You might find that that is going to be a good match. To me, the tweeters on the Large Advents can sound rather harsh on some material, especially as the volume goes up. (Keep in mind that I play mine in a "hard" room.) I tried several receivers with my "stacked" two pair of OLAs before I found what I think is a very good match with the Nikko NR-xx15 series of receivers - more specifically the NR-815 (55wpc). There is just something about the nature of the "smooth" sound from this series of Nikkos that mates well with those Advent tweeters.
I have never had the opportunity to try the series of HKs you mentioned with my Advents. But I have read that some like to pair those x30 HKs with some Klipsch speakers that can sometimes trend toward forward or bright. But I've found that pairing receivers to speakers just by what some say on the web is tricky. I think there are often just too many variables, like our individual ears and tastes, different music sources, effects from the room, etc.
Hopefully someone will come along here with some more specific info. Good luck, and if you do try them together, please let us know how you think they sound.
