A rush decision or purchase of speakers (mains in particular) without listening to them often leads to one thing: upgradeitis. Take it from me and others here that will attest to this, I learned the hard way...
While the RF-82s might be exactly what your friend is looking for, speaker preference is quite subjective and without actually listening to RF-82s (unless he's heard them before), he might wind up with mains that are okay, but not exactly what he wanted. I've heard some Klipsch that sounded great (RF-5s, RF-7s and Klipschorns), but I've also heard some other Klipsch models that didn't sound so great.
As your mains are the core of your system, I would strongly recommend having your friend listen to them to make sure they are for him, in-home if at all possible.... -TD
