot lately.

I'm following a Denon DN-300H tuner on the big auction site. It looks very clean and has a remote. I also noticed on the rear it has XLR cable outputs as well as RCA out. Is this sought after? Worth paying extra for? My pre-amp (Acoustic Research LS16) has two open XLR input ports marked Bal1 and Bal2. The price on the tuner is okay and if using XLR cables through the balanced input on the pre-amp is an advantage I might just buy it.

Any assistance much appreciated.

I have an MD 105T with both balanced and RCA outputs. I've tried both, with no discernable difference, as the distance between the tuner and preamp is very short.  IMO, balanced lines are good over longer distances; however, since the 300H is meant for rack mounting, you could go with balanced interconnects throughout. 
Thanks for that. In my case the distance will be no more than a foot or two. I've got some good quality RCA cables that I can use for this application. A good set of 3' World's Best Cables XLRs would add another $30 to the total if I felt like I needed them.

If I did go with the XLR cables then the whole system (other than CDP) would be balanced, if that matters. It would be XLR from tuner to pre-amp and it is already XLR from pre-amp to amp.
@n80. Did you relocate your ARC pre and CDP away from your amp and speakers?
